the effects of taxation price control and government contracts in oligopoly and monopolistic competition abstract many government contracts with or policies towards oligopolistic sectors essentially involve private firms selling a given proportion or quantity of output to the government at a fixed price p r with the remainder being sold on the open market often this is combined with consumer rationing examples include cement and sugar in india and health housing and defence in many countries the paper investigates the effects of these schemes including sales and excise taxation on prices output and household welfare under oligopoly and monopolistic competition less government control reduced may raise prices and tax shifting can be above or below 100 percent

inflation financial markets and long run real activity abstract empirical evidence suggests that real activity the volume of bank lending activity and the volume of trading in equity markets are strongly positively correlated at the same time inflation and financial market activity are strongly negatively correlated in the long run as are inflation and the real rate of return on equity inflation and real activity are also negatively correlated in the long run particularly for economies with relatively high rates of inflation we present a monetary growth model in which banks and secondary capital markets play a crucial allocative function we show that at least under certain configurations of parameters the predictions of the model are consistent with these and several other observations about inflation finance and long run real activity

stock markets and development this paper asks if financial development especially stock market development affects the level and or the growth rate of economic activity it finds a substantial effect on both current wisdom suggests that the growth effects of financial intermediation could be either permanent or transitory for instance the greenwood jovanovic 1990 henceforth gj model has an ak stucture with no diminishing returns to the reproducible factor and a permanent exogenous improvement in financial structure would cause a permanent increase in the rate of growth on the other hand if the returns to the reproducible factor did diminish better intermediation could lead only to level effects since one should not a priori exclude either growth effects or level effects we shall look for both our search for growth effects will use the gj model our search for level effects will rely on an amended version of the mankiw romer and weil 1992 henceforth mrw structure

reservation wages and the cost of unemployment this paper studies direct evidence on reservation wages reported in great britain in 1982 to assess 1 whether such asking prices are high and 2 whether variations in these reservation wages are related to differences in measures of the subjective and objective costs of unemployment a majority overall and for various subgroups reports reservation wages no higher than own past wages adjusted for earnings growth but there is nonetheless considerable dispersion in the ratio of reservation to past wages reservation wages are somewhat related to measures of the differential cost of unemployment most clearly for men although the independent role of benefits is often imprecisely measured however exactly which of these costs matter differs significantly according to whether the separation from last employment was voluntary or involuntary copyright 1989 by the london school of economics and political science

reemployment probabilities and returns to matching the assumption of constant returns in the matching function embodied in most bilateral search models is crucial to ensure the uniqueness of the unemployment rate along a steady state growth path this article explores the empirical viability of this assumption by estimating individual reemployment probabilities on a sample of unemployment entrants i apply hazard models to survey data on both completed and uncompleted unemployment durations the hypothesis of constant returns to matching is not rejected on the basis of the evidence that the job finding hazard depends only on local labor market tightness and is independent of its size

the economic effects of unemployment insurance in canada an empirical analysis of ui disentitlement this article provides an overview of the canadian unemployment insurance ui program including its evolution salient features relative size and knowledge about its labor market impacts understanding of these impacts is limited and we conclude that an event study approach is a promising way to further this knowledge we examine the effects of the 1976 ui disentitlement of the elderly on their labor force behavior and find evidence of significant adverse selection effects interactions with the public pension system suggest that poverty among the elderly could be best addressed through changes in programs other than ui

financial fragility and the exchange rate regime abstract we study financial fragility exchange rate crises and monetary policy in a model of an open economy with diamond dybvig banks the banking system the exchange rate regime and central bank credit policy are seen as parts of a mechanism intended to maximize social welfare if the mechanism fails banking crises and speculative attacks on the currency become possible we compare currency boards fixed rates and flexible rates with and without a lender of last resort a currency board cannot implement a social optimum in addition it allows bank runs to occur a fixed exchange rate system may implement the social optimum but is more prone to bank runs and exchange rate crises than a currency board a flexible rate system implements the social optimum and eliminates runs provided that the exchange rate and credit policies of the central bank are appropriately designed journal of economic literature classification numbers f3 e5 g2

stock market returns and inflation evidence from other countries this paper investigates the relation between common stock returns and inflation in twenty six countries for the postwar period our results do not support the fisher hypothesis which states that real rates of return on common stocks and expected inflation rates are independent and that nominal stock returns vary in one to one correspondence with expected inflation there is a consistent lack of positive relation between stock returns and inflation in most of the countries

the long run relationship between inflation and output in postwar economies abstract we investigate the relationship between inflation and real output in a large sample of postwar economies our methodology is to use a structural vector autoregression to estimate the response of the level of real output to permanent inflation shocks separately for each country we find that a permanent shock to inflation is not associated with a permanent movement in the level of real output for most countries in our sample the main exceptions are certain low inflation countries in which permanent inflation shocks permanently increase the level of output we also find that permanent inflation shocks do not permanently influence real output growth rates in our sample

how good are standard debt contracts stochastic versus nonstochastic monitoring in a costly state verification environment the authors investigate ex ante efficient contracts in an environment in which implementation is costless in this environment standard debt contracts will typically not be optimal optimal contracts may involve defaults even in states in which the borrower is fully able to repay the authors then examine the welfare costs of arbitrarily restricting the set of feasible contracts to standard debt contracts when model parameters are calibrated to realistic values the welfare loss from exogenously imposing this restriction is extremely small thus if implementation costs are actually nontrivial as seems likely standard debt contracts will be very close to optimal copyright 1994 by university of chicago press

costly monitoring financial intermediation and equilibrium credit rationing abstract this paper establishes a link between equilibrium credit rationing and financial intermediation in a model with asymmetrically informed lenders and borrowers costly monitoring and investment project indivisibilities intermediation is shown to dominate borrowing and lending between individuals and these financial intermediaries exhibit several of the important features of intermediaries as we know them equilibrium interest rates and the aggregate quantity of loans respond quite differently to changes in taste and technology parameters depending on whether or not there is rationing in equilibrium

the impact of the potential duration of unemployment benefits on the duration of unemployment abstract this paper examines the impact of the potential duration of unemployment insurance ui benefits on unemployment in the united states first we use a large sample of household heads to examine differences in the unemployment spell distributions of ui recipients and nonrecipients sharp increases in the escape rate from unemployment both through recalls and new job acceptances are apparent for ui recipients around the time of benefits exhaustion such increases are not apparent at similar points of spell duration for nonrecipients second our analysis of accurate administrative data from 12 states indicates that a one week increase in potential benefit duration increases the average duration of the unemployment spells of ui recipients by 0 16 to 0 20 weeks

banking sector development and interest rate volatility in emerging economies over the last decades macroeconomic stability is said to be one of the major concerns of emerging economies financial sector as a core of macroeconomic stability has been under close consideration of policy makers the relationship between interest rate uncertainty and banking sector development as one of the most important indicators of financial sector development especially for emerging economies has not received enough attention in the literature perhaps this article is the most comprehensive study that investigates the relationship between interest rate uncertainty and banking sector development for a large group of emerging economies to do this the short run and long run models using a bounds testing approach to cointegration for 12 emerging economies over the period 1980 2011 have been developed estimated results from all models indicate that interest rate uncertainty has significant effect on banking sector development in both short run and long run phenomena in the majority of countries

an equilibrium model of search unemployment this paper develops a simple general equilibrium model with sequential search in which a nondegenerate wage offer distribution is endogenously determined we use this model to analyze the comparati

does judicial efficiency lower the cost of credit the authors investigate the effect of judicial efficiency on banks lending spreads for a large cross section of countries they measure bank interest rate spreads for 106 countries at an aggregate level and for 32 countries at the level of individual banks the authors find that after controlling for a number of other country characteristics judicial efficiency in addition to inflation is the main driver of interest rate spreads across countries this suggests that in addition to improving the overall macroeconomic climate in a country judicial reforms through a better enforcement of legal contracts are critical to lowering the cost of financial intermediation for households and firms

unemployment duration unemployment benefits and labor market programs in sweden abstract standard search theory as well as some empirical evidence suggest that an unemployed individual s probability of entering employment increases as he approaches the time when unemployment benefits are due to expire this pattern may not carry over to a country like sweden where labor market programs are targeted at the long term unemployed at risk of benefit exhaustion the paper examines transitions out of unemployment using data on unemployed individuals in sweden a semi parametric competing risks model for transitions to employment labor market programs and non participation is estimated there is some evidence that the exit rate from unemployment to employment increases as benefit exhaustion is approached

financial markets the pattern of industrial specialization and comparative advantage evidence from oecd countries due to underlying technological and organizational differences industries differ in their need for external finance since services provided by the financial sector are largely immobile across countries the pattern of industrial specialization should be influenced by the level of financial development among oecd countries we find a strong causal effect of the financial sector on industrial specialization further the financial sector is a source of comparative advantage in a way consistent with the hecksher ohlin vanek model results are also presented on which aspects of financial systems are important for specialization and comparative advantage

an econometric analysis of reservation wages this paper describes an analysis of survey data on unemployed people who reported their asking wage and the wage they expected to earn we show that if agents behavior is described by the standard optimal job search model one can use these data to deduce structural parameters rather than estimate them and we report our deductions from two surveys 1 of british unemployed people

monitoring the monitor an incentive structure for a financial intermediary this paper studies financial intermediation i e delegated monitoring in a costly state verification model there are a finite number of agents thus the intermediary cannot fully diversify its portfolio and is subject to default risk the role of the intermediary is to satisfy simultaneously the different portfolio preferences of borrowers and lenders two questions arise when a delegated monitor is subject to non trivial default risk a what arrangement solves the problem of monitoring the monitor b what intermediary portfolio accomplishes optimal asset transformation between borrowers and lenders unlike previous delegated monitoring studies the law of large numbers is not sufficient to obtain our results instead we appeal to a stronger results the large deviation principle which establishes that convergence in the law of large numbers is exponential

eefects of reintegration activities on the dutch labour market regarding levels of education in the netherlands during the early nineteen nineties social security administration offices and labour exchange offices decided to co operate goal of this cooperation is to support the reintegration of unemployed people into the labour market and to shorten the individual spells of unemployment as a result of the cooperation information is available about levels of education of the unemployed this article primarely focuses on the effects of reintegration activities on the duration of unemployment for different levels of education results of the analysis are compared with the human capital theory also the question is discussed whether within the framework of the cooperation persons with a higher level of education have shorter spells of unemployment finally there is an analysis of the effects of activities undertaken by the unemployed themselves to find a job people with a university degree have significant longer spells of unemployment the reintegration activities of the social security administr

indivisible labor lotteries and equilibrium abstract this paper considers an economy where labor is indivisible and agents are identical although the discontinuity in labor supply at the individual level disappears as a result of aggregation it is shown that indivisible labor has strong consequences for the aggregate bahavior of the economy it is also shown that optimal allocations involve lotteries over employment and consumption

the effects of unemployment compensation in general equilibrium with search unemployment it is shown that when the effects of an increase in unemployment subsidies are studied in a general equilibrium framework unemployment increases far less than in a partial partial model in fact the result may very well be a decrease in unemployment if the general equilibrium forces are strong enough in the model used in this paper an increase in unemployment compensation unambiguously decreases the rate of unemployment copyright 1990 by the editors of the scandinavian journal of economics

on earnings related unemployment benefits and their relation to earnings an aspect of unemployment in britain that has been much discussed in recent years is the possible disincentive effects of unemployment benefits paradoxically the actual pattern of receipt of those benefits is hardly considered at all one reason for this is the popular belief that actual receipt follows a well defined hypothetical pattern this belief is encouraged by the government s representation of the benefit system for instance the department of health and social security dhss regularly publish hypothetical calculations of benefit receipt e g social security statistics i982 table 46 i4 and government answers to parliamentary questions are typically based on these figures economists frequently take these hypothetical calculations at face value when trying to model the effect of unemployment benefits on labour supply in a time series framework or in the case of micro analysis make similar calculations for each individual in the data set calculations are based on a limited set of stylised rules which are considered to capture the essence of the workings of the benefit system however estimates of the disincentive effects of benefits do not appear to be robust to the method of calculation atkinson et al i984 this emphasises the need for more precise modelling of the determinants of benefit receipt this paper is concerned with modelling the receipt of the benefit that has been at the heart of the incentives debate earnings related supplement ers was the element of national insurance unemployment benefit in the united kingdom that was linked to some measure of past earnings several commentators in the mid1 970s purported to show that its introduction in i 966 led to a marked rise in unemployment in the late i96os e g maki and spindler i975 and its abolition under the i980 social security no 2 act was certainly due in part to the belief that it discouraged work in investigating the receipt of this benefit the paper provides a case study of the difficulties in modelling the incomes of the unemployed and a cautionary tale to any investigator who does not have all the information necessary for precise calculation of budget constraints the typical assumption that has been made when simulating ers in micro data sets of unemployed individuals is that the relevant earnings that generate an ers payment may be successfully proxied by normal weekly earnings immediately prior to unemployment we may call this proxy the hypothetical model of ers receipt and the focus of the analysis is a test of this model using data on

macroeconomic adjustment and poverty in selected industrial countries the business cycle affects the incidence of poverty as shown by evidence from australia sweden the united kingdom and the united states many of the poor in these countries are outside the labor markets and transfers are a major source of income for many others but the unemployment and wage reductions that occur in recession increase the incidence of poverty major causes of poverty are unemployment in australia and the united kingdom and low wages in the united states similar cyclical effects are observed in sweden but a vast transfer program virtually eliminates poverty there are several policy options for combating poverty caused by recession a combination of unemployment insurance for a limited period followed by a job guarantee is the most effective policy toward unemployment whereas poverty caused by low earnings can be remedied by redistribution through the tax system

cross country evidence on long run growth and inflation i introduction many believe inflation has important adverse effects on long run economic performance this conviction is based on the logic summarized by fischer and modigliani 1978 for example that firms and workers devote productive resources to dealing with inflation that inflation uncertainty reduces efficiency by discouraging long term contracting and increasing relative price variability and so on nonetheless many others believe that the magnitudes of such costs are small and insignificant at moderate rates of inflation cross country growth regressions would seem to offer a sensible means of empirically determining inflation s effects 1 such analysis would appear less sensible however in light of the levine and renelt 1992 finding that estimates of the growth inflation relationship vary sharply with the regression specification nonetheless analyses completed subsequent to levine and renelt 1992 for example fischer 1991 1993 cozier and selody 1992 and cukierman et al 1993 continue to use growth regressions to infer inflation s effects and typically conclude growth and inflation to be inversely related this paper shows that while inflation does generally appear to be inversely related to growth estimates of the relationship suffer two additional robustness problems problems which emerge across a variety of model specifications more specifically this analysis first demonstrates the sensitivity of growth inflation results to modifications to the sample of countries limited from the start to low and moderate inflation countries it next demonstrates the sensitivity of results to modifications in the time period for example among oecd countries abbreviating the covered time period from 1960 85 to 1968 85 reduces inflation s effect on growth to insignificance such fragility with respect to the country sample and time period may be viewed as even more fundamental than the regression specification sensitivity documented by levine and renelt 1992 this analysis then shows that the same robustness problems plague alternative specifications of the growth inflation relationship the baseline regression estimated here supposes a linear growth inflation relationship formally it follows from an augmented solow growth model 1956 in which inflation drives the level but not the growth rate of steady state income plausible alternatives include allowing inflation to have non linear effects on growth as in log and quadratic specifications and respecifying the model such that inflation formally drives steady state growth rather than just the steady state level of income such alternatives to the baseline specification yield results which suffer the same basic difficulties of sensitivity to country sample and time period ultimately these findings should further discourage that is lay to rest the practice of quantifying inflation s effects with cross country growth regressions while cross country growth regressions may be viewed as generally suggesting that inflation imposes costs the fragility of the estimates indicates researchers will need to use alternative approaches to better identify inflation s costs researchers might for example find it productive to build on the investment analyses of huizinga 1993 and pindyck and solimano 1993 which combine time series and cross section variation ii theory as detailed by mankiw romer and weil 1992 the solow growth model 1956 augmented to allow for human capital may be used to derive a simple relationship between growth and initial income population growth and the rates of physical and human capital investment 1 ln y sub i t y sub i 0 gamma sub 0 gamma sub 1 ln y sub i 0 gamma sub 2 ln n sub i g delta gamma sub 3 ln s sub i gamma sub 4 ln h sub i v sub i the variable y denotes income per capita n represents exogenous population growth g denotes the exogenous rate of growth of labor augmenting technology delta is the common rate of depreciation of physical and human capital and s and h denote respectively the rates of physical and human capital accumulation

who is credit constrained in the u s economy an important assumption of the life cycle model of consumption is the postulate of perfect capital markets this hypothesis has recently been challenged by substantial empirical evidence hall and mishkin 1982 using the panel study of income dynamics estimate that 20 percent of united states families are liquidity constrained mariger 1986 derives a life cycle model with endogenous liquidity constraints and using a cross section estimates this fraction to be 19 4 percent hubbard and judd 1986 simulate a model with a constraint on net worth which shows that with reasonable assumptions about preferences 19 0 percent of united states consumers are liquidity constrained the emerging consensus points therefore to a fraction of approximately 20 percent of the population behaving in a manner that is inconsistent with the pure life cycle model in addition hayashi 1985 and zeldes 1989 investigate the correlation among consumption wealth and income for various population groups and infer that liquidity constraints are more important for younger families with low levels of wealth and saving the main limitation of these studies is that in their data sets constrained consumers are not observable and have to be identified via indirect evidence thus there is as yet little firm evidence about the characteristics of the consumers who are likely to be credit constrained this paper adopts an approach that differs from previous tests for liquidity constraints because it makes use of data where constrained consumers are observable and explicitly links their existence to credit market imperfections and personal characteristics the data drawn from the 1983 survey of consumer finances scf and described in section ii provide information on individuals whose request for credit has been rejected by financial intermediaries in section iii a model is developed in which consumers and lenders behavior jointly determines the probability that a consumer is rationed in the credit market this probability is then

liquidity risk and financial competition implications for asset prices and monetary policy abstract this paper studies the implications of banking competition for capital markets and monetary policy in particular i develop a two sector monetary growth model in which a group of agents is exposed to liquidity shocks and money is essential banks insure depositors against such risk and invest in the economy s assets in this setting i compare an economy with a perfectly competitive banking sector to an economy with a fully concentrated financial sector unlike previous work banks can have market power in both deposits and capital markets compared to a perfectly competitive financial sector i demonstrate that a monopolistic banking system can have substantial adverse consequences on capital formation assets prices and the degree of risk sharing furthermore multiple steady states can emerge and the economy becomes subject to poverty traps more importantly market power in financial markets may overturn the tobin effect present under a perfectly competitive financial sector this necessarily happens in economies with high degrees of liquidity risk and low levels of capital formation

currency elasticity and banking panics theory and evidence existing models of banking panics contain no role for monetary factors and fail to explain why some banking systems experienced panics while others did not a monetary model is constructed where seasonal variations in the demand for liquidity and credit play a critical role in generating banking panics these panics occur when there are restrictions on the issue of currency in private banks but they do not occur if banks are unrestricted empirical evidence from canada and the united states for the period 1880 1910 is largely consistent with the predictions of the model

unemployment duration and competing risks evidence from sweden the determinants of unemployment duration are studied in the presence of multiple exits out of unemployment the results indicate that state aggregation may be a severe problem in empirical analysis of a labor market such as the one in sweden estimating a joint model for all transitions out of unemployment leads to biased estimates since different transitions are governed by different mechanisms the results also indicate positive duration dependence in both transitions to regular employment and transitions out of the labor force but no duration dependence in transitions to public labor market programs i introduction during the last decade we have witnessed a rapidly expanding literature on the determinants of unemployment duration the main motivation for this development is that a large share of the increasing unemployment rates in most western economies since the mid 1970s may be attributed to increased unemployment duration see e g the survey by lofgren and engstrom 1988 most empirical studies formulate an estimating equation for the determinants of the outflow from unemployment in terms of the hazard function which describes the conditional probability of leaving unemployment these studies are typically based on an explicit or implicit assumption that the only relevant transition out of unemployment is reemployment in this paper it is argued that such an assumption which amounts to assuming that all transitions from unemployment are governed by the same mechanism may lead to state aggregation bias we have no a priori reason to believe that e g increased education has the same effect on transitions from unemployment to employment as on transitions from

the impact of the international coffee agreement on producing countries the main objective of this article is to analyze the impact of the international coffee agreement s export system on the world coffee market focusing on increases in real export revenues transfer benefits and reductions in income variability risk benefits in each exporting country over the recent period of operation of the international coffee agreement s export quota system the authors find that the quota system had a stabilizing effect on world coffee prices the quotas reduced real export revenues for most small exporting countries but large producers gained most small countries gained however in terms of risk reduction if a brief suspension of the quota occurs from time to time caused for example by adverse weather which results in a shortfall in world supply the quota system works like a buffer stock scheme on average producing countries as a whole lose transfer benefits but gain risk benefits

inflation tax rules and investment some econometric evidence this paper presents econometric evidence on the effect of tax incentives on business investment in the united states in the period from 1953 through1978 the analysis emphasizes that the interaction of inflation and existing tax rules has contributed substantially to the decline of business investment since the late 1960 s because the investment process is far too complex for any simple econometric model to be convincing i have estimated three quite different models of investment behavior the strength of the empirical evidence rests on the fact that all three specifications support the same conclusion more generally the analysis and evidence show that theoretical models of macroeconomic equilibrium should specify explicitly the role of distortionary taxes especially taxes on capital income the failure to include such tax rules can have dramatic and misleading effects on the qualitative as well as the quantitative properties of macroeconomic theories this paper was presented as the fisher shultz lecture at the fourth world congress of the econometric society 29 august 1980 in aix en province this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this abstract was borrowed from another version of this item

financial market frictions monetary policy and capital accumulation in a small open economy abstract we consider a small open economy with a costly state verification problem and binding reserve requirements the presence of these frictions leads to the existence of two steady states with credit rationing an increase in the money growth rate the world interest rate or reserve requirements raises lowers gdp in the high low activity steady state however sufficiently large increases in money growth or the world interest rate can transform the high activity steady state from a sink to a source the model also delivers prescriptions for restoring the stability of this steady state in such an eventuality journal of economic literatureclassification numbers e5 f4

unemployment insurance and involuntary unemployment the case of adverse selection abstract this paper studies the private and public provision of unemployment insurance in a model where equilibrium unemployment results from the use of the wage as a worker selection device it is shown that private provision will not occur essentially because those workers most desired by a firm place least value on such coverage respecting the same informational constraints public provision necessarily gives rise to some distortions in participation decisions but nonetheless is welfare improving in the aggregate

search behaviour transitions to non participation and the duration of unemployment using longitudinal micro data on unemployed individuals for 1983 85 a structural job search model is estimated the model allows for transitions from unemployment to nonparticipation an extended version of the model deals with the influence of on the job search and prospective wage increases on search behavior of the unemployed the empirical results show that the probability of accepting a job offer is almost one for most unemployed individuals a large portion of unemployment spells ends in a transition out of the labor force the effects of changes in benefits on duration appear to be extremely small copyright 1990 by royal economic society

when to dollarize implicit in the debate over dollarization are two very different views of the sequencing of policy measures one view is that dollarization to work smoothly and yield more benefits than costs must wait on the completion of complementary reforms the other view is that dollarization need not wait on these other reforms because the very act of dollarizing will produce the changes needed to smooth the operation of the new regime in this paper i consider these arguments as they apply to the cases of labor market reform fiscal reform and financial sector reform i conclude that neither theory nor evidence suggests that removing all scope for an independent monetary policy will necessarily accelerate the pace of reform

how does the benefit effect vary as unemployment spells lengthen summary this paper investigates how the effect of income while unemployed on the probability of an individual leaving unemployment varies with the length of time that the individual has been unemployed we examine this question in the context of a variety of alternative econometric models we extend the proportional hazards model with unrestricted baseline hazard to one in which there are unrestricted effects of a subset of the explanatory variables and also consider models that can be estimated as series of binary response models the proportional hazard restrictions are rejected for the sample of british unemployed men analysed and in the binary sequence framework logit and probit models based on symmetric distributions dominate in likelihood terms the extreme value form model implied by extension of the proportional hazards formulation logit models with a flexible form for the duration dependence which also incorporate unobserved heterogeneity in a flexible way are estimated the results for all formulations indicate a rapidly declining effect of unemployment income as a spell lengthens with no significant effect for the long term unemployed the preferred specifications which allow for omitted heterogeneity indicate no significant effect after about 5 months and this result is robust to the inclusion or exclusion of previous labour market experience variables and to the choice of mixing distribution

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

money banking and capital formation we consider a monetary growth model in which banks arise to provide liquidity in addition there is a government that issues not only money but interest bearing bonds these bonds compete with capital in private portfolios when the government fixes a constant growth rate for the money stock we show that there can exist multiple nontrivial monetary steady states one of these steady states is a saddle while the other can be a sink moreover paths approaching a steady state can display damped endogenous fluctuations and development trap phenomena are common across different steady states low capital stocks are associated with high nominal interest rates the latter signal the comparative inefficiency of the financial system also increases in the steady state inflation rate can easily reduce the steady state capital stock journal of economic literatureclassification numbers e13 e44 e50 g20 o16

on limiting the market for status signals abstract in many societies individuals care how others view them in their efforts to impress such individuals engage in consumption signals which attempt to establish higher levels of status than their true status type this leads to an inefficiency which offers the possibility of a pareto improving tax policy the impacts of tax policy and benefits on the signalling equilibrium are considered

do coffee roasters benefit from high prices of green coffee abstract the german coffee industry has repeatedly made the puzzling statement that it would prefer higher prices of green coffee its main input likewise it supported the maintenance of the coffee tax in this paper an oligopoly model with differentiated products is used to illustrate the possibility of profit raising cost increases the relationship between prices and costs of roasted coffee in germany is estimated and the hypothesis of overshifting is tested in addition the demand for coffee is studied however the empirical analysis does not confirm that increasing costs lead to higher profits alternative explanations for the coffee industry s statements based on long term considerations are also discussed

searching for a will o the wisp an empirical study of the nairu in canada abstract this paper demonstrates the uncertainty surrounding estimates of the non accelerating inflation rate of unemployment nairu a reduced form phillips curve is used to develop a generic model of the nairu which nests competing hypotheses about the specific form of the inflation unemployment relationship empirical results for the canadian economy show that the range of prime age male nairu s generated by statistically satisfactory and economically reasonable estimating equations covers almost the entire range of canadian post war prime age male unemployment experience estimates of the nairu depend heavily on the form of the estimating equation the operational definition of key variables and the data sample period

interest margins and bank regulation in central america and the caribbean abstract this paper examines empirically the determinants of bank interest margins in central america and the caribbean over the period 1998 2014 a particular focus is set on the impact of differences in the regulatory environment and market structure across countries in explaining the interest margins of individual banks our results suggest that bank market power operating costs credit risk and liquid asset holdings increase the margin between loan and deposit rates while increased income diversification and gdp growth are associated with lower loan deposit spreads when considering information on banking regulation we find strong evidence to support our main hypothesis that improvements in market quality and liberalization have a significant effect on interest margins more specifically reductions in entry requirements to banking higher involvement of foreign banks and increased financial statement transparency are associated with significant reductions in interest margins

reforming the labour market there is nothing new about government attempts to reform the labour market the primary emphasis put upon this aspect of economic policy by the two conservative gov ernments since 1979 however is perhaps unique this emphasis is in part the conse quence of a new stress on supply side economics and of a belief that many imperfections in the labour market are in fact removable by a mixture of measures de signed to alter the attitudes of both institutions and individuals and the environment in which they operate having been shocked into heightened receptiveness by the re cession actors and institutions have been regaled by a variety of measures these in clude trade union and industrial relations legislation the abolition of the fair wages resolution a review of wages councils measures on social security benefits initiatives on training and mobility incentives for individual and community enterprise and schemes to reduce the size of the effective labour force

costly monitoring loan contracts and equilibrium credit rationing this paper develops a model with asymmetrically informed agents and costly monitoring of loan contracts where an equilibrium can exhibit credit rationing borrowers are identical ex ante but some receive loans and others do not in contrast to existing credit rationing theories rationing does not occur here due to inflexible prices adverse selection or moral hazard optimizing behaviour produces a standard debt contract in equilibrium the aggregate quantity of loans and equilibrium interest rates respond differently depending on whether there is rationing in equilibrium

competition in the swedish coffee market 1978 2002 abstract are multinationals exploiting their market power in national coffee markets by keeping consumer prices too high and thereby limiting demand for imports of coffee beans the purpose of this study is to address this issue by testing if there is market power in the swedish market for roasted coffee the market structure is typical of many consumer markets for coffee with four very large roasting companies two of which are multinationals plus many small ones to analyze the degree of market power an oligopoly model is estimated using market time series data the econometric approach is to first test for long run relationships between the variables with cointegration analysis and then to estimate a system of equations for demand and pricing behavior our key finding is that there is evidence of some market power in the short run but none in the long run

search models and applied labor economics individual effects in a nonlinear model explicit treatment of heterogeneity in the empirical job search model this paper extends the empirical version of a job search model to permit heterogeneity in the location of wage offer distributions population variance in wage offers is decomposed into variance due to heterogeneity and variance facing each individual heterogeneity is found to be an important source of offer variance in the population the amount of pure wage offer dispersion facing individuals is found to contribute little to population variance

do fair trade and eco labels in coffee wake up the consumer conscience abstract in this study a face to face survey was conducted in order to reveal consumer preferences for ethical and environmentally sound labeling programs in coffee valuation questions regarding the fair trade shade grown and organic coffee labels were asked using a payment card format after consumers were previously informed about each of the labeling programs results suggest that consumers are very receptive toward both fair trade and shade grown coffee labels and consequently are willing to pay higher premiums for these labeling programs than for the organic coffee

responding to the coffee crisis what can we learn from price dynamics an econometric model of coffee price dynamics is specified and estimated to capture the evolution of coffee prices at the farm wholesale and retail levels it investigates the historical influence of the international coffee agreement ica through its effects on yield and planting decisions in the short run the ica caused brazilian farm prices to become disconnected from international prices the ica helped coffee producers to better incorporate current world price information into planting decisions this created a price cycle that did not exist in non ica periods the low coffee prices experienced since the disintegration of the ica are consistent with low supply response to price information asymmetric price transmission at the retail level helped roasters and retailers benefit from upstream price interventions our results urge caution when considering future coffee price interventions

transactions costs technological choice and endogenous growth abstract hicks a theory of economic history clarendon press oxford 1969 argues that an important aspect of industrial development is the adoption of technologies requiring highly illiquid capital investments the adoption of such technologies becomes economically viable in the presence of low cost financial markets that provide liquidity to investors this observation provides a mechanism by which the costs of transacting in financial markets affect the equilibrium choice of technology productive efficiency and by implication growth we analyze how the costs of financial market transactions affect the set of technologies in use and the equilibrium growth rate transactions cost reductions may depending on the capital structure enhance or reduce growth journal of economic literature classification numbers d90 e13 g14

conspicuous consumption snobbism and conformism abstract we develop a model in which consumers purchase a conspicuous good in order to signal high income and thereby achieve greater social status in equilibrium the signalling value of conspicuous consumption depends in an identifiable way on the number of consumers and consumer behaviour is characterized by either snobbism or conformism the market demand curve for the conspicuous good may exhibit a positive slope if consumers are conformist we derive some unconventional policy implications concerning the taxation of luxuries and the voluntary provision of public goods

unemployment duration and individual heterogeneity a regional study this paper investigates the impact of individual heterogeneity and regional influences on unemployment duration utilizing cross section microeconomic data drawn from a representative random survey of individual job seekers for the english county of kent these individual level data are unique in that they provide information concerning the personal characteristics of job seekers alongside direct observations of both their reservation wages and job search behaviour such data are rare and to the authors knowledge have never before been utilized in a regional context thus the paper contributes to the empirical literature by analysing the extent to which individual heterogeneity and intra regional variation in labour market opportunities impact upon the observed distribution of unemployment duration s in particular the paper analyses the extent to which the duration of unemployment is determined by individual choice this is an important issue for the formation and evaluation of policy these result

demand for coffee in sweden the role of prices preferences and market power there is a widespread belief that consumer coffee prices are high relative to bean prices and that lower consumer prices would lead to substantial increases in bean exports from third world countries this issue is evaluated by analysing how retail prices preferences and market power influence coffee demand in sweden a demand function is estimated for the period 1968 2002 and used together with information on import prices of coffee beans to simulate an oligopoly model this approach gives estimates of the maximum average degree of market power and shows how coffee demand would react to reductions in marginal cost to its minimum level the maximum level of market power is found to be low but it generates large spreads between consumer and bean prices because the price elasticity has low absolute values moreover the impact of a price decrease would be small because long run coffee demand is dominated by changes in the population structure in combination with different preferences across age groups hence a change to perfect competition would only have a negligible effect on bean imports

the cyclicality of price cost margins in banking an empirical analysis of its determinants i introduction in this paper we study the cyclical behavior of price cost margins in banking calculated as the difference between the interest rate on loans and deposits using time series quarterly data for the period 1979 2005 in the united states this cyclical behavior of banks price cost margins a key fact about business fluctuations has received little attention before dueker and thornton 1997 find evidence that in cyclical downturns banks opt for a relatively high price cost margin however they focus exclusively on the markup of the bank prime lending rate over the marginal cost of funds for banks mandelman 2006 presents evidence on the cyclicality of margins for a large sample of countries and uses foreign bank penetration to explain the behavior of margins 1 in olivero 2005 aliaga diaz 2006 and aliaga diaz and olivero 2010a we document the countercyclicality of banks price cost margins in the united states in that paper we do so using an atheoretical methodology based on var forecast errors to measure comovement between variables 2 in this paper we build on this atheoretical evidence and take a step further by constructing an empirical model of the determinants of the cyclical behavior of margins here we take a theory based approach to decide on the inclusion of the relevant regressors that belong to this model doing so allows us to contribute to the literature by providing potential explanations for the previously documented countercyclical nature of margins monetary policy and credit risk could be suggested as the main and potentially the only determinants of the cyclical behavior of margins on the one hand the bank lending channel of monetary transmission predicts that the federal funds rate as a monetary policy indicator and margins are directly related therefore if policy rates exhibit a particular cyclical behavior not controlling for monetary policy could bias the estimations on the cyclical behavior of margins on the other hand credit risk is expected to be countercyclical and to raise margins so that default should help explain the countercyclicality of the latter based on these two observations our empirical methodology consists of two steps in a first step we test whether the negative and significant contemporaneous sample correlations between margins and a business cycle indicator are robust to the inclusion of controls related to monetary policy default risk and banking regulation results show it is so that there seems to be other channels through which fluctuations in the economy give rise to the observed countercyclicality of margins in a second step we look for these channels and offer several potential explanations for the observed behavior interest rate risk the economy s financial depth banks liquidity and capitalization and the share of total assets held by large banks all exert a significant impact on the behavior of margins over the business cycle these conclusions are consistent across alternative definitions of the margins and the business cycle indicator our work is linked to two strands of research in macroeconomics first our countercyclicality results are linked to the large literature on countercyclical markups in goods markets and its effects on aggregate demand started by rotemberg and saloner 1986 and rotemberg and woodford 1992 second price cost margins that vary endogenously and countercyclically in response to the state of the economy are a necessary condition for the existence of a financial accelerator as an amplifier of business fluctuations see for example bernanke and gertler 1989 and bernanke gertler and gilchrist 1998 therefore the countercyclical nature of price cost margins that we study here provides empirical support to the large body of literature in macroeconomic theory on this financial accelerator with price cost margins in the market for credit being countercyclical credit becomes more expensive in bad times firms may delay investment and production as a result and recessions may be exacerbated

introduction context issues and contributions from the asian financial crisis the russian default and the brazilian devaluation argentina s president menem recommended that his country officially replace the peso with the u s dollar motivating this proposal was a desire to strengthen the credibility of argentine monetary arrangements although argentina had maintained a currency board since 1991 interest rate differentials between peso denominated and dollar denominated debt widened during periods of financial turmoil indicating that the market perceived a significant probability of devaluation menem s proposal which closely followed the successful inauguration of the european monetary union stirred interest throughout the americas particularly in mexico and a year later in ecuador to some dollarization in mexico offered a guarantee against periodic peso devaluation and seemed a reasonable adjunct to the north american free trade agreement others howevel cited four years of relatively low exchange rate volatility and a reduction in the mexican inflation rate as support for current arrangements an independent central bank and a floating peso ecuador s president jamil mahuad announced his intentions to dollarize in january 2000 as a means of restoring monetary credibility to a battered economy although 80 percent of ecuadorian assets are already dollar denominated the decision prompted rioting these events illustrate the importance of a perennial question in open economy macroeconomics what type of monetary and exchange rate arrangements best promote the economic welfare of a country robert mundell 1961 first posed the question when he attempted to define an optimal currency area oca his work produced a rich debate within the economics profession ishiyama 1975 but seemed to have only a tangential influence on the policy debates of the 1960s and 1970s a period of limited international capital mobility as capital mobility in

veblen effects in a theory of conspicuous consumption the authors examine conditions under which veblen effects arise from the desire to achieve social status by signaling wealth through conspicuous consumption while veblen effects cannot ordinarily arise when preferences satisfy a single crossing property they may emerge when this property fails in that case budget brands are priced at marginal cost while luxury brands though not intrinsically superior are sold at higher prices to consumers seeking to advertise wealth luxury brands earn strictly positive profits under conditions that would with standard formulations of preferences yield marginal cost pricing the authors explore factors that induce veblen effects and they investigate policy implications copyright 1996 by american economic association

on measuring the impact of unemployment benefits on the duration of unemployment spell abstract many empirical estimates of the impact of policy changes in unemployment benefit upon the duration of unemployment spell ignore the equilibrium effect i e the demand for labor is assumed to remain unchanged we argue that this assumption is impermissible

household unemployment and the labour supply of married women a recent reform to the uk unemployment insurance ui system has reduced the duration of entitlement from 12 to six months the ui and welfare systems interact in the uk in such a way that exhaustion of ut for married individuals has potentially large disincentive effects on the labour supply of spouses a model of labour supply is estimated for married women allowing for endogenous unemployment durations of husbands and wives we distinguish between transfer programme induced incentive effects correlation between labour supply and wages within couples complementarity between the leisure times of spouses and a discouraged worker effect

financial development and economic growth views and agenda this critique argues that the preponderance of theoretical reasoning and empirical evidence suggests a positive first order relationship between financial development and economic growth the body of work would push even most skeptics toward the belief that the development of financial markets and institutions is a critical and inextricable part of the growth process and away from the view that the financial system is an inconsequential sideshow responding passively to economic growth many gaps remain however and the paper highlights areas in acute need of additional research

dollarization and the inflation threshold this paper analyzes the relationship among inflation dollarization financial intermediation and real activity empirical evidence suggests non linearity in the eects of inflation on financial intermediation and real activity i e the existence of an inflation threshold evidence also suggests that one way in which inflation aects financial intermediation in high inflation economies is through the substitution of dollars under the mattress for savings in domestic banks our model captures these empirical regularities inflation and real activity are positively related at low levels of inflation when the inflation rate exceeds certain threshold however agents substitute in their portfolios dollars a non productive asset of constant value that also provides liquidity services for deposits issued by domestic banks this substitution reduces the scale of financial intermediation and the capital investment in the economy as a consequence at high levels of inflation the levels of capital stock and output become negatively related to the inflation rate

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

endogenous unemployment insurance in a monopoly union model when job search matters abstract the aim of the paper is to derive an optimal unemployment insurance policy for a utilitarian trade union when job search matters it is shown that the well known result from the theory of insurance concerning the optimal risk sharing between risk averse agents changes essentially if the search behavior is allowed to affect the performance of the labor market we assume that labor market mismatch decreases with search effort which in turn decreases with the benefit the resulting equilibrium benefit is shown to be a decreasing function of the trade union s share of the costs of the insurance fund the model is also extended to the case where the benefit is made conditional on monitored search effort

unemployment benefit duration and incentives in britain how robust is the evidence abstract recent years have seen considerable advances in the econometric treatment of micro data in models of unemployment duration this paper examines the evidence from such models concerning the effects of unemployment benefits on incentives to work in britain widely accepted results of a small but significant benefit effect are reproduced using a sample of 1 231 unemployed men however these results are only found when benefit receipt is assumed to follow a hypothetical pattern which is shown to be unrealistic and over generous when more realistic calculations of benefits are used no benefit effect is found the paper also argues that search theory is of little help in determining the choice between competing functional forms and explanatory variables results concerning benefits are shown to be sensitive to the latter
