financial markets and growth the last five years have witnessed a resurgence of interest in the relationship between financial intermediation and economic growth this issue had been extensively studied nearly two decades earlier by goldsmith 1969 mckinnon 1973 shaw 1973 and others who produced considerable evidence that financial development correlates with growth but their work though insightful lacked analytical foundations in traditional growth theory financial intermediation could be related to the level of the capital stock per worker or to the level of productivity but not to their respective growth rates the latter were ascribed to exogenous technical progress the recent revival of interest in the link between financial development and growth stems mainly from the insights and techniques of endogenous growth models which have shown that there can be self sustaining growth without exogenous technical progress and that the growth rate can be related to preferences technology income distribution and institutional arrangements this provides the theoretical underpinning that early contributors lacked tinancial intermediation can be shown to have not only level effects but also growth effects the resulting models have offered important insights into the effect of financial development on growth and vice versa they have also provided new impetus to empirical research on these issues this paper reviews the ground covered so far on the theoretical and empirical front and points to some still unresolved issues

investment financing decisions and tax policy mists have analyzed the effects of taxes on capital spending most studies assume that firms respond to prices set in centralized securities markets such as market interest rates of tobin s q and firms undertake all profitable investment projects firms choose the mix or finance among internal funds debt and new equity independently the availability of finance does not limit investment the implications for tax policy are clear the marginal tax rate on returns from a new project matters for investment not the firm s average tax burden on returns from its investments in place for firms that face imperfect markets for

on the role of government in a stochastically growing open economy abstract the relationship between the size of government economic growth and volatility in a small open economy is analyzed first we characterize the stochastic equilibrium for a centrally planned economy contrasting it with a closed economy the role of government consumption expenditure both as a stabilizing and a destabilizing factor is discussed the optimal size of government is derived and we find that an open economy will have a larger government if and only if it is a net creditor second the stochastic equilibrium in a decentralized economy is characterized and the optimal tax structure derived finally the role of government production expenditure and its impact on risk is briefly discussed

the quality effect does financial liberalization improve the allocation of capital abstract we document evidence of a quality effect of financial liberalization on allocative efficiency as measured by dispersion in tobin s q across firms we predict that financial liberalization by equalizing access to credit is associated with reduced variation in expected marginal returns we test this prediction using a new financial liberalization index and firm level data for five emerging markets india jordan korea malaysia and thailand we find robust evidence that financial liberalization rather than financial deepening is associated with improved allocative efficiency

financial intermediation and endogenous growth an endogenous growth model with multiple assets is developed agents who face random future liquidity needs accumulate capital and a liquid but unproductive asset the effects of introducing financial intermediation into this environment are considered conditions are provided under which the introduction of intermediaries shifts the composition of savings toward capital causing intermediation to be growth promoting in addition intermediaries generally reduce socially unnecessary capital liquidation again tending to promote growth

military spending and stochastic growth abstract this study examines capital accumulation military spending arms accumulation and output growth in a stochastic endogenous growth model the analysis shows that higher lower growth in foreign military spending leads to faster slower economic growth in the home country if the home country s intertemporal substitution elasticity in consumption is smaller larger but more volatility in foreign military spending can lead to higher economic growth in the home country when its intertemporal substitution elasticity is large in addition shocks to output production may stimulate economic growth

economies of scale and barriers to entry dixit has recently presented a model in which established firms select capacity to discourage entry but cannot employ threats they would not rationally execute after entry entry deterrence in a slight modification of this model involves the classical limit price output under linear or concave demand however the capital cost of a firm of minimum efficient scale is an upper bound on the present value of the monopoly profit stream that can be shielded from entry it is argued that this suggests the general unimportance of entry barriers erected by scale economies

non linearity between finance and growth abstract we present a simple model which establishes a non linear and possibly non monotonic relationship between financial development and economic growth applying a threshold regression model to king and levine s q j econ 109 1993 83 data set we find evidence consistent with the theoretical model

price discrimination in cournot competition abstract we examine the average equilibrium price when quantity setting oligopolies price discriminate it is known that for the price discrimination extension of cournot competition the average price is independent of the extent of price discrimination whenever the demand is linear we show that this result holds under a larger class of demand functions

the impact of capital market imperfections on investment cash flow sensitivity abstract we examine the investment cash flow sensitivity of us manufacturing firms in relation to five factors associated with capital market imperfections fund flows institutional ownership analyst following bond ratings and an index of antitakeover amendments we find a steady decline in the estimated sensitivity over time furthermore we find that investment cash flow sensitivity decreases with increasing fund flows institutional ownership analyst following antitakeover amendments and with the existence of a bond rating the overall evidence suggests that investment cash flow sensitivity decreases with factors that reduce capital market imperfections

same financial development yet different economic growth why we re study the relationship between financial development and real gdp per capita growth in 48 countries what we find is an interesting evidence that only stock market development has positive effects on growth and that banking development has an unfavorable if not negative effect on growth we examine whether or not these impacts are a product of various financial and economic conditional variables our conditional variables consist of financial liberalization two sets of country development dummies crises in banking and currency dummies the creditor protection index as well as the anti director and corruption indices our results clearly show that the conditional variables of financial liberalization high income level and good shareholder protection mitigate the negative impacts of banking development on growth in contrast the conditional variables of middle income level regional latin american sub saharan african and east asian dummies banking and currency crises good creditor protection and higher corruption strengthen the negative impacts of banking development on growth next the conditional variables of middle income level latin american sub saharan african and east asian dummies strengthen the positive impacts of stock market development on growth whereas the conditional variables of financial liberalization mitigate the positive impacts of stock market development on growth last we find that the relationship between growth and bank development is better described as a weak inverse ushape this inverse u shape becomes stronger when additional stock market variables are squared thus financial development and growth may in fact be in a nonlinear form

commodity trade and international risk sharing how much do financial markets matter abstract this paper evaluates the social gains from international risk sharing in some simple general equilibrium models with output uncertainty a simulation model calibrated to selected moments of u s and japanese data estimates the incremental loss from a ban on international portfolio diversification to be on the order of 0 20 percent of output per year even the theoretical gains from asset trade may disappear under alternative sets of assumptions on preferences and technology the paper argues that the small magnitude of potential trade gains may help explain the apparently inconsistent findings of empirical studies on the degree of international capital mobility

a closed form solution for a model of precautionary saving this paper analyses life cycle consumption plans and distinguishes between temporal risk aversion and intertemporal substitution the results assume that felicity functions are quadratic and that income follows a linear model with normally distributed errors stochastic dynamic programming then yields closed loop linear decision rules certainty equivalence no longer holds but instead households play a min max strategy against nature one finds a rationale for precautionary saving and a larger sensitivity of changes in consumption to income innovations

on dynamic linkages of the state natural gas markets in the usa evidence from an empirical spatio temporal network quantile analysis we empirically investigate the dynamic linkages of the state level natural gas markets in the usa by introducing a novel spatio temporal network quantile econometric model we can estimate the dynamic cross state dependency or market integration of the state level natural gas markets and the dependence of the state natural gas markets on the national crude oil market at different quantile levels we find that significant local dynamic neighbouring market integrations exist in the natural gas markets not only in the eastern and central states as evidenced in the literature but also in some western and southwest states our results also show that there are significant linkages of the state level natural gas markets to the national crude oil market through the lagged price shocks and the long run price equilibrium with the national gas markets under varying price shock propagations the results can help local government and energy users to mitigate the negative impacts from the expected or unexpected fluctuations in the oil and the neighbouring natural gas markets which will enact appropriate state level price discovery and energy policy and investment decision makings

the precious bane abstract are natural resources harmful to growth we address this question using a two sector endogenous growth model in which human capital is the engine of growth by increasing the rewards to unskilled labor natural resources make schooling more expensive as long as the intertemporal elasticity of consumption substitution is not too high this slows down human capital accumulation and growth the presence of production spillovers from human capital however implies that a planner could react to a resource boom by increasing human capital accumulation even though the decentralized solution yields the exact opposite the paper also shows that as the production complementarity between natural resources and unskilled labor declines the growth effects of natural resources become increasingly sensitive to whether or not there is free trade in goods the empirical evidence lends support to the main channel natural resources to human capital to growth that is suggested in the paper

welfare gains from financial liberalization financial liberalization has been a controversial issue as empirical evidence for growth enhancing effects is mixed here we find sizable welfare gains from liberalization cost to repression though the gain in economic growth is ambiguous we take the view that financial liberalization is a government policy that alters the path of financial deepening while financial deepening is endogenously chosen by agents given a policy and occurs in transition towards a distant steady state this history dependent view necessitates the use of simulation analysis based on a growth model our application is a specific episode thailand from 1976 to 1996

another perspective on gasoline price responses to crude oil price changes the effects of oil price volatility on the responses of gasoline prices to oil price shocks have received little attention in discussions on the relationship between the prices of crude oil and gasoline in this paper we consider such effects by using a bivariate structural vector autoregression which is modified to accommodate garch in mean errors our measure of oil price volatility is the conditional variance of the oil price change forecast error we isolate the effects of volatility in the price of oil on the price of gasoline and employ simulation methods to calculate nonlinear impulse response functions nirfs to trace any asymmetric effects of independent oil price shocks on the conditional means of gasoline prices we test whether the relationship between the prices of crude oil and gasoline is symmetric using tests of the null hypothesis of symmetric impulse responses based on monthly u s data over the period from 1978 1 to 2014 11 our empirical results show that gasoline prices respond asymmetrically to positive and negative oil price shocks we also find that oil price volatility has a positive effect on the price of gasoline and it contributes to the asymmetries in the transmission of oil price shocks

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

prices rise faster than they fall output prices tend to respond faster to input increases than to decreases this tendency is found in more than two of every three markets examined it is found as frequently in producer goods markets as in consumer goods markets in both kinds of markets the asymmetric response to cost shocks is substantial and durable on average the immediate response to a positive cost shock is at least twice the response to a negative shock and that difference is sustained for at least five to eight months unlike past studies which documented similar asymmetries in selected markets gasoline agricultural products etc this one uses large samples of diverse products 77 consumer and 165 producer goods accordingly the results suggest a gap in an essential part of economic theory as a start on filling this gap the study finds no asymmetry in the resonse of an individual decision maker a supermarket chain to its costs but it finds above average asymmetry where a cost shock is filtered through a fragmented w

dependence and extreme dependence of crude oil and natural gas prices with applications to risk management abstract in this article we show how the copula garch approach can be appropriately used to investigate the conditional dependence structure between the crude oil and natural gas markets as well as to derive implications for portfolio risk management in extreme economic conditions using daily price data from january 1997 to october 2011 our in sample results show evidence of asymmetric dependence between the two markets the crude oil and gas markets tend to comove closely together during bullish periods but not at all during bearish periods moreover taking the extreme comovement into account leads to an improvement in the accuracy of the out of sample value at risk forecasts

oil and pump prices testing their asymmetric relationship in a robust way abstract the aim of this study is to provide a novel method to assess whether retail fuel prices respond asymmetrically to changes in the international crude oil prices to do so we consider the whole supply chain we use daily data and we depart from the current practice in the literature that focuses on prices rather we consider the mark ups of both the refineries and retailers hence we show that we first need to assess whether the refineries mark up responds asymmetrically to the international crude oil prices and subsequently whether the retailers mark up shows an asymmetric behaviour relatively to changes in the refined fuel prices focusing in greece as our case study our findings show that greek fuel retailers do not change their mark up behaviour based on changes of the refined fuel price by contrast the asymmetric behaviour is evident in the refineries mark up relatively to changes in the international crude oil prices which is then passed through to the retailers and consumers finally we provide evidence that weekly and monthly data mask any such asymmetric relationship thus we maintain that unless the appropriate data frequency fuel price transformations and the whole supply chain are considered misleading findings could be revealed

directed credit financial development and financial structure theory and evidence the recent initiative of the rbi in reviving the policy of directed credit allocation in a period dominated by the neoliberal philosophy necessitates reconsideration of the role of policy directed

price discrimination and social welfare studies the effect of price discrimination on social welfare using methods from duality theory features of the reservation model presented quasi linear utility and consumers surplus upper and lower bounds on welfare change bounds on welfare change with optimal price discrimination from ebsco

asymmetric and nonlinear pass through of crude oil prices to gasoline and natural gas prices in this article we use the recently developed nonlinear autoregressive distributedlags nardl model to examine the pass through of crude oil prices into gasoline and natural gas prices our approach allowsus to simultaneously test the short and long run nonlinearities through positive and negative partial sum decompositions of the predetermined explanatory variables it also offers the possibility to quantify the respective responses of gasoline and natural gas prices to positive and negative oil price shocks from the asymmetric dynamic multipliers the obtained results indicate that oil prices affect gasoline prices and natural gas prices in an asymmetric and nonlinear manner but the price transmission mechanism is not the same important policy implications can be learned from the empirical findings

the implications of knowledge based growth for the optimality of open capital markets this paper re examines the view that opening capital markets must have long run benefits the analysis shows that the desirability of opening a country s capital markets depends on the nature of the technology assumed models of knowledge based growth predict that changes that alter the economy s level of production will also affect the economy s growth rate and hence the welfare of future generations standard neoclassical growth models imply no such effects on growth or welfare if production does involve an important element of learning by doing inference from the standard models may be seriously misleading in particular opening capital markets does not necessarily improve welfare for the nation or for the world as a whole

growth and risk sharing with private information abstract we examine the impact of incomplete risk sharing on growth and welfare the source of market incompleteness in our economy is private information a household s idiosyncratic productivity shock is not observable by others risk sharing between households occurs through long term contracts with intermediaries we find that incomplete risk sharing tends to reduce the rate of growth relative to the complete risk sharing benchmark numerical examples indicate that the welfare cost and the growth effect of private information are small

another look on the relationships between oil prices and energy prices this paper employs the quantile autoregressive distributed lags qardl model developed recently by cho et al 2015 to investigate the pass through of oil prices to a set of energy prices this approach allows analyzing simultaneously short term connections and long run cointegrating relationships across a range of quantiles it also provides insights on the short run predictive power of oil prices in predicting energy prices while accounting for the cointegration between oil prices and each of the considered energy prices in low medium and high quantiles two key findings emerge from this paper first all considered energy prices are shown to be cointegrated with oil price across quantiles meaning that a stationaryequilibriumrelationship exists between single energy price and oil price second we find evidence that oil price is a significant predictor of individual petroleum products prices and natural gas in the short run this paper has important policy implications for forecasters energy policy makers and portfolio managers

equity markets and growth cross country evidence on timing and outcomes 1980 1995 abstract the rapid expansion of organized equity exchanges in both emerging and developed markets has prompted policymakers to raise important questions about their macroeconomic impact yet the need to focus on recent data poses implementation difficulties for econometric studies of dynamic interactions between stock markets and economic performance in individual countries this paper overcomes some of these difficulties by applying recent developments in the analysis of panels with a small time dimension to estimate vector autoregressions for a set of 47 countries with annual data for 1980 1995 after describing recent theories on the role of stock markets in growth and considering a pure cross sectional empirical approach our panel vars show leading roles for stock market liquidity and the intensity of activity in traditional financial intermediaries on per capita output the findings underscore the potential gains associated with developing deep and liquid financial markets in an increasingly global economy

output growth the real wage and employment fluctuations this paper is an attempt to contribute to the integration of business cycle analysis with long term growth a real business cycle model with endogenous growth is developed and estimated with u s data in the present framework wage movements do not have to be transitory to generate fluctuations in labor effort the reduced form is a constrained bivariate output hours or real wage hours vector autoregressive process the bivariate setup provides a useful framework for analyzing the persistence of output fluctuations given that the theory implies that hours of work contain information about future output movement copyright 1991 by american economic association

a threshold cointegration analysis of asymmetric price transmission from crude oil to gasoline prices abstract this study provides new supportive evidence for asymmetric adjustment in u s retail gasoline prices the asymmetric transmission is found to occur not just through the spot markets of crude oil and refinery gasoline but also through their future markets further evidence also shows that the observed asymmetry in price transmission primarily occurs downstream not upstream of the transmission process

financial integration and growth in a risky world abstract we revisit the debate on the benefits of financial integration in a two country neoclassical growth model with aggregate uncertainty the framework accounts simultaneously for gains from a more efficient capital allocation and gains from risk sharing together with their interaction global numerical methods allow for meaningful welfare comparisons gains from integration are quantitatively small even for riskier and capital scarce emerging economies these countries import capital for efficiency reasons before exporting it for self insurance leading to capital flows and growth reversals along the transition this opens the door to richer empirical implications than previously considered in the literature

output and welfare effects of optimal price discrimination in markets segmented at the initiative of the seller abstract this paper investigates the output and welfare effects of optimal price discrimination in markets segmented at the initiative of the seller a market with n segments and prices is compared to a noncooperative cournot nash oligopoly with n competitors output and welfare are greater than less than equal to cournot nash levels when the demand function is concave convex linear from below

habit persistence and welfare gains from international asset trade we introduce habit formation in a model that studies the link between international trade in financial assets economic growth and welfare as with time separable preferences asset trade increases the mean growth rate but it also increases growth volatility we demonstrate that the welfare gain from asset trade is lower with habit persistence in consumption this reflects that the habit forming households perceive the higher growth volatility as a higher cost to obtain increased average growth calibrating the model to data for north america and western europe we find that habit persistence lowers welfare gains of financial integration by about 40 50

human capital risk and economic growth this paper develops a tractable incomplete markets model of economic growth in which households invest in risk free physical capital and risky human capital the paper shows that a reduction in uninsurable idiosyncratic labor income risk decreases physical capital investment but increases human capital investment growth and welfare a quantitative analysis based on a calibrated version of the model reveals that these effects are substantial and of the same order of magnitude as the effects of distortionary income taxation the analysis further suggests that government sponsored severance payments to displaced workers increase growth and welfare even if these payments have to be e nanced through distortionary income taxation

financial development growth and the distribution of income a paradigm is presented in which both the extent of financial intermediation and the rate of economic growth are endogenously determined financial intermediation promotes growth because it allows a higher rate of return to be earned on capital and growth in turn provides the means to implement costly financial structures thus financial intermediation and economic growth are inextricably linked in accord with the goldsmith mckinnon shaw view on economic development the model also generates a development cycle reminiscent of the kuznet hypothesis in particular in the transition from a primitive slow growing economy to a developed fast growing one a nation passes through a stage in which the distribution of wealth across the rich and poor widens

quality uncertainty and guarantee this paper presents a monopoly model with product quality uncertainty in which optional quality guarantee is used to effectively segment the monopolist s potential market and price discriminate among consumers having different incomes the optional guarantee pricing is seen to dominate pure monopoly pricing either with tied in guarantee or no guarantee in terms of maximum expected profits in the optional guarantee equilibrium the monopolist captures a larger part of his potential market by charging a lower price for an unguaranteed product and a higher price for a guaranteed product than does either of the pure monopoly solutions

the effect of financial liberalization on the capital structure and investment decisions of indonesian manufacturing establishments this article analyzes the consequences of financial liberalization using a large panel of indonesian manufacturing establishments it discusses whether financial reforms have had an impact on investment and on the allocation of credit and whether the effects differ depending on the type of firms the overall conclusion is that shifting from administrative toward market based allocation of credit has increased borrowing cost particularly for smaller firms but at the same time has benefited firms by giving them widened access to finance

international risk sharing and economic growth international risk sharing which diversifies away income risk will reduce saving with constant relative risk aversion if growth arises from the external effects of human capital accumulation then reducing saving will reduce growth welfare also may fall with risk sharing because endogenous growth with external effects of capital accumulation typically implies a competitive equilibrium growth rate already less than the optimal growth rate we demonstrate these results in a standard representative agent economy diversifying away rate of return risk also will reduce saving and growth rates if relative risk aversion exceeds one but this diversification always increases welfare this paper studies the effects of international risk sharing portfolio diversification in a world economy in which growth rates of income are endogenous growth is based upon the spillover effects of human capital accumulation as in lucas 1988 and romer 1986 there are positive economy wide spillovers of human capital intensity on individual labour productivity in section 2 we construct a multi country growth model with an infinitely lived representative agent in each country each country faces income risk but there is no aggregate uncertainty at the world level we focus on two market structures in the first structure there are no markets which allow for international diversification of country specific income risk in the second structure there are complete international markets for risksharing with no aggregate world uncertainty this completeness allows full diversification of country specific risk the paper has two central results first growth rates in all countries are lower in the equilibrium with full diversification second in this same structure welfare of each country may be lower than in an equilibrium without risk sharing the reasoning is as follows with external effects of capital accumulation the compet

asymmetry in retail gasoline and crude oil price movements in the united states an application of hidden cointegration technique abstract there is a common belief that gasoline prices respond more quickly to crude oil price increases than decreases some economists and politicians believe that asymmetry in oil and gasoline price movements is the outcome of a non competitive gasoline market requiring that governments take policy action to address unfair pricing there is no consensus as to the existence or nature of the asymmetric relationship between prices of gasoline and crude oil much of this literature specifies asymmetry in the speed of adjustment and short run adjustment coefficients in contrast granger and yoon s granger c w and yoon g hidden cointegration university of california san diego department of economics working paper 2002 crouching error correction model cecm identifies asymmetry of the cointegrating vectors between components cumulative positive and negative changes of the series applying the cecm to retail gasoline and crude oil prices for the u s we find that there is only evidence of cointegration between positive components of crude oil prices and negative components of gasoline prices in contrast to the literature which attributes asymmetric price movements to market power of refiners these findings suggest that gasoline prices in the long run are more influenced by the technological changes on the demand side than crude oil price movements on the supply side

capital market imperfections and financialization of real sectors in emerging markets private investment and cash flow relationship revisited summary the paper analyzes the impacts of cash flow from multiple investments in real and financial sectors on the new fixed investment spending of real sector firms the empirical results based on the euler equation approach and semi annual firm level data from two major emerging markets mexico and turkey suggest that profits and rates of returns from fixed and financial assets have differential effects on fixed investment spending of real sector firms accordingly increasing availability and accessibility of alternative investment opportunities in financial markets can become instrumental in channeling real sector savings to short term financial investments instead of long term fixed capital formation and thus lead to deindustrialization

econometric models of asymmetric price transmission abstract in this paper we review the existing empirical literature on price asymmetries in commodities providing a way to classify and compare different studies that are highly heterogeneous in terms of econometric models type of asymmetries and empirical findings relative to the previous literature this paper is novel in several respects first it presents a detailed and updated survey of the existing empirical contributions on price asymmetries in the transmission mechanism linking input prices to output prices second this paper presents an extension of the traditional distinction between long run and short run asymmetries to new categories of asymmetries such as contemporaneous impact distributed lag effect cumulated impact reaction time equilibrium and momentum equilibrium adjustment path regime effect regime equilibrium adjustment path each empirical study is then critically discussed in the light of this new classification of asymmetries third this paper evaluates the relative merits of the most popular econometric models for price asymmetries namely autoregressive distributed lags partial adjustments error correction models regime switching and vector autoregressive models finally we use the meta regression analysis to investigate whether the results of asymmetry tests are not model invariant and find which additional factors systematically influence the rejection of the null hypothesis of symmetric price adjustment the main results of our survey can be summarized as follows i each econometric model is specialized to capture a subset of asymmetries ii each asymmetry is better investigated by a subset of econometric models iii the general significance of the f test for asymmetric price transmission depends mainly on characteristics of the data dynamic specification of the econometric model and market characteristics overall our empirical findings confirm that asymmetry in all its forms is very likely to occur in a wide range of markets and econometric models

new evidence on asymmetric gasoline price responses in a 1997 paper borenstein cameron and gilbert bcg claim that gasoline prices rise quickly following an increase in the price of crude oil but fall slowly following a decrease this note estimates an error correction model with daily spot gasoline and crude oil price data over the period 1985 1998 and finds no evidence of asymmetry in wholesale gasoline prices the sources of the difference in results are twofold first we use the standard engle granger two step estimation procedure whereas bcg used a nonstandard estimation methodology second even using bcg s nonstandard specification the use of daily rather than weekly data yields little evidence of price asymmetry

consumption puzzles and precautionary savings abstract when marginal utility is convex agents accumulate savings as a precautionary measure against labor income eventualities this paper shows that precautionary savings can go a long way in making the excess growth excess smoothness and excess sensitivity features of consumption consistent with the stochastic processes of labor income observed in the u s at the microeconomic level

the impact of negative cash flow and influential observations on investment cash flow sensitivity estimates abstract kaplan and zingales quart j econ 112 1997 169 and clearly j finance 54 2 1999 673 diverge from the large literature on investment cash flow sensitivity by showing that investment is most sensitive to cash flow for the least financially constrained firms we examine if this result can be explained by the fact that when firms are in sufficiently bad shape incurring cash losses investment cannot respond to cash flow we find that while cleary s results can be explained by such negative cash flow observations the kaplan zingales results are driven more by a few influential observations in a small sample we also record a decline in investment cash flow sensitivity over the 1977 1996 period particularly for the most constrained firms

oil price fluctuation volatility spillover and the ghanaian equity market implication for portfolio management and hedging effectiveness abstract this study attempts to contribute to the literature on stock markets and energy prices by examining the dynamic volatility and volatility transmission between oil and ghanaian stock market returns in a multivariate setting using the recently developed var garch var agarch and dcc garch frameworks in turn the models results are used to compute and analyze the optimal weights and hedge ratios for oil stock portfolio holdings for comparison purposes and to put the paper more in the perspective of west africa the nigerian stock market is also included in the analysis our findings point to the existence of significant volatility spillover and interdependence between oil and the two stock market returns while spillover effects are stronger for nigeria the transmission of volatility is much more apparent from oil to stock than from stock to oil in the case of ghana also the study demonstrates evidence of short term predictability in oil and stock price changes through time and reveals that conditional volatility changes more rapidly as result of substantial effects of past volatility rather than past news shocks for all market returns moreover we show that there is a slightly more effective hedge in the two stock markets under the dcc garch framework our preferred model compared to the other two models although hedging effectiveness is much greater for ghana on the whole our findings for optimal hedge ratios are consistent with other studies and particularly the view that oil assets should be an integral part of a diversified portfolio of stocks and suggest that a better understanding of volatility links is crucial for portfolio management in the presence of oil price risk finally the existence of multivariate asymmetric effects and dynamic conditional correlations as revealed by the var agarch and dcc garch models make it clear that the assumptions of symmetric effects and constant conditional correlations are not supported empirically

capital market imperfections before and after financial liberalization an euler equation approach to panel data for ecuadorian firms using a large set of panel data for ecuadorian firms the authors analyze the role of capital market imperfections in investment decisions and investigate whether the financial reforms introduced in the 1980s in ecuador succeeded in relaxing financial constraints to facilitate capital accumulation and growth the ecuadorian government removed administrative controls on the interest rate and eliminated or scaled down directed credit programs the model used here allows both for an increasing cost of borrowing as the degree of leverage increases and for a ceiling on leverage the econometric results suggest that both types of capital market imperfections are important for small and young firms but not for large and old firms moreover the estimated equations do not provide evidence that financial reform in ecuador has helped to relax these financial constraints

capital control liberalization and stock market development the authors address two questions what happens to stock market size liquidity volatility and integration with world capital markets after capital controls are liberalized and what is the relationship between those indicators of stock market development and regulations about information disclosure accounting standards and investor protection an analysis of data on stock markets in 16 developing countries suggests the following a stock markets become larger more liquid more integrated internationally and more volatile after controls on capital and dividend flows are liberalized b easy access to information about firms is positively associated with the size and liquidity of stock markets and c countries that officially establish internationally accepted accounting standards and laws to protect investors do not have substantially better functioning stock markets than countries that do not adopt those official standards

financial liberalization credit constraints and collateral investment in the mexican manufacturing sector abstract we examine the impact of financial liberalization on fixed investment in mexico using establishment level data from the manufacturing sector in addition to analyzing changes in cash flow sensitivities an innovative approach explores the role of real estate as collateral and addresses a potential censoring problem the results suggest that financial constraints were eased for the smallest firms but not for larger ones however the importance of possessing real estate increased given banks reliance on collateral in their lending the results also provide microeconomic evidence consistent with the role attributed to financial accelerator mechanisms during lending booms and during post crisis recessions

cyclical uncertainty precautionary saving and economic growth this paper studies the interaction between cyclical uncertainty precautionary saving and economic growth in a stochastic endogenous growth model the analysis provides insight into the potential connection between technological uncertainty of the sort popularized in real business cycle models and the determinants of economic growth in a stochastic version of a popular model of endogenously determined economic growth the magnitude of the link between cyclical uncertainty and growth is quantified and found to be small in terms of its effect on the growth rate but possibly large in terms of its effect on levels of macroeconomic variables moreover the welfare costs of reduced cyclical uncertainty can be substantial owing to the lower historical rate of capital accumulation induced by a decrease in precautionary saving the chief implications of the model are found to be roughly consistent with the postwar experience of several countries although the predictions of the model with regard to growth rates are too small to explain much of the variation in growth rates across time or across countries

idiosyncratic production risk growth and the business cycle we introduce a neoclassical growth economy with idiosyncratic production risk and incomplete markets each agent is an entrepreneur operating her own technology with her own capital stock the general equilibrium is characterized by a closed form recursion in the cara normal case incomplete markets introduce a risk premium on private equity which reduces the demand for investment as compared to complete markets the steady state can thus have both a lower capital stock due to investment risk and a lower interest rate due to precautionary savings furthermore the anticipation of high real interest rates in the future feeds back into high risk premia and low investment in the present thus slowing down convergence to the steady state our results highlight the importance of private risk premia for capital accumulation and business cycles

the welfare effect of international asset market integration under nominal rigidities abstract this paper assesses the impact of integrating international asset markets when segmented markets are not the only distortion using a two country general equilibrium model with nominal rigidities and monetary shocks we show that integration is not universally beneficial instead the welfare impact depends on the degree to which exchange rate fluctuations are passed through to consumer prices while the integration is welfare neutral in the polar cases of complete or zero pass through this is not the case when pass through is partial when shocks are equally volatile in both countries integration can be detrimental or beneficial depending on the degree of pass through when shocks are more volatile in one country it benefits from integration compared with the more stable country

the message in north american energy prices how similar is the price behavior of north american natural gas fuel oil and power prices using current state of the art econometric methodology we explore the degree of shared trends across north american energy markets across these markets there appear to be effective arbitraging mechanisms for the price of natural gas and fuel oil but not for the price of electricity

investor protection optimal incentives and economic growth does investor protection foster economic growth to assess the widely held affirmative view we introduce investor protection into a standard overlapping generations model of capital accumulation better investor protection implies better risk sharing because of entrepreneurs risk aversion this results in a larger demand for capital this is the demand effect a second effect the supply effect follows from general equilibrium restrictions better protection i e higher demand increases the interest rate and lowers the income of entrepreneurs decreasing current savings and next period s supply of capital the supply effect is stronger the tighter are the restrictions on capital flows our model thus predicts that the positive effect of investor protection on growth is stronger for countries with lower restrictions cross country data provide support for this prediction as does the detailed examination of the growth experiences of south korea and india

financial markets in development and the development of financial markets what is the relationship between markets and development it is argued that markets promote growth and that growth in turn encourages the formation of markets two models with endogenous market formation are presented to analyze this issue the first examines the role that financial markets banks and stock markets play in allocating funds to the highest valued use in the economic system it is shown that intermediation will arise under weak conditions the second focuses on the role that markets play in supporting specialization in economic activity the consequences of perfect competition in market formation are highlighted

precautionary saving in the small and in the large the theory of precautionary saving is shown to be isomorphic to the arrow pratt theory of risk aversion making possible the application of a large body of knowledge about risk aversion to precautionary saving and more generally to the theory of optimal choice under risk in particular a measure of the strength of the precautionary saving motive analogous to the arrow pratt measure of risk aversion is used to establish a number of new propositions about precautionary saving and to give a new interpretation of the dreze modigliani substitution effect copyright 1990 by the econometric society

do gasoline prices respond asymmetrically to crude oil price changes the authors test and confirm that retail gasoline prices respond more quickly to increases than to decreases in crude oil prices among the possible sources of this asymmetry are production inventory adjustment lags and market power of some sellers by analyzing price transmission at different points in the distribution chain the authors attempt to shed light on these theories spot prices for generic gasoline show asymmetry in responding to crude oil price changes which may reflect inventory adjustment effects asymmetry also appears in the response of retail prices to wholesale price changes possibly indicating short run market power among retailers

oil and the macroeconomy when prices go up and down an extension of hamilton s results in an important paper hamilton 1983 demonstrated a strong correlation between oil price changes and gross national product growth in u s data however his study pertained to a period in which all the large oil price movements were upward and thus it left unanswered the question whether the correlation persists in periods of price decline moreover the price variable he used was somewhat distorted by price controls in the 1970s this note investigates whether hamilton s results continue to hold when the sample is extended to include the recent oil market collapse and the oil price variable is corrected for the effects of price controls particular attention is given to the possibility of asymmetric responses to oil price increases and decreases as suggested in the structural employment literature loungani 1986 davis 1987 hamilton 1988 like hamilton i based my investigation on the gnp equation in sims s 1 980b six variable quarterly vector autoregressive model
