expectations the exchange rate and the current account abstract a critical examination is undertaken of the relationship between the exchange rate and the current account in a small open economy theoretically the correlation between the exchange rate and the current account seems to be ambiguous in particular the association between movements in the exchange rate and the current account is likely to depend in an essential manner on the nature of exogenous disturbances affecting the two variables simultaneously lastly the question of the role of an optimal monetary policy and the choice of an exchange rate regime in an uncertain environment is raised

time preference and international lending and borrowing in an overlapping generations model two economies represented by diamond type overlapping generations models and differing only in their pure rates of time preference are joined together capital formation balance of payments behavior and welfare are compared under autarky and openness with a positive natural rate of growth the low time preference country runs a current account surplus in the steady state but not necessarily outside it if preexisting capital is not shiftable between countries integration in the world economy makes the high time preference country worse off in the short run the ranking of stationary utility levels under autarky and openness is ambiguous

on the determination of the external debt the case of israel abstract this paper pursues the econometric implementation of an intertemporal optimization model of the foreign debt with israeli data in this model the private sector faces perfect capital markets and maximizes utility from consumption over an infinite horizon the intertemporal budget constraint recognizes the intertemporal finance equation of the government under these conditions the effect of current disturbances in output government spending and unilateral transfers on private consumption and foreign borrowing is determined by their perceived future persistence the model passes a formal econometric test however some results are also suggestive of omitted considerations

anticipated foreign military threat arms accumulation and the current account in a small open economy this paper examines the effects of an anticipated foreign military threat on consumption the home weapons stock and net foreign asset position in a small open economy if the utility function is separable between butter and guns the economy decreases both butter and guns when the news arrives accumulates foreign assets prior to the foreign threat realization and increases guns as the foreign threat realizes if the utility function is nonseparable between butter and guns the economy may have two dynamic responses the first is similar to the separable case except that consumption exhibits a discrete jump when the foreign threat realizes the second is that the economy increases both butter and guns on impact decumulates foreign assets prior to the foreign threat implementation but either increases or decreases guns as the foreign threat realizes

deficits and intergenerational welfare in open economies this paper deals with public debt in open economies extending diamond s overlapping generations model to a small open economy as well as an international equilibrium of two large economies it focuses on the intergenerational welfare redistributions caused by an increase in public debt triggered by a temporary government budget deficit and shows how these redistributions differ in open and closed economies the interplay between the deficits in the government budget and the current account is also analyzed it is shown how a single period with a government deficit can be followed by a sequence of periods with a deficit in the current account

replacement of agricultural price supports by area payments in the european union and the effects on pesticide use this article determines the contribution of recent european union agricultural policy reforms on the use of pesticides our theoretical model extends the multioutput generalization of the lichtenberg zilberman damage control technology model developed by chambers and lichtenberg our empirical analysis uses farm level data for a sample of french farms results suggest that price effects on the use of pesticides are always more elastic than area payment effects this indicates that policy reforms consisting of a reduction in price supports in favor of area payments may reduce application of crop protection inputs such policy changes which represent a certain degree of decoupling took place under the 1992 common agricultural policy reforms

normal inputs and joint production with allocatable fixed factors when jointness is caused by allocatable fixed factors in the normal case the marginal cost of any output increases as any other output increases the supply of any output decreases as any other output price increases and an input price increase may cause the supply of some outputs to increase

the current account in the macroeconomic adjustment process macroeconomic adjustments to changes in the economic environment are to a large extent conditioned by the intertemporal choices of economic agents when agents face an intertemporal budget constraint a decision to alter current indebtedness implies changes in future consumption possibilities and will be based on expectations of the entire future path of key variables and not only current variables a formal model to show how today s current account is a function of both current and future economic variables is presented the determination of the current account under classical assumptions of market clearing and continuous full employment is emphasized

spatial heterogeneity contract design and the efficiency of carbon sequestration policies for agriculture abstract in this paper we develop methods to investigate the efficiency of alternative contracts for carbon c sequestration in cropland soils taking into account the spatial heterogeneity of agricultural production systems and the costs of implementing more efficient contracts we describe contracts being proposed for implementation in the united states and other countries that would pay farmers for adoption of specified practices per hectare contracts we also describe more efficient contracts that would pay farmers per tonne of soil c sequestered and we show how to estimate the costs of implementing these more efficient contracts in a case study of a major agricultural region in the united states we confirm that the relative inefficiency of per hectare contracts varies spatially and increases with the degree of spatial heterogeneity the results also show that per hectare contracts are as much as five times more costly than per tonne contracts a degree of inefficiency similar to that found in assessments of command and control industrial emissions regulations measurement costs to implement the per tonne contracts are found to be positively related to spatial heterogeneity but are estimated to be at least an order of magnitude smaller than the efficiency losses of the per hectare contract for reasonable error levels this finding implies that contracting parties could afford to bear a significant cost to implement per tonne contracts and achieve a lower total cost than would be possible with the less efficient per hectare contracts

international debt and world business fluctuations abstract the international transmission of real productivity disturbances is examined in an optimizing model with two countries each inhabited by an infinitely lived representative consumer producer we analyze the dynamics of output consumption investment interest rates and net external debt foreign productivity shocks can have positive or negative impacts on domestic output and international debt depending on the intertemporal distribution of the shocks transient foreign shocks are shown to be positively transmitted and lead to increased domestic indebtedness while permanent foreign shocks are negatively transmitted and lead to a decline in domestic indebtedness

welfare effects of alternative forms of public spending the paper analyzes welfare effects in a second best world of public spending of three different types transfer payments public consumption and public investment it is shown how these effects d

profit maximizing land use revisited the testable implications of non joint crop production under land constraint this article derives new implications for the land allocation and production decisions of profit maximizing farm firms where production of different crops is non joint but subject to a constraint on the total land area these implications are observable and thus subject to empirical scrutiny an estimable model of crop production land allocation and input use decisions is derived that permits joint production and enables the implications of non joint but land constrained production to be tested this may improve econometric estimates of cross price elasticities of supply by linking models of land use and production decisions and allowing non jointness to be imposed where appropriate copyright 2013 oxford university press

government spending and the optimal rates of consumption and capital accumulation this paper investigates the effects of a temporary change in government expendit ure on private consumption and investment the model employed is one of a closed economy populated by infinitely lived utility maximizing individuals the analysis focuses on the implications of alternative assumptions concerning the relationship between public and private c onsumption in the household s utility function a temporary increase in government expenditure is found to reduce investment if public and private goods are edgeworth complements or independent however if they are substitutes there exists the possibility of an increase in investment

output effects of government purchases the theoretical analysis focuses on the distinction between temporary and permanent movements in government purchases under plausible conditions the temporary case involves an output response that is positive less than one to one with the change in government purchases and larger than that generated by an equal sized but permanent shift in purchase the equilibrium real rate of return rise in the temporary case but changes little in the permanent one defense purchases are divided empirically into permanent and temporary components by considering the role of temporary wars no temporary shifts in nondefense purchases were isolated empirical results verify an expansionary output effect for temporary purchases that exceeds that of permanent purchases the results for some other expectational hypotheses are found to be generally supportive of the theory

aggregate spending and the terms of trade is there a laursen metzler effect this paper investigates the spending and current account effects of terms of trade shifts in a model where households maximize utility over an infinite planning period in the framework developed here an economy specialized in production must experience a fall in aggregate spending and a current surplus as a result of an unanticipated permanent worsening in its terms of trade the paper s model thus provides a setting in which the current account deficit predicted by laursen and metzier harberger and others fails to materialize

modeling supply response in a multiproduct framework the paper models multiproduct supply response in agriculture and tests key assumptions traditionally maintained in supply response studies the technology is approximated by a restricted profit function the properties of the restricted profit function are imposed during estimation the hypothesis that maintains the existence of output price and quantity indexes that satisfy the adding up property is rejected the existence of individual production functions for each output is also rejected unless joint production is permitted the estimates of responsiveness of a particular commodity to changes in own price or prices of competing outputs are likely to be considerably understated

structural agricultural land use modeling for spatial agro environmental policy analysis this paper develops a spatially disaggregated structural econometric model of agricultural land use and production based on the joint multi output technology representation introduced by chambers and just 1989 starting from a flexible specification of the farm profit function we derive land use allocation input application crop yield and livestock intensity equations in a joint and theoretically consistent framework to account for the presence of censored observations in micro level data the model is estimated as a system of two limit tobit equations via quasi maximum likelihood we present an empirical application using fine scale spatial data covering the entirety of england and wales and including the main economic policy and environmental drivers of land use change in the past forty years a simulation of the effects of diffuse pollution reduction measures illustrates how our approach can be applied for agro environmental policy appraisal

the real exchange rate the capital stock and fiscal policy abstract this paper studies the joint determination of aggregate supply the real exchange rate and the current account in response to changes in government spending in a model where there is no uncertainty in the aggregate but where individuals are uncertain about their lives duration international capital mobility fixes the steady state capital stock and aggregate supply in a small country whereas in a large country the steady state capital stock is endogenous an increase in government spending is more likely to generate a real exchange rate depreciation in a small country since the loss of wealth associated with cumulated current account deficits does not increase rest of the world spending in the case of a large country current account deficits are wealth transfers to the rest of the world and increase foreign spending thus the normal long run response is an increase in the relative price of domestic output

the terms of trade and the current account the harberger laursen metzler effect the paper examines the effect of terms of trade changes on a small country s spending and current account assuming optimizing behavior in an intertemporal framework with perfect international capital mobility a temporary future terms of trade deterioration implies a deterioration improvement of the trade balance whereas a permanent terms of trade deterioration has an ambiguous effect depending on the rate of time preference nominal and real variables are considered via exact price indexes two periods and an infinite horizon are examined

allocatable fixed inputs and jointness in agricultural production implications for economic modeling allocatable fixed inputs such as land are a potentially important source of jointness in agriculture as with other causes of jointness they necessitate multiple product systems for modeling product supply and input demand in other important ways however their analytical implications are very different from other causes of jointness model specification differs demand functions for the quantities of each input used in the production of individual commodities can be derived if a primal approach is used but such allocation equations cannot in general be identified from a dual specification available allocation data are not even useful in such dual estimations

the international transmission and effects of fiscal policies in recent years the world economy has been subject to large and unsyncronized changes in fiscal policies high and volatile real rates of tnterest large fluctuations in real exchange rates and significant variations in private sector spending this paper reviews some of the key facts characterizing the effects of fiscal policies during the first half of the 1980s and provides a simple analytical framework suitable for the interpretation of these facts the analytical framework builds on a two country model of the world economy which is applied to the analysis of the transmission and effects of various changes in the time profile of taxes and of government spending generally the predictions of the model concerning the relation among the intercountry patterns of consumption long and short term real rates of interest real exchange rates and fiscal policies are consistent with the stylized facts this abstract was borrowed from another version of this item

temporary stabilization predetermined exchange rates the paper analyzes the impact of a stabilization policy based on a temporary reduction in the rate of devaluation against a background in which a constant rate of devaluation has no real effects it is shown that the temporary policy does and furthermore that the real effects tend to become bigger in absolute value as the horizon of the temporary policy is shortened the central discussion is carried out in terms of a one good cash in advance model with perfect capital mobility and ramsey type consumers results are extended to account for home goods and variable velocity the roles of capital mobility and banking liberalization are briefly discussed

equilibrium pricing and trading volume under preference uncertainty information collection processing and dissemination financial institutions is challenging this can delay the observation by traders of the exact capital charges and constraints of their institution during this delay traders face preference uncertainty in this context we study optimal trading strategies and equilibrium prices in a continuous centralized market we focus on liquidity shocks during which preference uncertainty is likely to matter most preference uncertainty generates allocative ineficiency but need not reduce prices traders progressively learning about the preferences of their institution conduct round trip trades which generate excess volume relative to the frictionless market in a cross section of liquidity shocks the initial price drop is positively correlated with total trading volume across traders the number of round trips is negatively correlated with trading profits and average inventory

devaluation levels versus rates abstract in a context of infinitely lived families a la sidrauski where consumers are lump sum compensated for the inflation tax and there is no capital mobility it is shown that a devaluation improves while an increase in the rate of devaluation deteriorates the balance of payments

optimal taxation and debt in an open economy abstract we characterize the time profile of the optimal consumption tax in a small open economy under foreseen fluctuations in the taste for current consumption productivity or external interest rates we give conditions for the efficient tax to be lowered or raised when productivity rises taste fluctuations are parameterized to be equivalent to effective consumption price fluctuations we give conditions under which the optimal tax rises or falls with the effective price in contrast the optimal tax rate is invariant to changes in the interest rate the associated behavior of optimal debt is also characterized

effects of government spending on the current account with endogenous time preference this paper extends a previous model to set up a small open economy with perfect capital mobility and examines the effects of an unanticipated permanent rise in public spending on the optimal rates of private consumption and the current account the novelty of the paper is consideration of the relationship between private and public consumption in the household s utility function as well as endogenous rates of time preference it is found that the key factor determining the adjustment patterns of private consumption and the current account is the marginal utility of private consumption and of public spending which results from endogenous recursive preferences

liquidity based competition for order flow we present a microstructure model of competition for order flow between exchanges based on liquidity provision we find that neither a pure limit order market plm nor a hybrid specialist limit order market hm structure is competition proof a plm can always be supported in equilibrium as the dominant market i e where the hybrid limit book is empty but an hm can also be supported for some market parameterizations as the dominant market we also show the possible coexistence of competing markets order preferencing that is decisions about where orders are routed when investors are indifferent is a key determinant of market viability welfare comparisons show that competition between exchanges can increase as well as reduce the cost of liquidity active competition between exchanges for order flow in cross listed securities is intense in the current financial marketplace examples include rivalries between the new york stock exchange nyse crossing networks and ecns and between the london stock exchange the paris bourse and other continental markets for equity trading and between eurex and london international financial futures and options exchange liffe for futures volume while exchanges compete along many dimensions e g payment for order flow transparency execution speed liquidity and price improvement will in our view be the key variables driving competition in the future over time high cost markets should be driven out of business as investors switch to cheaper trading venues moreover market structure is increasingly singled out by regulators exchanges and other market participants as a major determinant of liquidity 1

opaque trading disclosure and asset prices implications for hedge fund regulation we construct a rational expectations equilibrium model to investigate the effect of ambiguity about hedge fund strategies on market efficiency and aggregate welfare in our model some traders mutual funds view the equilibrium trading strategies of other traders hedge funds as ambiguous this ambiguity limits the ability of mutual funds to infer information from prices and affects the market performance we use this analysis to investigate the implications of regulations that affect the amount of ambiguity about hedge fund strategies or the cost of operating a hedge fund our analysis demonstrates how regulations affect asset prices and welfare through their influence on opaque trading

has new york become less competitive than london in global markets evaluating foreign listing choices over time abstract we study the determinants and consequences of cross listings on the new york and london stock exchanges from 1990 to 2005 this investigation enables us to evaluate the relative benefits of new york and london exchange listings and to assess whether these relative benefits have changed over time perhaps as a result of the passage of the sarbanes oxley act in 2002 we find that cross listings have been falling on us exchanges as well as on the main market in london this decline in cross listings is explained by changes in firm characteristics instead of by changes in the benefits of cross listing we show that after controlling for firm characteristics there is no deficit in cross listing counts on us exchanges related to sox investigating the valuation differential between listed and non listed firms the cross listing premium from 1990 to 2005 we find that there is a significant premium for us exchange listings every year that the premium has not fallen significantly in recent years and that it persists when allowing for time invariant unobservable firm characteristics in contrast no premium exists for listings on london s main market in any year firms increase their capital raising activities at home and abroad following a cross listing on a major us exchange but not following a cross listing in london our evidence is consistent with the theory that an exchange listing in new york has unique governance benefits for foreign firms

the effect of market segmentation and illiquidity on asset prices evidence from exchange listings this article documents the effect on share value of listing on the new york stock exchange and reports the results of a joint test of merton s 1987 investor recognition factor and amihud and mendelson s 1986 liquidity factor as explanations of the change in share value we find that during the 1980s stocks earned abnormal returns of 5 percent in response to the listing announcement and that listing is associated with an increase in the number of shareholders and a reduction in bid ask spreads cross sectional regressions provide support for both investor recognition and liquidity as sources of value from exchange listing the effect on share value of listing on the new york stock exchange nyse by over the counter otc stocks has been the focus of empirical investigation by scholars and practitioners for at least 50 years the consensus conclusion is that an nyse listing is or at least has been associated with a significant increase in share price streetlore has historically attributed this increase in value to the increased investor recognition that is believed to accompany listing on a major exchange until recently this investor recognition explanation has lacked a rigorous analytical foundation merton 1987 fills this void with a model of capital market equilibrium with incomplete information to develop his model merton adopts most of the assumptions of the original sharpe lintner mossin capital asset pricing model capm but relaxes the assumption of equal information across investors he further assumes that investors invest only in the those securities of which they are aware 2 with this modification to the original capm framework merton derives a model in which expected returns increase with systematic risk firm specific risk and relative market value and decrease

optimal taxes and the structure of preferences if optimal tax theory is to be the basis for calculating tax rates a close understanding is required of the relationship between the structure of preferences and the configuration of optimal tax rates otherwise hypotheses chosen by the econometrician for practical convenience may completely determine the results independently of measurement this paper explores the relationship between various types of separability particularly weak and implicit separability and optimal tax rates in the various models discussed in the literature the use of distance functions and the antonelli matrix provides a significant unification of previously disparate results in the final analysis optimal tax theory should be the basis for actual calculation of tax rates although recently there have been great advances in theoretical results and in our understanding of their meaning we are still some way from a working knowledge of whether uniform commodity taxes are in practice optimal or if not which commodities should be discriminated against present theoretical formulae do not yield clear cut results except in special cases and it has recently become clear that optimal rates depend crucially on the detailed structure of consumer preferences for example atkinson and stiglitz 3 show that with an optimal nonlinear income tax discriminatory commodity taxes are only necessary to the extent that individual commodities are not weakly separable from leisure more recently deaton 6 has shown that a similar result holds for what is perhaps the most interesting of the standard models that where there are many consumers and only a linear income tax and proportional commodity taxes are allowed in this case separability between goods and leisure together with linear engel curves for goods removes the need for differential commodity taxation in consequence nothing can be learned about commodity taxes from consumer demand studies in which commodity demands are explained conditionally on total expenditure and commodity prices and which assume linear engel curves all such studies require separability from leisure as a maintained hypothesis and so are consistent with uniform commodity taxation these results suggest that the prospects for meaningful empirical calculations of tax rates are bleak econometricians estimating commodity demand and labor supply equations make generous use of separability assumptions to enable estimation at all in consequence it is likely that empirically calculated tax rates based on econometric estimates of parameters will be determined in structure not by the measurements actually made but by arbitrary untested and even unconscious hypotheses chosen by the econometrician for practical convenience to remedy this situation and as a prelude to fruitful empirical work it is necessary to have a more explicit understanding of how preference structure affects optimal tax rates such is the object of this paper three different

capital movements intersectoral resource shifts and the trade balance abstract in this paper i consider the interactions between the internal structure of the economy and its external balance in an intertemporal set up with perfect foresight a simple pattern emerges current account deficits are associated with depreciating real exchange rates the incorporation of real investments and government spendings change this pattern in a systematic way depending on factor intensities the composition of government spending and its timing

capital controls and fiscal policy in the world economy an intertemporal utility maximization framework is employed to model a world economy with capital controls the effects of fiscal policy in such an environment are examined several results emerge concerning the international transmission of fiscal policy under capital controls and the nature of comovements in macro economic aggregates such as output employment consumption and investment some of the paper s other results concern the implications of capital controls for ricardian equivalence the role of financing decisions in the international transmission process under capital controls and the effect of capital controls on the magnitude of fiscal induced fluctuations throughout the world economy contr6les des mouvements de capitaux et politique fiscale dans l conomie mondiale les auteurs utilisent une approche par la maximisation intertemporelle de l utilite pour modeliser une economie mondiale dans laquelle des controles sur les mouvements de capitaux existent ils examinent les effets de la politique fiscale dans un tel contexte on tire de ces analyses plusieurs resultats quant i la transmission internationale des effets de la politique fiscale et quant aux mouvements lies de certains agregats economiques comme les niveaux de production d emploi de consommation et d investissement certains autres resultats de cette analyse ont trait aux implications des controles des mouvements de capitaux sur l1 quivalence ricardienne au role des decisions de financement dans le processus international de transmission quand il y a controle des mouvements de capitaux et aux effets des controles sur les mouvements de capitaux sur la magnitude des fluctuations induites a travers l economie mondiale par la politique fiscale helpful comments from two anonymous referees are gratefully acknowledged discussion in workshops held at ucla duke university iowa state university queen s university vanderbilt university vpi and the university of western ontario has also been useful canadian journal of economics revue canadienine d economique xviii no 4 november novembre 1985 printed in canada imprime au canada 0008 4085 85 743 65 1 50 canadian economics association this content downloaded from 207 46 13 129 on mon 27 jun 2016 05 25 03 utc all use subject to http about jstor org terms 744 jeremy greenwood and kent p kimbrough

a model of trade in exhaustible resources what distinguishes exhaustible resources from most other goods is not only their non renewable nature but also a combination of two other important characteristics related to their economic functions in their role as an input resources serve as an esseptial factor in the production of final goods moreover because their usefulness remains intact until they are consumed in the process of production they may also serve as a store of value in the absence of other types of marketable assets this latter characteristic enables the owner of the resource to achieve through optimal resource management his desired time profile of consumption corresponding to these two economic functions are two possible motives for international trade in exhaustible resources first in connection with their role as a productive input trade in resources promotes efficiency in the allocation of factors of production throughout the world economy on the basis of this motive for trade countries with a relatively high per capita endowment of the resource should be expected to export the resource in exchange for final goods second in connection with their asset function trade in resources may be viewed as a means of achieving efficiency in the intertemporal allocation of consumption goods among countries economies with a relatively high rate of time preference desire a relatively high ratio of current to future consumption accordingly impatient countries might be expected to import consumption goods in exchange for the resource in the present and export consumption goods in the future the interaction between these two motives for trade is examined in the present paper within a simple two period two country model traded objects are assumed to be an exhaustible resource and a single consumption good although the possibility of trade in consumption loans is also considered later in the paper the consumption good is produced in both countries with the aid of labor and the resource because the latter has the dual role of being a productive input as well as a store of value in the model international trade is viewed both as a means of reallocating the world s endowment of the resource so as to ensure

the current account and the optimal government debt abstract in this paper we analyze the optimal response of the current account and the government debt to real disturbances permanent and temporary lumpsum taxes are not feasible and the government income is raised according to the ramsey rule for optimum taxation we show that permanent disturbances have no effects on either the private or the government current account if initially there are no deficits starting off from the same initial situation both the private sector and the government develop a deficit on current account in response to a temporary disturbance

the effects of market segmentation and investor recognition on asset prices evidence from foreign stocks listing in the united states non u s firms cross listing shares on u s exchanges as american depositary receipts earn cumulative abnormal returns of 19 percent during the year before listing and an additional 1 20 percent during the listing week but incur a loss of 14 percent during the year following listing we show how these unusual share price changes are robust to changing market risk exposures and are related to an expansion of the shareholder base and to the amount of capital raised at the time of listing our tests provide support for the market segmentation hypothesis and merton s 1987 investor recognition hypothesis the globalization of u s capital markets has accelerated dramatically in the past decade increasing numbers of companies from overseas have chosen to either raise capital through global equity issues or prepare for future capital raising by way of cross listings on u s exchanges as of 1997 about 1 300 non u s companies have listed their shares for trading on the new york stock exchange nyse the american exchange amex the national association of securities dealers automation quotation nasdaq system or

liquidity and valuation in an uncertain world abstract during the 2007 2009 financial crisis there was little or no trading in a variety of financial assets even though bid and ask prices existed for many of these assets we develop a model in which this illiquidity arises from uncertainty and we argue that this new form of illiquidity makes bid and ask prices unsuitable as metrics for establishing fair value for these assets we show how the extreme uncertainty that traders face can be characterized by incomplete preferences over portfolios and we use bewley s 2002 model of decision making under uncertainty to derive equilibrium quotes and the nonexistence of trading at these quotes we then suggest alternatives for valuing assets in illiquid markets

an empirical analysis of stock and bond market liquidity this article explores cross market liquidity dynamics by estimating a vector autoregressive model for liquidity bid ask spread and depth returns volatility and order flow in the stock and treasury bond markets innovations to stock and bond market liquidity and volatility are significantly correlated implying that common factors drive liquidity and volatility in these markets volatility shocks are informative in predicting shifts in liquidity during crisis periods monetary expansions are associated with increased liquidity moreover money flows to government bond funds forecast bond market liquidity the results establish a link between macro liquidity or money flows and micro or transactions liquidity a number of important theorems in finance rely on the ability of investors to trade any amount of a security without affecting the price however there exist several frictions 1 such as trading costs short sale restrictions and circuit breakers that impact price formation the influence of market imperfections on security pricing has long been recognized liquidity in particular has attracted a lot of attention from traders regulators

real interest rates home goods and optimal external borrowing the paper investigates the optimal time path of consumption and external borrowing in the dependent economy model the small country faces given world prices and a given world real interest rate the presence of a home goods sector implies that the relevant real interest rate appropriate to consumption decisions depends on the rate of change of the real price of home goods the paper shows how transitory disturbances in output or in the world real interest rate affect the time profile of consumption and the trade balance in particular it is shown that the presence of a home goods sector dampens the consumption effects of changes in the world interest rate

volatility of aggregate volatility and hedge fund returns abstract this paper investigates empirically whether uncertainty about equity market volatility can explain hedge fund performance both in the cross section and over time we measure uncertainty via volatility of aggregate volatility vov and construct an investable version through returns on lookback straddles on the chicago board options exchange cboe volatility index vix we find that vov exposure is a significant determinant of hedge fund returns after controlling for fund characteristics we find a robust and significant negative risk premium for vov exposure in the cross section of hedge fund returns we corroborate our results using statistical and parameterized proxies of vov over a longer sample period

stabilization with exchange rate management stabilization programs in open economies typically consist of two stages in the first stage the rate of currency devaluation is reduced but the fiscal adjustment does not eliminate the fiscal deficit that causes growth of debt and loss of reserves making a future policy change necessary only later at a second stage is this followed by either an abandonment of exchange rate management or by a sufficiently large cut in the fiscal deficit we study how different second stage policy changes affect economic dynamics during the first stage these changes include tax increases budget cuts on traded and nontraded goods and increases in the growth rate of money

estimation of area elasticities from a standard profit function this article demonstrates that both crop area and output elasticities can be calculated from a profit function a chambers just profit function which includes land allocations as quasi fixed factors is used to derive shadow price equations for each crop area allocation jointly solving these shadow price equations for crop area makes it possible to calculate individual crop area elasticities a profit function is specified to represent agricultural producers in the state of iowa shadow price equations are jointly estimated with output supply and input demand equations from these estimated equations we derive the individual crop area response and output response to a change in prices

ambiguity and nonparticipation the role of regulation we investigate the implications of ambiguity aversion for performance and regulation of markets in our model agents decision making may incorporate both risk and ambiguity and we demonstrate that nonparticipation arises from the rational decision by some traders to avoid ambiguity in equilibrium these participation decisions affect the equilibrium risk premium and distort market performance when viewed from the perspective of traditional asset pricing models we demonstrate how regulation particularly regulation of unlikely events can moderate the effects of ambiguity thereby increasing participation and generating welfare gains our analysis demonstrates how legal systems affect participation in financial markets through their influence on ambiguity the author 2009 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oxfordjournals org oxford university press

current account effects of a temporary change in government expenditure a perfect foresight model of intertemporal utility maximization is used to analyze the current account effects of a temporary increase in government spending the relationship between the marginal utility of private consumption and the supply of public goods in the economy is shown to play a crucial role in determining the qualitative nature of the optimal current account response the link between the timing of the policy change and the magnitude of the current account effect is also examined

the ambiguity of earnings announcements we study the consequences of misreporting in settings where ambiguity averse investors face uncertainty about two aspects of the firm its productivity and the weakness of its reporting system we

earnings announcements and attention constraints the role of market design abstract we identify a new channel market makers attention constraints through which earnings announcements for one stock affect the liquidity of other stocks when some stocks handled by a designated market maker have earnings announcements liquidity is lower for non announcement stocks handled by the same market maker with the largest effects coming from earnings surprises and stocks with high earnings response coefficients half of the liquidity decline reflects attention constraints binding on the individual market maker and the other half is explained by the market maker s inventory we further find that a market design change that increases automation alleviates the liquidity effect of attention constraints despite an increase in the number of stocks allocated to each market maker

microstructure and ambiguity a goal for stock exchanges is to increase participation by firms and investors we show how specific features of the microstructure can reduce perceived ambiguity and induce participation by both investors and issuers we develop a model with sophisticated traders who we view as expected utility maximizers with rational expectations and unsophisticated traders who we view as rational traders facing ambiguity about the payoffs to participating in the market we show how designing markets to reduce ambiguity can benefit investors through greater liquidity exchanges through greater volume and issuing firms through a lower cost of capital
