longevity risk subjective survival expectations and individual saving behavior abstract we provide evidence of individuals awareness of longevity risk the uncertainty about future survival probabilities based on subjective survival expectations elicited in the survey of health ageing and retirement in europe share and matching data on longevity risk from the human mortality database we find a positive relationship between the forecast dispersion in subjective survival estimates and longevity risk which indicates that individuals are to some extent aware of longevity risk our analysis of savings behavior shows that the dispersion in survival estimates is primarily explained by individuals disagreeing on the survival probability and not by their true awareness of the underlying uncertainty individuals do not save more on average when faced with longevity risk although theory suggests they should

competition increases x efficiency a limited liability mechanism the main result of this study is that a financial constraint may serve as a disciplining device on the internal efficiency of a firm and the tougher the product market competition the higher the disciplining power this limited liability mechanism may in part account for the alleged disciplining power of product market competition on firm efficiency however even if policies that promote competition enhance x efficiency the gain may be outweighed by a less efficient allocation of risk moreover this adverse risk effect has repercussions implying that the effect of reduced entry barriers on competition and consumer s welfare is small

optimal price and inventory adjustment in an open economy model of the business cycle this paper presents a macroeconomic model containing optimizing inventory holding firms that is consistent with a number of prominent empirical regularities concerning fluctuations in output exchange rates relative prices and money prices are sticky but they are not predetermined still our model is consistent with exchange rate overshooting in the sense of dornbusch typical sticky price models allow a divergence between current production and current demand but this divergence is never allowed to feed back into the model our optimal inventory adjustments reconcile divergences between current demand and production and the inventory stock movements provide expected future dynamics

asset pricing with loss aversion using standard preferences for asset pricing has not been very successful to match asset price characteristics such as the risk free interest rate equity premium and the sharpe ratio to time series data behavioral nance has recently proposed more realistic preferences such as preferences with loss aversion to model asset pricing research has now started to explore the implications of behaviorally founded preferences for asset price characteristics encouraged by some studies of benartzki and thaler 1995 and barberis et al 2001 we study asset pricing with loss aversion in a production economy we here employ a stochastic growth model and use a stochastic version of a dynamic programming method with adaptive grid scheme to compute the above mentioned asset price characteristics of a model with loss aversion in preferences as our results show a model with loss aversion performs considerably better than pure consumption based asset pricing models

limited liability and incentive contracting with ex ante action choices abstract this article examines a principal agent model of financial contracting in which a risk neutral entrepreneur agent makes an unobservable ex ante effort choice while employing the investment funds of a risk neutral investor principal the key innovation is that the investment contract is subject to statutory liability limits given these liability limits two settings are considered one in which the investor payoff function is also constrained to be monotonically nondecreasing in firm profit and another in which no such monotonic contract constraint is imposed in the former case a standard debt contract is shown to emerge and a first best effort choice is not achieved in the latter setting the optimum is characterized by a live or die payoff function and a first best effort level may or may not be realized

competing macro hypotheses in the united states a kalman filtering approach the empirical validity of alternative views about the short run determinants of real output growth in the united states is investigated a nested framework is used to test the macro rational expectations mre hypothesis directly against two competing hypotheses the neo keynesian view that anticipated and unanticpated monetary policy both matter and friedman s 1977 proposition that increased inflation uncertainty reduces real output at least temporarily the unobservable explanatory variables are obtained from time varying parameter models of inflation and money growth which generate forecast errors and their conditional variances consistent with rational expectations under a continuously chaning policy regime the empirical results strongly support friedman s view the mre hypothesis must be rejected since both anticipated and unanticipated monetary changes matter the results prove robust across different model specifications and estimation techniques

information competition and markets one of the dominant characteristics of modern capitalist economies is the important role played by competition not the peculiar static form of pure price competition embodied in the arrow debreu model but rather a dynamic competition more akin to the kind of competition represented by sports contests and other races including patent races in recent years there have been several attempts to explain why firms often base the pay of their workers and managers on relative performance see for example edward lazear and sherwin rosen 1981 such compensation schemes become desirable when three conditions are satisfied a the input effort of workers managers must not be directly observable at least without cost thus firms must either expend resources to monitor inputs or devise reward structures in which compensation is a function of variables such as output or profits which are themselves functions of inputs but are less costly to observe b the relationship between input and output must be stochastic so that by observing output one cannot perfectly infer what the input was c finally the stochastic disturbances which affect the relationship between input and output of different firms must be correlated by looking at the performance of one worker relative to that of others one can make better inferences about his effort than one can make without using this information not only can competition provide a basis of comparison which enables the design of reward structures that can simultaneously provide a high level of incentives with relatively low level risk but compensation schemes based on relative performance have the further advantage of automatically adjusting incentives to changes in the economic environment we refer to this as built in flexibility in a first best world with perfect information concerning the nature of the technology but where it is still costly to monitor individuals activities the compensation scheme would vary from time to time as the environment changed such changes in the compensation scheme are costly to implement and the information required to do so is seldom available when a task is easier the individual s rewards for performing the task should be reduced if pay is based on relative performance although all individuals perform better when they exert the same level of effort their compensation is automatically adjusted thus teachers frequently grade on the curve and a significant fraction of the pay of successful salesmen often consists of bonuses based on relative performance

product market competition and managerial slack this article analyzes the effect of product market competition on managerial incentives in contrast to hart 1983a i show that competition may actually exacerbate the incentive problem the difference in results derives from our different assumptions about managerial preferences the importance of assumptions about preferences suggests that we do not yet understand the precise mechanism through which competition affects incentives

bargaining search and outside options abstract this paper studies a two sided incomplete information bargaining model between a seller and a buyer the buyer has an outside option which is modeled as a sequential search process during which he can choose to return to bargaining at any time two cases are considered in regime i both agents have symmetric information about the search parameters we find that in contrast to bargaining with complete information the option to return to bargaining is not redundant in equilibrium however the no delay result still holds in regime ii where agents have asymmetric information about the outside option delay is possible the solution characterizes the parameters for renegotiation and those for search with no return to the bargaining table

does trade liberalization promote regional disparities evidence from a multiregional cge model of india summary over last few decades there has been a growing interest among researchers in understanding the link between trade liberalization and regional disparities within the context of an individual country in this study we develop the first ever single country multiregional computable general equilibrium cge model for the indian economy to investigate this linkage overall our results suggest that in the short run trade liberalization has a beneficial impact on the rich and fast growing middle income states and a marginal or negative impact on the poor states

empirical measures of inflation uncertainty a cautionary note a direct ex ante measure of inflation uncertainty in the us is compared with a number of proxies used in empirical studies the direct estimate is the root mean subjective variance of the probability distributions for inflation reported by respondents to the asa nber survey the proxies include forecast standard deviations from arima arch and structural models of inflation these proxies are not significantly correlated with the direct measure nor with one another use of the proxies leads to incorrect inferences about the correlation between inflation and inflation uncertainty and between inflation uncertainty and the real interest rate

fairness price stickiness and history dependence in decentralized trade this chapter investigates the implications that social preferences have for the stationary strategic equilibrium of such a decentralized market agents are supposed to be averse to unfairly unfavorable as well as unfairly favorable deals in the spirit of fehr and schmidt 1999 but we stay rather close to standard individualistic preferences the negative weights on advantageous and disadvantageous deviations from what is considered as the fair benchmark are such that utility remains strictly increasing in own surplus share and in contrast to the original fehr schmidt model the fair split need not automatically be a 50 50 division any price between sellers cost and buyers willingness to pay may be the one which for whatever reasons is agents reference point in a given market this makes it possible to consider a more flexible notion of fairness than is usually done it is in line with cognitive dissonance theory from psychology and the noteworthy experiments of binmore et al 1991 1993 where subjects who were triggered to play different bargaining equilibria ended up considering very different surplus distributions as fair

unanticipated monetary growth output and the price level in latin america an empirical investigation abstract this paper provides statistical evidence on the response of real output and the price level to movements in unanticipated monetary growth for 16 latin american countries in the context of barro s version of the rational expectations natural rate theory arima p d q modeling of the growth rate of m2 is employed for each country and the residuals of the selected model utilized to estimate the parameters of the real output and price level equations careful attention is devoted to the autocorrelation structure of the residuals of the real output and price level equations the empirical results suggest that generally unanticipated monetary growth has positive effects on real output and negative effects on the price level such patterns however do not exhibit an unambiguous symmetric response

source of monetary growth uncertainty and economic activity the time varying parameter model a large body of research suggests that uncertainty is an important factor affecting economic activity most earlier research however fails to consider the possibility that uncertainty may affect the value of new information and economic activity differently depending upon its source the author first examines the importance of these different sources for modeling u s monetary growth uncertainty he then empirically relates different sources of monetary growth uncertainty to economic activity measured by real gnp the results suggest that different sources of uncertainty have different impacts on economic activity the results tend to confirm predictions arising in the literature on irreversible investment and uncertainty copyright 1993 by mit press

unanticipated money growth and unemployment post sample forecasts in the late 1970s robert j barro published what has since become a popular model of business fluctuations barro s 3 findings provide evidence advocating the short run neutrality of money under rational expectations forging an important empirical link to the theoretical studies of lucas 19 20 and sargent and wallace 33 the original barro unemployment model has received additional support from further statistical testing 5 6 15 despite criticisms and modifications some of which are considered in barro s 6 updated model these equations have inspired numerous empirical studies analyzing unanticipated effects of macroeconomic variables this paper examines post sample forecasts of barro s original 3 and revised 6 unemployment equations for the 1974 84 period mayer 23 24 harvey 13 179 80 and lovell 18 among many contend that the ability to successfully forecast outside of the sample period is an important criterion for evaluating model robustness this view is also reflected in a substantial body of studies including 10 25 26 29 39 which investigate the post sample predictive performance of macroeconomic models one year ahead forecasts indicate that the barro 3 6 equations accurately predict unemployment for the 1974 79 period during 1980 84 however the predictive performance of both models sharply deteriorates augmenting the barro models with interest rate volatility in accordance with the findings of evans 11 and tatom 38 considerably improves the overall forecasting ability this modification also rectifies the 1980s structural instability of the barro unemployment equations furthermore the basic conclusions of the seminal barro work are retained with this augmented model the results reveal that increases in interest rate volatility exert significantly adverse effects upon unemployment corroborating with the findings of evans 11 and tatom 38 still interest rate volatility could be overlooked in previous estimations of the barro or other models of business fluctuations due to the variable s relative constancy prior to 1979

financial market efficiency the decomposition of anticipated versus unanticipated money growth and further tests of the relation between money and real output note probably the most controversial empirical findings in macroeconomics in the last decade stem from robert barro s investigations into the relative effects of unanticipated versus anticipated money growth on unemployment and real output these studies generally proceed by decomposing observed money growth into what is defined to be its anticipated and unanticipated components and then test the restriction that only the unanticipated money measure has important effects for unemployment and real output in black box reduced form real side equations that include determinants of the natural rates of unemployment and real output as additional explanatory variables l the results of these tests for the annual postwar u s data generally cannot reject the hypothesis that only unanticipated money growth is important for the determination of aggregate real activity 2 anticipated money growth is found to be neutral for unemployment and real output these results are important because they give empirical support to the assertion that the apparent nonneutrality of observed money growth does not provide any firm basis for the efficacy of a systematic countercyclical monetary policy it should be clear that a crucial problem in testing for the neutrality nonneutrality of anticipated unanticipated money growth lies in developing an appropriate decomposition of observed money growth into its anticipated and unanticipated parts small 13 mishkin 8 and weintraub 14 among others have

monetary policy and inflation uncertainty in the united states and germany friedman s 16 proposition that increased inflation uncertainty may adversely affect real economic variables has received much attention over the last decade the theoretical arguments for such real effects are compelling however the empirical evidence on their presence and magnitude in different countries is mixed most results for the postwar u s economy strongly support the proposition 28 25 26 19 24 7 whereas it is generally rejected for the german economy 23 17 8 2 while a direct comparison of the u s and german results is difficult due to a lack of uniform sample periods data definitions estimation techniques and or measures of inflation uncertainty the evidence to date nevertheless suggests that the role of inflation uncertainty differs sharply between the two countries the question then arises what factor s can explain the difference one popular explanation is that the monetary authorities in the united states and germany respond quite differently to accelerating inflation 3 so that the behavior of uncertainty differs across countries 4 the u s federal reserve is often criticized for switching frequently between the primary policy goals of price stability and full employment possibly due to political pressures 21 30 since inflation is primarily a monetary phenomenon in the long run it is likely that such stop and go policies increase the uncertainty about future steady state inflation which in turn can adversely affect real output growth by reducing overall economic efficiency the german bundesbank on the other hand is reputed for its staunch and credible commitment to price stability which often takes precedence over other policy goals a more consistent and predictable

managerial incentives risk aversion and debt we investigate the risk choices of risk averse ceos following recent theoretical work we expect ceo risk aversion to be more pronounced in firms with high leverage or high default probability we find that the ceos of these firms reduce firm risk even in the presence of strong risk taking incentives our results are robust to controls for the sensitivity of ceo wealth to stock price changes firm risk determinants the endogenous feedback effects of firm risk on ceo incentives unobserved firm and market effects and debt governance the impact of ceo risk aversion is economically significant

equilibrium portfolios in the neoclassical growth model abstract this paper studies equilibrium portfolios in the standard neoclassical growth model under uncertainty with heterogeneous agents and dynamically complete markets preferences are purposely restricted to be quasi homothetic the main source of heterogeneity across agents is due to different endowments of shares of the representative firm at date 0 fixing portfolios is the optimal equilibrium strategy in stationary endowment economies with dynamically complete markets however when the environment displays changing degrees of heterogeneity across agents the trading strategy of fixed portfolios cannot be optimal in equilibrium very importantly our framework can generate changing heterogeneity if and only if either minimum consumption requirements are not zero or labor income is not zero and the value of human and non human wealth are linearly independent

trade liberalization and rural poverty work trade affects aggregate income and relative prices it alters investment and savings decisions and thus has intertemporal effects it may also alter tax revenues and public spending and its effects are conditioned by transport costs and location specific phenomena this makes simple measurement of the effects of trade very difficult and the attribution of causality almost impossible a problem that has long plagued the literature on trade and growth see baldwin for a survey attempts to measure the effects of trade on poverty in developing countries face additional challenges in that most of the poor are found in rural areas in farming and frequently outside of the formal economy with the consequence that their activities and incomes can be measured only very approximately the poor also reveal a frustrating to data gatherers at least tendency to move around in pursuit of job opportunities rigorous answers to important and controversial empirical questions such as whether trade liberalization reduces poverty have proved elusive

real interest rates anticipated inflation and unanticipated money a multi country study a bstractin this paper we examine real interest rate behavior in canada west germany the united states and the united kingdom using a model that yields a semi reduced form equation linking the real interest rate to monetary growth shocks anticipated inflation and expected inflation variance the estimator used in our analysis accommodates regressors from other regressions ensuring that accurate inferences are obtained in all countries we find that increases in anticipated inflation initially dampen real interest rates in addition a significant and negative relationship between unanticipated money shocks and real interest across all countries is discovered inflation variance typically exhibits little explanatory power

search for a monetary propagation mechanism abstract this paper examines a monetary propagation mechanism in an economy where exchanges in goods and labor markets involve costly search it is shown that an increase in the money growth rate increases steady state employment and output when the money growth rate is low but reduces steady state employment and output when the money growth rate is already high the model produces persistent hump shaped responses in employment and output to money growth shocks even when the shocks have no persistence the model also generates desirable features in job vacancy sales inventory and the velocity of money all these features emerge here in an economy with perfectly flexible prices and wages journal of economic literatureclassification numbers e40 e30

animal spirits financial crises and persistent unemployment this article uses a rational expectations model with multiple equilibrium unemployment rates to explain financial crises the model has equilibria where asset prices are unbounded above i argue that this is an important feature of any rational agent explanation of a financial crisis since for the expansion phase of the crisis to be rational investors must credibly believe that asset prices could keep increasing forever with positive probability i explain the sudden crash in asset prices that precipitates a financial crisis as a large shock to expectations that leads to a permanent increase in the unemployment rate

anticipated money inflation uncertainity and real economic activity this paper critically examines a number of maintained hypotheses that are necessarily being tested along with the basic notion derived from the rational expectations re formulation of lucas 1972 19 73 that only unanticipated money matters the trend stationary representation of secular real output of lucas and others is replaced by a difference stationary representation found by nelson and plosser 1980 to be consistent with u s historical data the impact of inflation uncertainty on real activity is considered attention is paid to possible mis measurement of agents ex ante anticipated money growth it is found that three alternative measures of anticipated money growth produce a stable impact on growth of output and employment contemporaneous and lagged values of unanticipated money growth have no significant additional explanatory power in the presence of any one of the three measures of anticipated money growth beyond this it is impossible to reject the hypothesis that the initial positive real impact of anticipated money is not temporary inflation uncertainty is found to act as a significant depressant of real economic activity in the presence of all tested combinations of anticipated and unanticipated money growth this abstract was borrowed from another version of this item

the equity premium in brock s asset pricing model abstract in this paper we combine dynamic programming methods with projection methods for solving stochastic growth models as an application of these methods we solve brock s asset pricing model with a variety of parameterizations we focused on finding parameterizations that result in an equity premium that is high relative to the variation in consumption we show both analytically and numerically that the equity premium can be higher in a production based asset pricing model than it is in the consumption based asset pricing model even when the real output level is the same in both models

fisher phillips friedman and the measured impact of inflation on interest a reply the purpose of this paper is to demonstrate that empirical findings which persistently appear to contradict the fisher hypothesis that the nominal rate of interest should rise by the full amount of an increase in anticipated inflation are due basically to a failure to control for changes in the real rate of interest that are associated with changes in anticipated inflation we are guided in our search for proper specification of a fisher equation by a simple general equilibrium model which is employed to derive the impact of a change in anticipated inflation upon nominal interest given the requirement that commodity money and labor markets remain in equilibrium in effect we depart from the empirical tradition which has grown up around testing of the fisher hypothesis that takes the real interest rate to be independent of anticipated inflation and argues that for anticipated inflation properly measured the data ought to support the fisher hypothesis 1

capital market equilibrium with externalities production and heterogeneous agents abstract the paper studies general equilibrium in an economy with externalities production and heterogeneous agents the model developed builds on brock brock w a 1982 asset prices in a production economy in mccall j j ed the economics of information and uncertainty university of chicago press chicago pp 1 43 and merton merton r c 1987 a simple model of capital market equilibrium with incomplete information journal of finance 42 483 510 it involves both a stock market and a market for loans together with negative externalities produced by a subset of firms importantly the technological production structure of the firms is reflected in the properties of the shares traded in the stock market agents are heterogeneous in their financial choices potentially discriminating against the firms producing a negative externality the model sheds light on the utility costs of the discriminating behavior and on the impact on the price of the stock issued by the firm which is responsible for the externality the model is used to study the factors which may magnify or reduce the impact of discrimination a set of discriminated firms may be seriously affected only if the discriminating investors command a large portion of overall wealth and or they do not represent important diversification instruments the model can be applied to understanding the effects of socially responsible investment whereby investors discriminate against companies belonging to some sectors which are perceived as socially dangerous or unethical

econometric issues in macroeconomic models with generated regressors the paper critically reviews the literature on the econometric issues raised by the use of generated regressors gr in empirical models the economic rationale for the use of gr is considered with examples being drawn from several macroeconomic examples including new classical macroeconomic ncm models which postulate monetary neutrality various estimation methods are discussed for models which include surprise or unexpected terms and the strengths and weaknesses of each approach are investigated drawing upon the work of mcaleer and mckenzie 1991 situations where the typically inefficient two step estimation 2se method will be efficient are highlighted problems of model misspecification and measurement errors are also investigated an empirical section highlights some of the dangers of using uncorrected 2se estimation results through a careful consideration of many recent attempts to test the ncm monetary neutrality hypothesis copyright 1993 by blackwell publishers ltd

competition long run contracts and internal inefficiencies in firms abstract internal reward structures in firms are often integral parts of their culture and are changed infrequently in comparison to decisions about e g prices this paper investigates how this feature of firm organization provides a mechanism through which product market competition affects firms internal efficiency the design of firms internal organization is modeled as a choice of an incentive structure between a principal and an agent with strategic implications for firm s competitive positions on the product market it is shown that contrary to popular beliefs there may be a negative relation between the competitiveness of the product market and effort incentives

exploring efficiency differences over time in the spanish banking industry abstract over the last 15 years the competitive conditions under which spanish banking firms operate have become much tighter deregulation has affected both banks and savings banks allowing them to expand geographically and to choose less regulation conditioned output mixes this paper analyzes how in these circumstances banking efficiency has been affected considering two specifications of output and analyzing the dynamics of the entire distribution not only mean and standard deviation results differ depending on the output definition but they show that in general efficiency scores exhibit dynamic patterns that only two moments of the distribution hardly capture in particular regardless of the output definition considered efficiency scores were more dispersed in 1985 and more concentrated in 1995 and there were substantial changes in firms efficiency relative positions as measured by transition probability matrices in addition the multi modality of the distributions has almost disappeared at the end of the period

managerial incentives and product market competition are imperfectly competitive leibenstein 1966 claims that there may be a substantial amount of x inefficiency where x inefficiency measures the degree to which actual profits depart from the maximum of profits that could be obtained if all operations in the firm were carried out at minimal costs he offers empirical evidence from case studies showing that the welfare loss due to organizational slack is of an order of magnitude bigger than the welfare loss due to monopolistic price distortions on imperfectly competitive markets these results support the common presumption that increasing competition reduces organizational and in particular managerial slack however this early literature does not offer a theoretical explanation for the link between competition and managerial incentives in particular it ignores the fact that managerial incentives can be affected by the design of an incentive scheme in this paper i derive the optimal incentive scheme for a manager as a function of the competitiveness of the environment in which his firm operates the basic impact of increased competition is that it reduces the profits of a firm this has two effects in the model first if a firm has high costs then the reduction of profits may be sufficient to render the firm unprofitable so the probability that it has to be liquidated goes up this unambiguously induces the manager of the firm to work harder for a cost reduction in order to avoid liquidation and to keep his job second the reduction in profits may affect

economic liberalization and indian economic growth what s the evidence india s growth and poverty performance over the last three decades has been a subject of great curiosity unlike the east asian countries india s growth spurt is not associated with exceptionally high domestic savings or foreign capital inflows or manufacturing exports so what triggered the change in the growth trajectory did the market liberalization policies of the 1990s help how have the initial conditions shaped the process and how has the indian model impinged on india s central problem of mass poverty this paper surveys the literature and offers its own assessment of the drivers of change jel i32 o13 o14 o15 o21 o47

the impact of natural gas price control in china a computable general equilibrium approach abstract this paper depicts the natural gas price control behavior of the chinese government in an imperfect competition market structure using a static cge model it simulates the effect of changes in natural gas price control policy on carbon emission and the economic effects in view of demand side and supply side based on the above we also analyze the carbon emission mechanism from economic and energy structure perspective the results show that an increase in natural gas price can reduce carbon emission or tends to cause a long term decline in the surplus profit rate of the natural gas industry moreover the increase in natural gas price may raise the cpi and reduce actual gdp and residents welfare on the contrary a decrease in natural gas price may reduce cpi and enhance resident welfare however the long term actual gdp will not increase but carbon emission will increase and the surplus profit rate of the natural gas industry may reduce in the short term and increase in the long term on the other hand both increase and decrease in natural gas prices may result in a decrease of the actual gdp level in the long term the elimination of price control in natural gas supply may increase actual gdp and residents welfare and reduce cpi meanwhile it may increase carbon emissions and improve the profitability of the natural gas industry

moral hazard and limited liability implications for the theory of the firm this paper presents a theory of the firm based on moral hazard in the provision of effort by an owner manager who borrows money in financial markets under conditions of limited liability the authors examine the relationship between the financial structure of the firm and the effort and output decisions of the owner manager results are reported concerning the determination of the firm s optimal financial structure and concerning the positive and normative implications of financial structure for pure competition and monopoly they also identify a strategic advantage from equity finance under cournot oligopoly copyright 1989 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the evolution of new industries and the determinants of market structure several empirical regularities concerning firm growth rates and industry firm size distributions have been developed by studying primarily mature industries the primary purpose of this article is to bring together and extend empirical regularities on the evolution of new industries and to use these regularities to gain further insight into the forces governing industry evolution to explain these regularities a model is constructed which emphasizes how factors governing the early evolution of industries may shape their market structure at maturity it stresses how chance events and exogenous factors that influence the number of potential entrants to the industry the growth rate of incumbents and the ease of imitation of industry leaders will influence the ultimate number and size distribution of firms in the industry

forecasting rational expectations and the phillips curve an empirical investigation abstract the rational expectations version of the phillips curve is empirically evaluated for switzerland using a wide variety of specifications it turns out that the results are highly sensitive to measurement of both the natural rate and expectations of nominal variables no reliable phillips curve seems to exist in addition information on the relative quality of different forecasting schemes is obtained for a number of important macroeconomic variables

on the adjustment speed of smes to their optimal capital structure the aim of this paper is to analyse the speed of adjustment of small and medium sized enterprises smes to the target leverage by applying a system gmm technique to spanish panel data collected during the period 1995 2005 we estimate a partial adjustment model in which both target leverage and speed of adjustment are simultaneously endogenized we provide empirical evidence on the determinants of target leverage and the speed of adjustment more specifically the rate of financial flexibility growth opportunities and size are positively related to the speed of adjustment whereas the distance to the optimal ratio of debt shows a negative impact our findings demonstrate that in terms of sample mean a high percentage of spanish smes adjust rationally to their target additionally the smes analysed appeared to be over levered and fairly motivated to adjust annual adjustment speed 26

technological competition uncertainty and oligopoly abstract in an oligopoly context the present technological choice of a firm which expects to receive private revelant information just prior to the uncertain market stage has both a flexibility value and a strategic commitment value in contrast to some common wisdom ideas we provide a natural two stage competition framework in which an increase in uncertainty always raises the commitment value of the technological choice of the firm and may decrease its flexibility value when the increased uncertainty takes the form of more variable beliefs the first result tends to reinforce therefore the findings of the strategic commitment literature under certainty

interest rate variability and economic performance some international evidence using data for short term and long term interest rates across a major group of industrial countries his paper studies the impact of interest rate variability on the cyclical behaviour of real output and the price level in these countries theory predicts that the increased variability of the interest rate stemming from a rise in the level of uncertainty has a negaive impact on he ouput demanded and supplied and in turn an ambiguous impact on the price level the empirical evidence is generally consistent with this prediction next the investigation attempts to shed some light on major sources of uncertainty underlying the interest rate variability focus in on he variability of monetary growth the exchange rate and the energy price some evidence on he relative contribution of these sources of uncertainty of the variability of the interest rate and in turn to the cyclical behaviour of real output and the price level across countries is provided

product market competition and organizational slack under profit target contracts in a framework a la martin 1993 we introduce a common component in the managers private information in order to address three related questions what is the impact of contracts that reward managers on the basis of realized profits on firms productive and allocative efficiency relative to cost target contracts how do these contracts shape the relationship between competition and organizational slack can we then explain the existing evidence of an inverted u shaped relationship between competition and cost reducing activities as documented in aghion et al aghion p bloom n blundell r griffith r howitt p competition and innovation an inverted u relationship the quarterly journal of economics 120 pp 701 728 2005 we show that profit target contracts introduce a horizontal contractual externality between the competing firms that mitigates organizational slack and improves upon productive efficiency relative to cost plus mechanisms moreover when executive compensations are conditioned on profits an inverted u shaped relationship between product market competition and managerial effort obtains finally we also show that when contractual instruments are endogenous i e when shareholders can choose between profit and cost target rules the equilibrium with profit target contracts always exists and is the only one that survives to standard refinements

international trade and the gender wage gap new evidence from india s manufacturing sector summary this study examines how increasing competitive forces from india s trade liberalization have affected women s relative wages and employment neoclassical theory implies that costly discrimination against female workers should diminish over time with increased competition we incorporate this idea into a theoretical model of competition and industry concentration and test the model using repeated cross sections of india s national sample survey organization nsso household survey data merged with trade and production data from 1983 to 2004 estimates from ordinary least squares ols and fixed effects regressions at the industry level indicate that increasing openness to trade is associated with larger wage gaps in india s concentrated manufacturing industries

welfare impacts of china s accession to the world trade organization data from china s national rural and urban household surveys are used to measure and explain the welfare impacts of changes in goods and factor prices attributable to accession to the world trade organization wto the price changes are estimated separately using a general equilibrium model to capture both direct and indirect effects of the initial tariff changes the welfare impacts are first order approximations based on a household model incorporating own production activities calibrated to household level data and imposing minimum aggregation the results show negligible impacts on inequality and poverty in the aggregate however diverse impacts emerge across household types and regions associated with heterogeneity in consumption behavior and income sources with possible implications for compensatory policy responses

an analysis of the principal agent problem most analyses of the principal agent problem assume that the principal chooses an incentive scheme to maximize expected utility subject to the agent s utility being at a stationary point an important paper of mirrlees has shown that this approach is generally invalid we present an alternative procedure if the agent s preferences over income lotteries are independent of action we show that the optimal way of implementing an action by the agent can be found by solving a convex programming problem we use this to characterize the optimal incentive scheme and to analyze the determinants of the seriousness of an incentive problem

the effects of competition on executive behavior economists presume that competition spurs a firm to be more efficient by forcing it to reduce its agency problems this article investigates this presumption it finds that the effects of competition on executive behavior can be decomposed into four effects each of which is of potentially ambiguous sign theory thus offers no definitive defense of this presumption this article also derives sets of conditions under which increased competition has the presumed effect of reducing agency problems in some sets important conditions are that increased competition reduce the executive s expected income and that agency goods e g shirking be normal goods for the executive the article shows that an increase in the shareholder bargaining strength can both reduce the agency problem and make it more sensitive to competition

do capm results hold in a dynamic economy a numerical analysis in this research we use the projection method reported by judd to find numerical solutions to the euler equations of a stochastic dynamic growth model the mode1 that we solve is brock s asset pricing model for a variety of parameterizations of the production functions using simulated data from the model conjectures which are not analytically tractable can be verified we show that the market portfolio is mean variance efficient in this dynamic context we also show a result that is not available from the static capm theory the efficient frontier shifts up and down over the business cycle

real business cycles and the lucas paradigm when the lucas paradigm is generalized to include real effects the effects of real factors and monetary factors on the business cycle are always interrelated furthermore in such models monetary factors can affect the long run behavior of real output contrary to the commonly held view that they cannot real business cycle models and lucas type models are different paradigms but not in the sense of real versus monetary rather interrelationships between real and monetary factors are intrinsic to the lucas paradigm whereas the real business cycle literature implies a dichotomy between real and monetary factors

impact of the information asymmetry between managers and owners under oligopoly we show using a hotelling 1929 model with laffont and tirole 1986 firms that under duopoly the information asymmetry caused by the separation of ownership and control has two effects on owners incentives to induce effort information asymmetry raises the marginal cost of inducing effort which decreases efforts and increases prices since all firms prices increase this leads to a change in the expected demand of each firm and thus in the marginal benefit of inducing effort which may amplify or mitigate the initial impact as a consequence information asymmetry may induce some firms to increase efforts and lower prices more surprisingly it may increase both ex post and ex ante social welfare

inflation uncertainty and real economic activity an alternative approach a bstracct increased uncertainty about inflation is shown to encourage inflation hedging which in turn reduces the macroeconomic costs of that uncertainty portfolio theory and empirical evidence support the contention that only the portion of inflation volatility that cannot be hedged has real economic effects additional empinrcal results suggest that i increased inflation volatility in the early seventies was eventually followed by portfolio reallocations that allowed for greatly improved inflation hedging and ii the deletenrous effect of inflation uncertainty on real economic activity shown in previouis studies is significantly smaller after 1975
