complexity in structured finance we study complexity in the market for securitized products a market at the heart of the financial crisis of 2007 9 the complexity of these products rose substantially in the years preceding the financial crisis we find that securities in more complex deals default more and have lower realized returns the worse performance is economically meaningful a one standard deviation increase in complexity represents an 18 increase in default on aaa securities however yields of more complex securities are not higher indicating that investors did not perceive them as riskier our results are consistent with complexity obfuscating security quality

value of information in competitive economies with incomplete markets we study the value of public information in competitive economies with incomplete markets we show that generically the welfare effect of a change in the information available prior to trading can be in any direction there exist changes in information that make all agents better off and changes for which all agents are worse off in contrast for any change in information a pareto improvement is feasible that is attainable by a planner facing the same informational and asset market constraints as agents in this sense the response of competitive markets to changes in information is typically not socially optimal

informed trading investment and welfare this article studies the welfare economics of informed stock market trading we analyze the effect of more informative prices on investment given that this dependence will itself be reflected in equilibrium prices while a higher incidence of informed speculation always increases firm value through a more informative trading process the effect on agents welfare depends on how revelation of information changes risk sharing opportunities in the market greater revelation of information that agents wish to insure against reduces their hedging opportunities on the other hand early revelation of information that is uncorrelated with hedging needs allows agents to construct better hedges

the demand for money in developing countries assessing the role of financial innovation traditional specifications of money demand have commonly been plagued by persistent overprediction implausible parameter estimates and highly autocorrelated errors the authors argue that some of these problems stem from the failure to account for the impact of financial innovation they estimate money demand for ten developing countries using various proxies for financial innovations they also assess the relative importance of this variable finding financial innovation can be better modeled as a stochastic random walk trend rather than a deterministic time trend financial innovation plays an important role in determining fluctuations of the demand for money the importance of this role increases with the rate of inflation

the possibility of informationally efficient markets abstract a rational expectations equilibrium with positive demand for financial information does exist under fully revealing asset price contrary to a wide held conjecture whereas a continuum of investors is inconsistent with fully revealing equilibrium finitely many investors with average portfolios demand information in equilibrium if they can adjust portfolio size in an additive signal return model more information diminishes the expected excess return of a risky asset so that investors who only have a choice of portfolio composition or whose asset endowments strongly differ from the average portfolio are worse off under fully revealing price information market equilibria both with and without information acquisition are pareto efficient

a liquidity based model of security design we consider the problem of the design and sale of a security backed by specified assets given access to higher return investments the issuer has an incentive to raise capital by securitizing part of these assets at the time the security is issued the issuer s or underwriter s private information regarding the payoff of the security may cause illiquidity in the form of a downward sloping demand curve for the security the severity of this illiquidity depends upon the sensitivity of the value of the issued security to the issuer s private information thus the security design problem involves a tradeoff between the retention cost of holding cash flows not included in the security design and the liquidity cost of including the cash flows and making the security design more sensitive to the issuer s private information we characterize the optimal security design in several cases we also demonstrate circumstances under which standard debt is optimal and show that the riskiness of the debt is increasing in the issuer s retention costs for assets

financial innovation and information the role of derivatives when a market for information exists we study the effects of financial innovation in a model of endogenous information acquisition we determine the conditions under which the introduction of a derivative written on an existing stock increases or decreases the incentive to purchase information we show that financial innovation produces some effects which hold across informational structures and others which differ the former coincide with the few empirical results that are robust in the literature effects on prices risk premia and volatility while the latter coincide with the ones that differ experiment by experiment effects on volume correlation between volume and volatility and market informational efficiency copyright 2002 oxford university press

excess demand functions when new assets are introduced abstract we demonstrate that information on the aggregate excess demand function of an incomplete real asset market economy is not helpful toward predicting the equilibrium of a new economy to which unredundant assets are added an innovation of assets can completely change the aggregate excess demand functions

gains from trade in a social choice context we ask whether there exists a rule in which nobody loses under trade liberalization we consider a resource allocation problem in which the traded commodities vary we propose an axiom stating that enlarging the set of tradable commodities hurts nobody we show that if a rule satisfies this axiom together with an allocative efficiency axiom and an institutional constraint axiom stating that only preferences over tradable commodities matter gains from trade can be given to only one individual in the first step of liberalization

welfare improving asymmetric information in dynamic insurance markets this article presents a two period asymmetric learning model of insurance markets when information about past accidents is not shared by insurers asymmetries of information develop through time equilibrium contracts exist are payoff unique and display a realistic bonus malus pattern eliminating asymmetries through information sharing is welfare decreasing in contrast with past contributions on insurance and adverse selection when second period contract offers cannot be contingent on initial contract choice a strict increase in welfare is obtained through menus of contracts although initial contract choice is in itself worthless information

a theory of trading volume a theory of trading volume is developed based on assumptions that market agents frequently revise their demand prices and randomly encounter potential trading partners the model describes two distinct ways informational events affect trading volume one is consistent with conjectures made by empirical researchers that investor disagreement leads to increased trading but the observation of abnormal trading volume does not necessarily imply disagreement and volume can increase even if investors interpret the information identically if they also have had divergent prior expectations simulation tests support the model and are used to contrast the random pairing environment with costless market clearing volume is lower in the costly market and volume increases caused by an informational event persist after the event period this is consistent with existing empirical evidence and suggests that markets do not immediately clear all orders or that investors have demands to recontract

towards a sustainable electrification in ghana a review of renewable energy deployment policies abstract ghana has been facing perennial power rationing over the years due to fuel supply challenges the country s energy system is likely to suffer additional strain from rising energy demand fueled by population growth rapid urbanization and economic development fortunately there are enormous renewable energy resources which can provide sustainable electrification as backbone to socioeconomic development while curbing global warming ghana s energy strategy targets 100 access to electricity and 10 share of sustainable power in national generation mix by 2020 despite the existence of numerous policies and a renewable energy act current contribution of non conventional renewable energy to electricity generation is less than 1 the right mix of policies to address the unique domestic conditions and achieve its specific development goals remains insufficient this study reviews the regulatory framework financing incentives and other provisions of ghana s renewable energy act it critically examines the policy s strengths weaknesses opportunities and treats based on comparative analysis and lessons drawn from failed and successful implementation of similar policies around the world the study also assesses the impact of policy on project development it was found that the performance of ghana s renewable energy policy on grid connected electricity has been poor compared to its target the fundamental reasons for this unsatisfactory performance may be attributed to partial implementation of policies lack of market driven support schemes lack of pricing policy framework weak grid network limited access to funds and inconsistencies in renewable energy development strategies this study proposes the following countermeasures i ghana should comprehensively harmonize renewable energy regulatory and fiscal policies with domestic electricity pricing regime ii market driven support schemes should be prioritized for cost effectiveness and minimum governmental influence these reforms can help eliminate some of the major barriers to sustainable electrification in ghana while the lessons provide a learning curve for other african countries

the effect of derivative assets on information acquisition and price behavior in a rational expectations equilibrium this article shows that introducing derivative assets increases incentives to collect information about asset payoffs the increase in information collection makes the price of the underlying asset more informative and causes the expected price to increase extending the model to a dynamic setting with multiple risky assets we find the introducing derivative assets for one asset increases the expected prices of positively correlated assets and reduces price reaction to future earnings announcements these findings are consistent with the bulk of the empirical evidence on the relationship between the introduction of derivative assets and the behavior of asset prices article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

firms as portfolios a mean variance analysis of unquoted uk companies this paper adopts a mean variance portfolio framework to model the balance sheet behavior of unquoted companies with respect to choice items such as fixed investment investment in stocks trade credit and borrowing econometric results for a sample of thirty nine u k firms are consistent with many of the restrictions implied by portfolio theory in particular that these balance sheet items are jointly determined copyright 1989 by blackwell publishing ltd

the identification of preferences from equilibrium prices under uncertainty the competitive equilibrium correspondence which associates equilibrium prices of commodities and assets with allocations of endowments identifies the preferences and beliefs of individuals under uncertainty this is the case even if the asset market is incomplete

financial market innovation and security design an introduction abstract the article describes in the context of theory and practice this special issue of the journal of economic theory on financial market innovation and security design the main focus is on security design in incomplete financial markets possibly with asymmetrically informed traders we first survey the general equilibrium literature which emphasizes the spanning role of securities we then provide a unified framework encompassing the literature that employs a cara guassian setting to study the impact of financial innovation on risk sharing and information aggregation journal of economic literature classification numbers g10 d52

neoclassical consumer demand theory and the demand for money m friedman 1956 suggests that the demand for money should be analyzed in terms of consumer demand theory although often the interpretation of empirical results from studies using aggregate data appears to be in terms of the motives approach i e transactions precautionary and speculative motives the authors develop friedman s ideas within an explicit model of consumer theory and find that they provide a consistent framework for analyzing portfolio choice and offer greater insights into results from aggregate studies of the demand for money than the motives approach in particular the authors provide a new interpretation of the role of nominal interest rates inflation and a hicksian measure of wealth in the demand for money function copyright 1991 by royal economic society

information revelation and market incompleteness this paper introduces a theory of market incompleteness based on the information transmission role of prices and its adverse impact on the provision of insurance in financial markets we analyse a simple security design model in which the number and payoff of securities are endogenous agents have rational expectations and differ in information endowments and attitudes toward risk when markets are incomplete equilibrium prices are typically partially revealing while full relevation is attained with complete markets the optimality of complete or incomplete markets depends on whether the adverse selection effect the unwillingness of agents to trade risks when they are informationally disadvantaged is stronger or weaker than the hirshleifer effect the impossibility of trading risks that have already been resolved as new securities are issued and prices reveal more information when the hirshleifer effect dominates an incomplete set of securities is preferred by all agents and generates a higher volume of trade hirshleifer 1971 was the first to point out that revelation of information can reduce risksharing opportunities in insurance markets resulting in a welfare loss in this paper we build on hirshleifer s insight to develop a theory of endogenous market incompleteness we show that in an economy with asymmetric information in which agents learn from prices an incomplete financial structure may be optimal the reason is that less information is revealed by prices when markets are incomplete than in an otherwise identical economy with complete markets 1 paradoxically a greater degree of incompleteness may result in better risk sharing since the only risks that can be traded are those whose resolution is not common knowledge at the time of trade for the same reason incompleteness of markets may also foster a higher volume of trade the connection between security design asymmetric information trading volume and welfare in financial markets is a subtle one and it is important to isolate its various facets the efficacy of security markets in aggregating and transmitting private information depends on the characteristics of the financial structure and especially on the number of tradeable assets indeed within the rational expectations paradigm informational differences disappear in equilibrium generically when the price vector has

deliberating on renewable and sustainable energy policies in china abstract in order to realize the sustainable development of country and society many countries have established their renewable energy law and development strategy no matter developed countries or developing countries it is well known that china is the largest developing country in the world and the per capita gdp ranks more than 100 however the total gdp ranks the second due to the huge population amount and just behind usa certainly the total energy consumption amount is huge and the big energy demand has brought a serious of environmental problems such as acid rain water and soil pollution and resource exhaustion etc fortunately china central government has regarded the serious question to realize the sustainable development in future the renewable energy law has been established in 2005 firstly china s energy situation and existing environmental questions in past years is introduced in this paper secondly the distribution and the application practice of different renewable energy were introduced then china s renewable energy policy is detailed introduced in the following section the next section discusses the existing questions based on these discussions the development barriers and recommendations are introduced respectively

optimal innovation of futures contracts this article presents a simple model of the innovation of new futures contracts by transaction volume maximizing futures exchanges in incomplete markets under uncertainty with mean variance preferences and proportional transactions costs we characterize the set of nash equilibria for a number of exchanges simultaneously or sequentially choosing contracts the optimal monopolistic contract design is shown to be pareto optimal an example shows the failure of pareto optimality for aparticularnash equilibrium likewise in a monopolistic multiperiod setting an example shows the failure of pareto optimality given an incentive for the exchange to induce turnover

modelling money demand in open economies the case of selected asian countries while early work on money demand estimation focused primarily on the importance of domestic variables many studies in later years have suggested that foreign variables also influence the domestic demand for money in an open economy with the rapid financial market liberalization in some of the asian economies in the last couple of decades open economy factors have become very important in the determination of money demand therefore this paper aims to ascertain the degree to which foreign opportunity cost variables influence money demand in the philippines singapore and south korea cointegration analysis is performed and an error correction model estimated using quarterly time series data the empirical results support the inclusion of foreign opportunity cost variables in the money demand function

a review on global wind energy policy with the increasing negative effects of fossil fuel combustion on the environment in addition to limited stock of fossil fuel have forced many countries to inquire into and change to environmentally friendly alternatives that are renewable to sustain the increasing energy demand energy policy plays a vital role to mitigate the impacts of global warming and crisis of energy availability this paper explores the wind energy industry from the point of view of the wind energy policy it is noticed that energy policy could help increasing wind power generation as well as stimulating the energy industry it may be stated that without specific energy policy a country would not be able to solve the acute problems like reducing greenhouse gases ghgs emission scarcity of energy etc this paper discussed the existing successful energy policies for few selected countries based on literatures it has been found that fit rps incentives pricing law and quota system are the most useful energy policies practiced by many countries around the world then status of wind energy policy for malaysia was investigated and compared with few selected countries around the world

optimal security design how should new securities be designed traditional theories have little to say on this the literature on capital structure and general equilibrium theories with incomplete markets take the securities firms issue as exogenous this paper explicitly incorporates the transaction costs of issuing securities and develops a model where the instruments that are traded are chosen optimally and the economy s market structure is endogenous among other things it is shown that the firm s income stream should be split so that in every state all payoffs are allocated to the security held by the group that values them most this abstract was borrowed from another version of this item

portfolio behaviour in a flow of funds model for the household sector in india we estimate a flow of funds model for the household sector in india within the almost ideal demand system aids framework and examine the demand for money and the substitution effects between money and other financial assets the restricted long run model obtained using cointegration techniques provides stable equilibrium relationship between i 1 variables and broadly satisfies the axioms of rational choice in consumer demand theory we find that financial sector reform exerts a significant impact on the interest rate structure and household portfolio preferences specifically there is strong substitutability among risk free assets and a possible speculative effect in the stock market while the exchange rate strongly influences the demand for money these findings all have important policy implications

international good market segmentation and financial innovation abstract while international capital flows are now well liberalized markets for goods remain segmented to investigate how financial innovation may relieve the effects of this segmentation on risk sharing we examine a series of two country economies with internationally segmented good markets distinguished by the available financial securities sufficient conditions for efficiency include complete international financial markets together with liberalized international financial flows under these conditions heterogeneous agents from the same country may use securities as a substitute for the international shipment of goods this allows them to partially circumvent the segmentation allowing for efficient risk sharing

ambiguity aversion and incompleteness of financial markets it is widely thought that incomes risks can be shared by trading in financial assets but financial assets typically carry some risk idiosyncratic to them hence disposing incomes risk using financial assets will involve buying into the inherent idiosyncratic risk however standard theory argues that diversification would reduce the inconvenience of idiosyncratic risk to arbitrarily low levels this argument is less robust than what standard theory leads us to believe ambiguity aversion can exacerbate the tension between the two kinds of risks to the point that classes of agents may not want to trade some financial assets thus theoretically the effect of ambiguity aversion on financial markets is to make the risk sharing opportunities offered by financial markets less complete than it would be otherwise

optimal financial market integration and security design 1 we study 2 period pure exchange capital asset pricing model capm economies with incomplete financial markets and restricted participation we characterize the optimal financial market structure and efficient innovations consisting of both the introduction of new assets and the integration of segmented markets welfare gains from innovations are maximal when the endowments of affected agents are negatively correlated uncoordinated innovations lead to efficient market structures if all assets have identical participation structure or the markets being integrated trade identical assets however coordination failure in the introduction of new assets may result when assets have participation structures that overlap only partially

divergence of opinion in complete markets a note we consider an arrow debreu model with agents who have different subjective probabilities in general asset prices will depend only on aggregate consumption and the distribution of subjective probabilities in each state of nature if all agents have identical preferences then an asset with more dispersed subjective probabilities will have a lower price than an asset with less dispersed subjective probabilities if risk aversion does not decline too rapidly it seems that this condition is likely to be met in practice so that increased dispersion of beliefs will generally be associated with reduced asset prices in a given arrow debreu equilibrium there have been several recent investigations concerning the effect of heterogeneous probability beliefs on asset prices most of these investigations have taken place in the context of capm like mean variance models see for example lintner 5 miller 7 williams 10 jarrow 4 and mayshar 6 comparatively little has been done in the analysis of differences of opinion in an arrow debreu contingent claims context rubinstein 8 breeden and litzenberger 2 and breeden 1 have presented nice analyses of asset price determination in an arrow debreu model but most of their results have assumed commonly held probability beliefs in this paper we analyze the impact of divergence of opinion on asset prices in an arrow debreu economy the results serve to generalize the findings of rubinstein and breeden litzenberger to the case of different probability beliefs among the results we establish are 1 in equilibrium asset prices depend only on aggregate consumption and the distribution of subjective probability beliefs 2 asset values are an increasing function of any one individual s probability beliefs 3 an increase in the spread of the probability beliefs of investors may increase or decrease equilibrium asset values depending on the value of a parameter of the utility function however the most likely effect is to decrease the asset values these results are especially interesting in light of the recent empirical work of cragg and malkiel 3 they studied the relationship between ex post return and various measures of risk for common stocks and found that the measure of risk that performed best in their analysis was a measure of divergence of opinion

optimality of incomplete markets abstract in a static exchange economy where the traders initial endowments are risky the optimality of the financial structure is studied when markets are incomplete only financial structures with the same number of assets are compared a market structure is optimal when in a particular economy it yields an allocation of risks which cannot be pareto dominated through the implementation of any other market structure in a linear gaussian setup the optimal market structures are shown to span an eigenspace of a matrix which combines the risk exposures of the participants in the market approximately weighted by a measure of their risk aversions journal of economic literature classification numbers d60 g10

the financial structure and the demand for money in thailand this paper uses recently developed econometric techniques to investigate the demand for money in thailand initial estimates show the absence of any long term unique relationship among a monetary aggregate m1 or m2 an income and a price variable however the introduction of an exchange rate in the above relationship shows the presence of a cointegrating relationship this provides some support to mckinnon s hypothesis of currency substitution it also raises some concern about the closed economy focus of earlier studies on money demand in thailand addition of a foreign interest variable to the above models provide some support to the capital mobility hypothesis the long run elasticity estimates for the m1 equation raise some doubts about the desirability of using this monetary aggregate as an intermediate target by the bank of thailand the null hypothesis of a unit income elasticity and zero foreign interest elasticity are not rejected but the hypothesis of price homogeneity is rejected moreover

the significance of the market portfolio the market portfolio is in one sense the least important portfolio to provide to investors in an j agent one period stochastic endowment economy where preferences are quadratic a social welfare minded contract designer would never create a contract that would allow trading the market portfolio even the complete set of contracts all j 1 of them which achieve a first best solution never span the market portfolio these conclusions rely on the assumption that the contract designer has perfect information about agents utilities we also show that as the contract designer s information about agents utilities becomes more imperfect the optimal contracts approach contracts that weight individual endowments in proportion to elements of eigenvectors of the variance matrix of endowments then if there is a strong enough market component to endowments a portfolio approximating the market portfolio may be the most important portfolio

adverse selection and security design this paper studies the problem of optimal security design by a privately informed entrepreneur in the context of a simple parametric model it is shown that the entrepreneur does not find it profitable to float an asset that affords her an informational advantage the reason is that with rational uninformed outside investors the entrepreneur faces adverse selection in the security market which prevents her from exploiting her position as an insider this is true whether or not she has market power in trading the asset consider a risk averse entrepreneur who is contemplating what security to issue the entrepreneur anticipates that during subsequent trading in the secondary market she will have private information on the payoff of her investment as well as on other risks in the economy the design of the asset is therefore influenced not only by a desire to share risk but also by informational considerations involving the potential for insider trading profits this paper studies the problem of optimal security design in the context of a simple parametric model with gaussian risks and cara utility trading in the secondary market is modelled via the static reduced form concept of rational expectations equilibrium in which uninformed outside investors use market prices to try to infer the private information of the entrepreneur or insider as she will sometimes be called it is shown that the entrepreneur does not find it profitable to float an asset that affords her an informational advantage an optimal asset entails a fully revealing rational expectations equilibrium and is perfectly correlated with the issuer s endowment risk the reason is that with rational outside investors the entrepreneur faces adverse selection in the security market which prevents her from exploiting her position as an insider she is better off foregoing her informational advantage and concentrating on her hedging motive alone in the particular setting described in the paper equity2 is an optimal asset since the entrepreneur has no privileged information regarding its payoff and it allows efficient risk sharing the issue of security design when prices have an informational role to play is just beginning to be researched closely related to this paper is the work of demange and laroque 1995 who use a competitive rational expectations model with noise traders to analyse the problem posed above except for some special cases however they are able to get only numerical results in comparison the present paper obtains partially revealing equilibria in a model in which all agents are rational furthermore demange and laroque

inflation indexed bonds and nominal bonds financial innovation and precautionary motives this paper introduces a two period monetary general equilibrium model with proportional transaction costs on nominal and inflation indexed bonds this paper demonstrates that financial innovation on indexed bonds causes equilibrium interest rates of the nominal bond to increase when agents have precautionary saving motives this result implies that ignoring precautionary motives would underestimate savers welfare gain and overestimate borrowers welfare gain from innovation on indexed bonds

money demand in china in the reform period an error correction model based on integration and cointegration test findings this paper constructs an error correction ecm model to evaluate the dynamic adjustment process of money demand in china in the reform period 1979 to 1990 the cointegration tests suggest that some long run relationship exists among money demand real income price and the real interest rate the ecm model shows that the dynamic adjustment process of money demand maintains stable and significant relationships to most of its determinants

trading in derivatives when the underlying is scarce abstract regulatory restrictions and market frictions can constrain the aggregate quantity of long and short positions in a security when these constraints bind we refer to the security as scarce and its price becomes distorted relative to its value in a frictionless market we show that an otherwise redundant derivative can reduce the price distortion of the underlying security by relaxing its scarcity we also show that it is especially important to analyze the underlying and derivative markets jointly when evaluating the impact of regulation such as short sales bans and position limits in derivatives that restricts trade

private information and the design of securities the privileged information that the owners have on their firms may discourage rational financial investors and consequently may prevent the entrepreneurs from floating their company on the market the paper studies the validity of this argument in a model similar to that of grossman and stiglitz 8 an entrepreneur who contemplates issuing a new security faces a trade off between speculative gains which arise from his privileged information and an insurance motive associated with the insurance provided by the stock market we make explicit how this trade off depends on the fundamentals of the economy aggregate risk risk tolerance precision of the privileged information

welfare effects of financial innovation in incomplete markets economies with several consumption goods abstract we show that in almost every incomplete markets economy with more than one consumption good and with sufficiently many uninsured states of nature at any general equilibrium of this economy it is possible to arbitrarily perturb the equilibrium utilities merely by introducing the appropriate asset making for example all agents worse off this result demonstrates that the examples given by hart on the optimality of equilibrium when the market structure is incomplete j econ theory11 1975 418 443 and others are actually general phenomena and is in sharp contrast to the intuition that innovation since it expands financial opportunities should benefit all agents journal of economic literature classification numbers d52 d60 g10

financial liberalization in india and a new test of the complementarity hypothesis abstract this article reappraises the financial repression hypothesis for india in light of the partial liberalization of the financial sector in the early 1990s using for the first time state of the art multivariate cointegration and vector error correction models vecm from this more robust testing procedure we find that for the indian economy over the sample period 1951 99 money and capital are complementary suggesting that higher real interest rates will further raise the demand for money and lead to higher levels of investment furthermore testing for a structural break in the early 1990s to coincide with the liberalization of the financial sector in india suggests that these reforms have not significantly changed the complementary relationship between money and capital the policy implication is that further financial liberalization maybe required in india to enhance investment and economic growth

valuation adverse selection and market collapses we study a market for funding real investment where valuation meaning investors devoting resources to acquiring information about future payoffs creates an adverse selection problem unlike previous models more valuation is associated with lower market prices and so greater returns to valuation this strategic complementarity in the capacity to do valuation generates multiple equilibria with multiple equilibria the equilibrium without valuation is most efficient despite funding some unprofitable investments switches to valuation equilibria valuation runs look like credit crunches a large investor can ensure the efficient equilibrium only if it can precommit to a price and potentially only if subsidized

asset portfolios and credit rationing evidence from kenya this paper presents a model of the private sector s demand for financial and real assets in kenya for the period 1973 90 the private sector is assumed to hold its wealth in terms of five assets but is quantity rationed in the credit market the model is estimated as a co integrated demand system based on the almost ideal demand system of deaton and muellbauer 1980 the model highlights the role of real asset accumulation in offering a hedge against inflation and the role of credit rationing in the composition of wealth asset markets in developing countries and particularly those of sub saharan africa have typically been subject to controls on prices through interest rate controls and quantities through credit rationing it is natural to ask how these controls affect the level composition and evolution of private sector wealth for example how does the wealth portfolio respond to changes in the level of credit rationing how do controls on nominal interest rates determine the private sector s response to inflation since these questions are not readily addressed using conventional single equation models of money demand this paper examines them within a more general model of portfolio choice in which relative asset price effects and quantity rationing in the market for domestic credit are made explicit the econometric model which is similar to that of taylor and clements 1983 perraudin 1987 and barr and cuthbertson 1991 1992 1994 is based on a dynamic representation of the almost ideal demand system adapted to handle rationing using aggregate time series data for kenya the model characterizes the asset portfolio chosen by a representative private sec tor agent facing a two stage budgeting problem in the first stage the represen tative agent chooses his or her labour supply and consumption and hence the net addition to wealth at the second stage the new stock of wealth adjusted for capital and exchange rate gains or losses is allocated across different assets which in this case consist of money bank deposits and loans the latter being treated as negative assets real assets in the form of equity claims and govern ment securities the demand shares for the components of the portfolio are then estimated within an error correction system of equations the model is estimated on quarterly data for the period 1973 90 2 there are a number of reasons for adopting this particular approach first and most obviously the demand system provides for a more comprehensive description of the evolution of the overall portfolio composition than is poss ible using traditional single equation approaches this is particularly true in

speculation and risk sharing with new financial assets while the traditional view of nancial innovation emphasizes the risk sharing role of new nancial assets belief disagreements about these assets naturally lead to speculation which represents a powerful economic force in the opposite direction this paper investigates the eect of nancial innovation on portfolio risks in an economy when both the risk sharing and the speculation forces are present financial assets provide hedging services but they are also subject to speculation because traders do not necessarily agree about their payos i de ne the average variance of traders net worths as a measure of portfolio risks for this economy and i decompose it into two components the uninsurable variance de ned as the average variance that would obtain if there were no belief disagreements and the speculative variance de ned as the residual variance that results from speculative trades based on belief disagreements financial innovation always decreases the uninsurable variance because new assets increase the possibilities for risk sharing my main result shows that nancial innovation also always increases the speculative variance this is true even if traders completely agree about the payos of new assets the intuition behind this result is the hedge more bet more eect traders use new assets to hedge their bets on existing assets which in turn enables them to place larger bets and take on greater risks my second set of results concern endogenous nancial innovation when belief disagreements are su ciently large a pro t seeking market maker introduces assets that maximize the average variance among all possible choices completely disregarding the risk sharing motive for nancial innovation my third set of results concern a calibration of the model in the context of the gdp indexed assets proposed by athanasoulis and shiller 2001 when traders have reasonable amounts of belief disagreements these assets would have the unintended consequence of increasing their consumption risks

optimal spreading when spreading is optimal abstract this paper assumes an investor who has a non traded position operating in a stochastic interest rates environment the investor trades continuously either distinct futures contracts or distinct forward contracts in order to maximize his expected utility of terminal wealth in order to reach the welfare level of the first best optimum the investor must incorporate into his portfolio either two distinct futures contracts or two distinct forward contracts the optimal forward contracts dynamic spreading strategy has two components a speculative component and a minimum variance hedging component the minimum variance hedging component is composed of a short position in the nearby contract and a long position in the deferred contract the speculative component serves to replicate the growth optimum portfolio the speculative component is composed of a short position in the contract which is the most negatively correlated with the growth optimum portfolio and a long position in the other contract the marking to market procedure of the futures positions forces the investor to hold less futures contracts than the corresponding forward contract positions the analysis is also extended to incomplete markets and to inter market spreading

endogenous determination of the degree of market incompleteness in futures innovation abstract this paper studies the determination of the number of futures contracts created by an exchange we show that though the exchange can create the futures contracts costlessly if the investors have differential information there may be an upper bound on the number of contracts that the exchange is willing to create in a stylized economy we investigate what type of contracts and how many of these the exchange is willing to create journal of economic literature classification numbers d52 d82 g14

a note on parental and child risk valuation the paper develops a model that allows the estimation of parent s valuation of own and child health in an endogenous risk framework where parents can employ multiple activities to protect themselves and their children from a health risk these risk reducing activities may differ in their effectiveness and their intensity of use we suggest how to estimate the parent s ex ante marginal willingness to pay for a reduction in the ambient level of health risk unencumbered by expected utility terms

demand for money in sri lanka during the post 1977 period a cointegration and error correction analysis this paper investigates the long run demand for money and short run dynamics of the long run money demand function for sri lanka during the post 1977 period while m1 is cointegrated with real income nominal interest rate short term foreign interest rate and real effective exchange rate m2 is not this suggests that monetary authorities should emphasize the narrow definition of money for monetary control the one year fixed deposits rate is cointegrated with m1 indicating the opportunity cost of holding money although the inflation rate is not cointegrated with m1 it seems to be an important determinant of the demand for m1 in the short run results also suggest that the short term foreign interest rate and the exchange rate can have important implications for the effectiveness of monetary policy monetary authorities must consider the response of domestic money demand to these external factors when formulating future monetary policies

destructive interference in an imperfectly competitive multi security market abstract a general equilibrium framework is employed to illustrate how the advent of trading in new securities about which an insider has private information might cause a collapse of prevailing security markets roughly securities that allow the insider to hedge his portfolio risk interfere with one other and in some cases so much so that these securities cannot simultaneously trade in any equilibrium

on the flow of funds accounts and inter sectoral mobility of capital in india this study uses the flow of funds accounts framework and undertakes an in depth analysis of the inter sectoral mobility of capital in india unlike previous studies the fh model is estimated at th

financial innovation the bright and the dark sides based on data from 32 countries over the period 1996 2010 this paper is the first to assess the relationship between financial innovation on the one hand and bank growth and fragility as well as economic growth on the other hand we find that different measures of financial innovation capturing both a broad concept and specific innovations are associated with faster bank growth but also higher bank fragility and worse bank performance during the recent crisis these effects are stronger in countries with larger securities markets and more restrictive regulatory frameworks in spite of these seemingly ambiguous findings our evidence points to a positive net effect of financial innovation on economic growth financial innovation is associated with higher growth in countries and industries with better growth opportunities

a model of competitive stock trading volume a model of competitive stock trading is developed in which investors are heterogeneous in their information and private investment opportunities and rationally trade for both informational and noninformational motives i examine the link between the nature of heterogeneity among investors and the behavior of trading volume and its relation to price dynamics it is found that volume is positively correlated with absolute changes in prices and dividends i show that informational trading and noninformational trading lead to different dynamic relations between trading volume and stock returns

the taxation of trades in assets when the asset market is incomplete there typically exist taxes on trades in assets that are pareto improving this fiscal policy is anonymous it is fully and correctly anticipated by traders and it results in ex post pareto optimal allocations as such it improves over previously proposed constrained interventions

presidential address does finance benefit society academics view of the benefits of finance vastly exceeds societal perception this dissonance is at least partly explained by an underappreciation by academia of how without proper rules finance can easily degenerate into a rent seeking activity i outline what finance academics can do from a research point of view and from an educational point of view to promote good finance and minimize the bad

equilibrium open interest abstract this paper analyses what determines an individual investor s risk sharing demand for options and aggregating across investors what the equilibrium demand for options we find that agents trade options to achieve their desired skewness specifically we find that portfolio holdings boil down to a three fund separation theorem that includes a so called skewness portfolio that agents like to attain our analysis indicates also however that the common risk sharing setup used for option demand and pricing is incompatible with a stylized fact about open interest across strikes

a re examination of the demand for money in small developing economies this paper re examines the money demand function in three small open economies of asia korea pakistan and singapore in addition to using the relatively new procedure of error correction modelling the roles of variables such as a the expected change in the exchange rate b foregin interest rates and c foreign exchange risks on money demand are examined in testing the importance of these variables in the money demand function special attention is paid to testing the assumptions of the classical linear regression model the sample period for each country spans from 1973 1 through 1990 1 the empirical results suggest that the error correction specification performs very well in addition to the traditional variables the results suggest that at least some measure of foreign monetary developments appear to have some significant effect on money demand behaviour in these small developing economies

optimal futures innovation in a dynamic economy the discrete time case abstract we study the optimal futures innovation in a dynamic economy and investigate how the results obtained in a static economy should be modified due to the possibility of dynamic trading we analyze three different notions of ex ante optimality depending on the authority s ability to redistribute wealth among the investors and characterize the optimal futures innovation in each sense journal of economic literature classification numbers d52 d60 g10

diversification as a public good community effects in portfolio choice within a rational general equilibrium model in which agents care only about personal consumption we consider a setting in which due to borrowing constraints individuals endowed with local resources underparticipate in financial markets as a result investors compete for local resources through their portfolio choices even with complete financial markets and no aggregate risk agents may herd into risky portfolios this yields a pareto dominated outcome as agents introduce community risk unrelated to fundamentals moreover if some agents are behaviorally biased or cannot completely diversify their holdings rational agents may choose more extreme portfolios and amplify the effect

demand for money in bangladesh a cointegration analysis the aim of this study is to estimate the demand for real broad m2 money in bangladesh using the most recently developed autoregressive distributed lag approach to cointegration analyses the empirical results show that there is a unique cointegrated and stable long run relationship among real per capita broad money demand real per capita income domestic interest rates and unofficial exchange rate um premiums which act as a surrogate for foreign interest rates with money as the dependent variable the results show that the income and interest elasticities are positive while the um premium elasticity is negative these results suggest that distortions in the financial and foreign exchange markets should be reduced in order to increase financial saving or monetary accumulation our results also reveal that the demand for money in bangladesh is stable despite the changes in financial and exchange rate policies between 1975 and 1995

optimal incomplete markets with asymmetric information abstract this paper provides a simple parametric framework for comparing alternative incomplete asset structures in a productive economy focusing on the role of assets in allocating risk and transmitting private information it characterizes asset structures that are constrained efficient in the sense that no other asset structure with the same number of securities leads to a pareto dominating allocation in equilibrium specifically a constrained efficient asset structure must be efficient with respect to both risk sharing and information transmission explicit optimality criteria are developed and used to evaluate innovation by volume maximising futures exchanges journal of economic literature classification numbers g14 d52 d82

the analysis on photovoltaic electricity generation status potential and policies of the leading countries in solar energy abstract energy which is the main agenda of our world is crucially important for the people many countries frequently held meetings and discussions with energy agenda these countries are working to balance the energy demand and supply for finding the solution are researched researches should be attempted to present a more efficient way to use energy as well as renewable energy resources effectively photovoltaic energy power systems take place as the most dominant source among renewable energy technologies the most important reason is that it is unlimited and clean energy of the solar power systems many studies show that photovoltaic power systems will have an important share in the electricity of the future in this study to generate electricity from solar energy using photovoltaic systems have a leading position in some european countries united states of america china and japan s current status and future policies will be analyzed in various comments were made

arbitrage short sales and financial innovation the authors describe a model of general equilibrium with incomplete markets in which firms can innovate by issuing arbitrary costly securities when short sales are prohibited firms behave competitively and equilibrium is efficient when short sales are allowed these classical properties may fail if unlimited short sales are allowed imperfect competition may persist even when the number of potential innovators is large if limited short sales are allowed perfect competition may obtain in the limit but equilibrium can be inefficient because of the presence of an externality the private benefits of innovation for firms differ from the social benefits copyright 1991 by the econometric society

credit risk transfer and contagion some have argued that recent increases in credit risk transfer are desirable because they improve the diversification of risk others have suggested that they may be undesirable if they increase the risk of financial crises using a model with banking and insurance sectors we show that credit risk transfer can be beneficial when banks face uniform demand for liquidity however when they face idiosyncratic liquidity risk and hedge this risk in an interbank market credit risk transfer can be detrimental to welfare it can lead to contagion between the two sectors and increase the risk of crises

exchange rate sensitivity of demand for money and effectiveness of fiscal and monetary policies one of the arguments between proponents and opponents of floating exchange rates centres around the relative effectiveness of fiscal and monetary policy while proponents of floating rates argue that monetary policy is more effective under floating rates its opponents contend that fiscal policy is more effective under fixed rates however economic theory suggests that there is room for both policies under both types of exchange rate system depending upon degree of sterlization concentrating on the floating rates mundell 1963 has argued that the relative effectiveness of monetary and fiscal policies would also depend upon sensitivity of money demand to exchange rate more precisely he has conjectured that the demand for money is likely to depend upon the exchange rate in addition to the interest rate and the level of income this would slightly reduce the effectiveness of a given change in the quantity of money and slightly increase the effectiveness of fiscal policy on income and employment under

competition in financial innovation this paper examines the incentives to innovate securities provided by frictionless competitive markets with short sales to entrepreneurs in economies with symmetric investor utilities we provide the conditions under which a rm s market value is maximized by a complete nancial structure that is when the mechanism that gives rise to market incompleteness is the one illustrated in the classical example of allen and gale 1991 the foundation for incompleteness in that case is derived from innovation costs and free riding among entrepreneurs for the class of preferences where an incomplete nancial structure maximizes the rms market values markets are incomplete with a probability of one even when innovation is cost free in this sense we provide an alternative to allen and gale s foundation for market incompleteness

a dynamic equilibrium model of asset prices and transaction volume a dynamic general equilibrium model of capital asset pricing is constructed in which the volume of capital traded is determined endogenously the model also gives rise to a novel asset pricing formula it is shown that temporary shocks can give rise to serially correlated changes in the price of capital and transaction volume that persist long after the initial disturbance the frequency and amplitude of the resulting cycles are related to the length of the agent s planning horizon and the discount factor the model s implications for explaining asset price volatility are also explored

fostering a renewable energy technology industry an international comparison of wind industry policy support mechanisms this article examines the importance of national and sub national policies in supporting the development of successful global wind turbine manufacturing companies we explore the motivations behind establishing a local wind power industry and the paths that different countries have taken to develop indigenous large wind turbine manufacturing industries within their borders this is done through a cross country comparison of the policy support mechanisms that have been employed to directly and indirectly promote wind technology manufacturing in 12 countries we find that in many instances there is a clear relationship between a manufacturer s success in its home country market and its eventual success in the global wind power market whether new wind turbine manufacturing entrants are able to succeed will likely depend in part on the utilization of their turbines in their own domestic market which in turn will be influenced by the annual size and stability of that market consequently policies that support a sizable stable market for wind power in conjunction with policies that specifically provide incentives for wind power technology to be manufactured locally are most likely to result in the establishment of an internationally competitive wind industry

are more risk averse agents more optimistic insights from a rational expectations model we analyze the link between pessimism and risk aversion we consider a model of partially revealing competitive rational expectations equilibrium with diverse information in which the distribution of risk aversion across individuals is unknown we show that when a high individual level of risk aversion is taken as a signal for a high average level of risk aversion more risk averse agents are more optimistic this correlation between individual risk aversion and optimism leads to a pessimistic consensus belief hence to an increase in the market price of risk risk sharing schemes and welfare implications are analyzed we show that agents welfare may increase upon the receipt of more precise information

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

asset pricing in a production economy with incomplete information this paper analyzes an economy in which investors operate under partial information about technology relevant state variables it is shown that for gaussian information structures under incomplete observations the consumer s problem can be transformed into an equivalent program with a completely observed state the conditional expectation of the underlying unobservable state variables a consequence of this transformation is that classic results in finance remain valid under an appropriate reinterpretation of the state variables the static capital asset pricing model capm of sharpe 24 lintner 16 and mossin 20 states that the expected premium on any risky asset is proportional to the premium on the market as a whole this theoretical linear relationship however is subject to criticisms on two grounds first it does not seem to be supported by the empirical evidence second it is based on the premises of a constant opportunity set merton 19 subsequently relaxes this assumption and shows that when the opportunity set fluctuates over time due to changes in the state of the economy individual securities are also priced with respect to selected portfolios funds providing a hedge against unanticipated fluctuations 2 more recently breeden 3 has extended merton s results by emphasizing the role of aggregate consumption in pricing relationships in this paper we seek to further our understanding of asset pricing by relaxing the assumption that investors observe the state of the economy in the mertonbreeden framework observed state variables affect the means and variances of asset returns implying deformations of the opportunity set over time from a practical point of view it seems that this complete information assumption is violated investors in financial markets operate under partial knowledge of the microvariables which influence production and the returns on assets their decisions rely mostly on information through noisy channels such as newspapers technical reviews or weather reports in this paper we attempt to model such
