Ghafar Ismail Nur Azura Sanusi Since the pioneering work of Gurley and Shaw . , the attempt has been done to justify money as a primary focal point of macroeconomic theorizing. However, other researchers argue that variables such as financial development and indicators are also important to be linked with macroeconomic performance. Here, if money can be thought as means of production and consumer goods as the ultimate end toward which production is directed, and then capital also occupies a position that is both logically and temporarily intermediate between original means and ultimate ends. This temporarily intermediate status of capital is not in serious dispute, but its significance for macroeconomic theorizing is rarely recognized. The firmsAo decision to acquire funds through debt and equity financings affects the capital structure, and, in the firmAos balance sheet, the impact of capital appears to influence the inventory Hence, the significance of capital structure Aeinduced inventory distortions in the context of firm-level is the basis for our The sample for our analysis is compiled from the balance sheets of listed syaria firms in the Kuala Lumpur Stock Exchange for the period 1995-2000.

Vol. No. Introduction Most of macroeconomic theory is based on the idea of perfect capital markets, that is, smooth functioning of financial systems that justifies abstraction from financial considerations. Beginning with the seminal work of Modigliani and Miller . , the idea that financial structure was indeterminate and irrelevant for investment decisions has heavily influenced modern The major developments in investment research in the 1960Aos, the neoclassical and q models,1 made use of Modigliani-Miller proposition of isolation between real firm decisions and financial factors. However, empirical work has traditionally produced results inconsistent with the notion of Aufinancial irrelevance. Ay In particular, evidence has been found on: . the role of breakdowns in financial trade in historically important economic contractions, . the role of movements in internal finance in predicting investment, . persistent differences in the way certain types of firms raise finance, and . the regular cyclical movements of financial variables . , balance sheet positions, liquidity ratios, and bank In order to reconcile theory and empirical studies in finance and investment, recent research has made use of models in which informational asymmetries between AuborrowersAy and AulendersAy introduce incentive problems in financial relationships, creating informational frictions and making financing and investment decisions interdependent in specific ways. Then Blanchard and Fischer . point out that the work attempting to account for certain features of the financial markets from the viewpoint of asymmetric information is extremely important and that it will be increasingly integrated in complete macroeconomic Later, much of this research has proceeded in two agendas, modeling: the role of asymmetric information in linking movements between finance and investment, holding constant underlying opportunities, and . the importance of information problems in accounting for observed differences in financing patterns and mechanisms for corporate control. Based on this background, the motivation of this paper is to produce the empirical evidence of investment that is expected to be more sensitive to current cash flow than a frictionless neoclassical model would predict, with results stronger for fixed effects. The rest of the paper is organized in the following way: the next section explains the theoretical background. model used, data sources and estimation procedure are outlined in the third empirical results are examined in the fourth section. and the fifth section summarizes the conclusions. For the neoclassical model, see Hall and Jorgenson . On q models some references are Brainard and Tobin . Tobin . , and subsequent developments in Hayashi . Summers . , and Abel and Blanchard . Ismail & Sanusi AiAn Empirical Analysis of Cash Flow and Investment Fluctuations . Finance and Investment The severity of the Great Depression, as argued by Fisher . , was partly attributed by the heavy burden of debt . high leverage of borrower. and consequently, business downturn precipitated a wave of bankruptcies, enhancing the downturn. Then, the macroeconomics literature following the General Theory . Keynes 1. largely ignored potential links between output behavior and the performance of credit markets. He emphasized the indirect connection between financial markets and real activity resulting from KeynesAos liquidity preference theory, shifting the emphasis to money as the financial variable most relevant to aggregate economic Then. Gurley and Shaw . began to redirect attention toward the overall interaction between financial structure and real activity, emphasizing financial intermediation, and particularly the role of financial intermediaries in the credit supply process as opposed to the money supply process. 2 Noting the differences in financial sophistication between developed and underdeveloped countries, they came to the conclusion that the role of intermediaries in improving the efficiency of intertemporal trade was an important factor governing economic A corollary argument was that restricting attention to the money supply made it impossible to properly characterize the link between real and financial activity. Gurley and Shaw argued that more relevant to macroeconomic behavior than the money stock was the economyAos overall Aufinancial capacity,Ay that is, the measure of borrowerAos ability to absorb debt without having to reduce either current spending or future spending commitments. The behavior of balance sheets, as key determinants of financial capacity, assumed an important role, and intermediaries were relevant because they extended borrowerAos financial capacity. The change in macroeconomic views appeared in 1958. Modigliani and Miller . ater known as MM theore. derived the formal proposition that real economic decisions were independent of financial structure in a setting of perfect capital markets. As a result, financial variables started disappearing from empirical investment equations in the frictionless markets. Another factor that helped to take attention away from financial factors was the methodological revolution in macroeconomics in the 1970Aos, that emphasized the development of macroeconomic models explicitly from individual optimization . Blanchard and Fischer 1989, and Diamond 1. However, the modification of individual optimization . the introduction of heterogeneity among agents and mone. become the motivation for trade in the business cycle theory. Several important papers that supported this idea are Kuh and Meyer . Tobin and Dolde . Brainard and Tobin . Minsky . and Kindleberger . , and Tobin . Gadjah Mada International Journal of Business. January-April 2005. Vol. No. A renovated interest in studying the financial aspects appears to explain the business cycle theory. This interest arises as a result of progress in the economics of information and incentives. Both provide with useful techniques for formalizing financial markets frictions. The basic insight of the new work is that inefficiencies in trade could arise due to the existence of asymmetric information between the agents participating in the market, that is, the existence of informational advantages for either of the agents involved in the transaction. In addition, this type of informational problems could be solved, or at least minimized, creating incentives with the use of contracts or other types of institutional devices such as screening or monitoring. The existence of asymmetric information has encouraged other researchers . Hubbard 1990. Hubbard 1. to advance the investment process in the presence of imperfect capital market. He explains that interest by contemporary researchers in links between Auinternal fundsAy and investment decisions reflects two main concerns, one AumicroAy and one Aumacro. Ay The AumicroAy concern relates to consequences of informational imperfections in credit markets. Problems of asymmetric information between borrowers and lenders create a gap between the cost of external and internal financing that gives internal finance an essential role in the investment decision of the firm. Moreover, the level of internal net worth becomes a critical determinant of the terms under which firms can borrow, holding constant true investment opportunities. The AumacroAy concern is that cyclical movements in investment appear too large to be explained by market indicators of expected future profitability or the user cost of capital. As Hubbard . states, to the extent that a sufficient number of firms must raise finance in markets lacking perfect information, microeconomic market failures can generate correlations in aggregate data different from those suggested by standard models of investment or the consequences of macroeconomic policies. In particular, interest rates are de-emphasized as the main determinant of borrowing and investment, with movements in internal net worth of corporate borrowers . , cash flow. being relatively more This has led to identify financial factors in propagating relatively small shocks. The micro concern is extended further by Romer . especially on the allocative effects of informational problems in financial markets. As he describes, when firms and investors are equally well informed, financial markets function efficiently, and investments are valued according to their expected payoffs and riskiness. However, in practice, firms are much better informed about their investment projects than potential outside investors are. In addition, the existence of intermediaries between the ultimate investors and firms means that there is Ismail & Sanusi AiAn Empirical Analysis of Cash Flow and Investment Fluctuations . a two-level problem of asymmetric information: between intermediaries and firms, and between individuals and intermediaries. The literature on the economics of information and incentives distinguishes two general types of informational problems that generate frictions in capital markets and can then be used to explain why lenders may ration credit rather than raise interest rates to clear markets. These problems are: first, adverse selection, following Gale . and Mas-Colell et al. this problem arises when an informed individualAos trading decisions depend on her privately held information in a manner that adversely affects uninformed market participants. In this case, asymmetries of information exist between individuals at the time of With imperfect information about the quality or riskiness of the borrowersAo investment projects, adverse selection creates a gap between the cost of financing in an uninformed capital market . hich incorporates a AulemonAy premium, see Akerlof 1. , and internally generated funds. Second, the principal-agent problem . efer to Grossman and Hart 1983, and Hart and Holstrom 1. , in this case, asymmetries of information develop subsequent to the signing of a Two types of problems have been distinguished in this setting: those resulting from hidden actions, also known as moral hazard, produced by the inability of, for example, the owner of a firm to observe how hard his manager is working. and those resulting from hidden information, in which the manager possesses superior information about the firmAos opportunities. In the credit market framework, it is the second type of problem, hidden information, the one that is considered in the literature. 4 Due to the presence of incentive problems and costly monitoring of managerial actions, external suppliers of funds to firms require a higher return to compensate them from these monitoring costs and the potential hidden information problems associated with managerAos control over the allocation of investment funds. A problem of the models discussed thus far is that they are highly sensitive to exogenous restrictions The role of intermediaries in overcoming imperfections in markets which transfer funds between savers and investors has been stressed by models of financial intermediation, that apply first principles to explain the existence and structure of intermediaries, and to describe how these institutions may interact with aggregate real activity.

Vol. No. made in the form of the relevant financial contracts, since they use a very restrictive form of debt contract. 5 This raised the question of the robustness of the credit-rationing result, encouraging other researchers such as Townsend . Gale and Hellwig . , and Williamson . , that attempt to explore the effects of financial market inefficiencies without making a priori assumptions about financial structure. Under this approach, the real/financial interaction is a purely endogenous The endogenous interaction between financial structure and real activity in a market with a general type of lemons problem is further explored by Bernanke and Gertler . This lemons-induced rise in borrowing costs reduces the efficiency of the investment process and in severe cases may induce an investment collapse. important implication is that informational distortions can, in theory, have quantitatively significant effects on investment behavior. In addition, the conclusions extend beyond situations where simple debt contracts are the exclusive financial instruments. Why incorporate credit market imperfections into mainstream models of macroeconomic fluctuations? Although Bernanke. Gertler and Gilchrist (BGG hencefort. state several reasons, but in the context of standard dynamic macroeconomic models, they show that credit market frictions may significantly amplify both real and nominal shocks to the economy. This financial accelerator effect is a step toward resolving the Ausmall shocks, large cyclesAy puzzle traditional in business cycle analysis: large fluctuations in aggregate economic activity arise from what appear to be relatively small impulses . uch as modest changes in real interest rates induced by monetary 6 Moreover, credit market frictions help to explain a broader class of cyclical phenomena, such as changes in credit extension and the spreads between safe and risky interest rates.

Kiyotaki and Moore Fischer 1996. and Carlstrom and Fuerst 1. share the idea that, in the analysis of macroeconomic dynamics, balance sheet indicators should be thought of as state variables. That is, financial conditions matter for cyclical behavior. Testable Models By adopting the Fazzari et al. (FHP hencefort. , we try to test whether determinants of investment differ between firms for which, a By using the Stiglitz-WeissAos . framework, the non-optimality of credit rationing . here is too little investment at the credit-rationed equilibriu.

FHP extend a model from the public economics literature, in which dividends are a residual in firm decisions. 7 The idea is that, supposing a higher cost of adjusting the capital stock relative to adjusting dividend payouts, and that the cost of external finance exceeds that of internal finance, the investment of firms with good investment opportunities that retain all or nearly all of their earnings will be more likely to be sensitive to cash flow than that for high-payout firms with a large . cushion of funds to finance investment. So the FHP framework can be interpreted as using cash flow to measure the change in net worth. Although firm cash flow is an imperfect proxy for the change in net worth, most studies . Bernanke and Gertler Calomiris and Hubbard 1990. and Bernanke and Gilchrist 1. use it because it is virtually the only such measure available for many firms. Using cash flow. FHP estimates the following model: EOCF A bQ it A c EA it EA K it A1 EUK it A1 I it A v t A e it . where i and t denote the firm and time period. I is investment. K is capital stock. CF is cash flow, and average Q, constructed from financial market data, is used as a proxy for marginal q,8 substituting expected average returns to capital (ROE) each period for marginal returns. In this specification vi denotes firm specific effects. Since the estimation for equation . uses the panel data and relate to individual firm, so there is subject to be heterogeneity in these firms over time. In order to take such heterogeneity explicitly into account in our estimation procedure, several assumptions about the firm specific effects term have to be Therefore, in our estimation, four different effects are assumed, i. common, fixed, random and time effects. In Equation . , we hypothesize that the decline in the cost of financing causes the decline in the expenses of the firms. Consequently, this affects the cash flow of the firms and persistently the value of collateral . et wort. and the position of firmAos balance Therefore, cash flow could im- This idea comes from the tax capitalization model of the dividend decision in the public economics literature. In that model, internal funds are cheaper to the firm than external funds because dividends are more highly taxed than capital gains. According to Hayashi . , average and marginal q are equal for the model with an assumption to have constant returns in the adjustment costs. The constant returns in the costs of adjustment imply that q determines the growth rate of a firmAos capital stock. Gadjah Mada International Journal of Business. January-April 2005. Vol. No. prove the firmAos current financial position and increase internally the funds available for investment, investments should respond positively to increases in cash flow. In the absence of capital market frictions, the estimated coefficient c should be zero as long as Q controls adequately for investment opportunities. a significantly positive value of c corresponds to a rejection of the frictionless model and a suggestion of the presence of financing constraints. We also group firms into three fixed categories: low, medium, and high dividend payout. The result is expected to find significantly larger estimated cash flow coefficients, c, for the low-dividend-payout firms than for the high-dividend-payout firms. is this cross-sectional difference that may lead us to conclude that financing constraints are likely to be important in many firmsAo investment decisions. This finding has been corroborated in studies of firms for Japan (Hoshi et al. , the United Kingdom (Devereux and Schiantarelli 1. Italy (Schiantarelli and Sembenelli 1. Canada (Schaller 1. , and Germany (Elston 1. Also, using panel data on U. manufacturing firms. Hubbard et al. find similar results to those of FHP using a pre-sample dividend classification.

The analysis in this section reports the descriptive analysis and the regression results by using the panel data estimation. Table 1 shows the descriptive analysis results for the low dividend firms, middle dividend firms and high dividend firms. Generally, the investment values show that the investment for the high dividend firms is larger rather than the low and middle Ismail & Sanusi AiAn Empirical Analysis of Cash Flow and Investment Fluctuations .

The same trend is reported for capital stock and cash flow based on the mean and the median values, respectively. While for Q, low dividend firms report a higher mean, median, and standard deviation values compared to the middle and the high dividend firms. Based on the mean values, the results imply that the high dividend firms tend to have higher investment, capital stock, cash flow and low Q. This section analyzes the estimation results. We run four different models . ommon effects, fixed effects, random effects and time effect. for each firmAos category. But after the screening process that considered the best adjusted R2 value, the r value compared to the F-value for the GLS model and the significant coefficient, we conclude that the GLS method with fixed effect model are the best for each estimation for different firms. Table 1 reported the estimation results. As reported in Table 2, the result shows that the estimates for the cash flow coefficients are of the right sign and significant. But the increases of investment are larger for the middledividend firms rather than the highdividend and low-dividend firms. This implies that the cash flow of the middledividend firms is more sensitive to the investment rather than the high and low-dividend firms. According to FHP, firms that retain all or nearly all of their earnings in investment are more likely to be sensitive to cash flow than the high-payout firms with a large . cushion of funds to finance While for Q, the coefficient is statistically significant and of the right sign for the high-dividend firms. According to TobinAos q theory, the firms increase its capital stock if q is high. An increase in capital stock increases the investment. But the coefficients are of the unexpected sign for the low and middle-dividend firms. The result shows that an increase in the firmAos capital stock decreases the firmAos investments. According to Romer . , a firm increases its capital stock if the market value of capital exceeds the costs to acquire the capital. Maybe in this situation, even though the firmAos capital stocks are high, but the costs to acquire the capital are greater. Therefore, an increase in firmAos capital stock decreases the firmAos investments. Conclusions The purpose of this paper is twofold: to show how credit market imperfections have been incorporated to dynamic general equilibrium models of the economy, using recent advances in the economics of information and and to provide an empirical evidence for investment equation. The following conclusions can be extracted from the study realized in this paper: first, theoretically, agency costs arising from asymmetric information raise the cost of external finance, and therefore discourage investment. This result suggests that the efficiency of the Ismail & Sanusi AiAn Empirical Analysis of Cash Flow and Investment Fluctuations . financial system in processing information and monitoring borrowers is a potentially important determinant of This observation has implications for both short-run fluctuations and long-run growth. Second, the empirical studies of firm investment provide strong support for the basic predictions of links between changes in net worth and investment arising from informational problems in financial markets. For many firms in the economy, the evidence is consistent with: a gap between the cost of external and internal and a positive relationship between the borrowerAos spending and net worth. Therefore, we should examine not only with respect to investment in plant and equipment spending, but also in inventory investment, research and development, employment, business formation and survival, pricing, and corporate risk management. Third, credit market imperfections create two new channels through which monetary policy can affect the investment decisions of the agents in the economy: the balance sheet and the bank lending channels. Fourth, while there is relatively an agreement on the role of financial frictions in the investment decisions of some firms, there is less agreement on the magnitude of that role. Several possible extensions of this line of research: analyze the link between internal resources and the shadow cost of external financing in models of decisions in individual firms and industries. and estimate the quantitative importance of the financial accelerator for aggregate investment fluctuations.
