inflation taxation and welfare with externalities and leisure this paper examines how inflation taxation affects resource allocation and welfare in a neoclassical growth model with leisure a production externality and money in the utility function switching from consumption taxation to inflation taxation to finance government spending reduces real money balances relative to income but increases consumption labor capital and output the net welfare effect of this switch depends crucially on the strength of the externality and on the elasticity of intertemporal substitution while it is always negative without the externality it is likely to be positive with a strong externality and elastic intertemporal substitution

the inflation tax in a real business cycle model money is incorporated into a real business cycle model using a cash in advance constraint the model economy is used to analyze whether the business cycle is different in high inflation and low inflation economies and to analyze the impact of variability in the growth rate of money in addition the welfare cost of the inflation tax is measured and the steady state properties of high and low inflation economies are compared

alternative approaches to money and growth this paper reexamines the issue of money and growth in an economy with both endogenous labor supply and endogenous capital stock using three recently developed approaches the money in the utility function approach the cash in advance approach and the transactions costs approach by establishing a qualitative equivalence between alternative setups the authors find economically justifiable conditions such that all comparative statics results derived from the aforementioned approaches are identical copyright 1992 by ohio state university press

the spread of municipal reform temporal spatial and social dynamics the adoption of commission and managerial administrative structures and their subsequent abandonment by the 267 largest american cities during the period 1900 1942 is studied using event history methods full period equations show no significant direct effect of percentage catholic culture clash or population size hierarchical diffussion and only a modest impact of city age modernization a strong effect from average annual manufacturing wages is found but in a direction contrary to that posited by the class conflict hypothesis the variable affecting transition rates most strongly appears to be regional adoption percentages an indicator of neighborhood diffusion these findings suggest revisions of the conventional image of the municipal reform experience

the role of search costs in determining the relationship between inflation and profit margins previous empirical studies have found a negative relationship between inflation and industry profit margins recent theoretical findings however suggest that buyer search costs can significantly impact this relationship we use an actual measure of search cost that varies across wholesale industries to estimate the impact of these costs on the relationship between inflation and markups using firm level data from 57 industries we show that margins increase during inflation if search costs become sufficiently high our findings reconcile the theoretical and empirical literatures on this topic

the relation between price and marginal cost in u s industry a contradiction in a recent article in this journal hall 1988 examined productivity shocks at the industry level derived from constant returns to scale production functions in which firms were assumed to be competitive hall had two important conclusions first he showed that productivity shocks i e solow residuals were correlated with aggregate demand variables implying that the former are not exogenous impulses second his results implied that firms persistently charge prices above marginal costs making inappropriate the constant returns to scale competitive production function assumed in many theoretical frameworks because of the importance of hall s findings the article has led to many extensions evans 1992 confirms the empirical finding of significant correlations between productivity shocks and aggregate demand variables burnside eichenbaum and rebelo 1993 show that this correlation can be explained by introducing labor hoarding into a theoretical model with competitive firms and constant returns to scale production functions the markups above marginal cost are explained by eden and griliches 1991 and galeotti and schiantarelli 1991 by modifying the theoretical production function caballero and lyons 1992 using the hall data and methodology examine the possibility of external economies in the aggregate manufacturing production finally waldmann 199 1 argues in this journal that the

monopolistic competition increasing returns to specialization and output persistence abstract devereux et al economics letters 1993 41 57 61 showed that introducing together imperfect competition and increasing returns to specialization into real business cycle rbc type models results in making output more persistent than the underlying technology shocks we carry out a simple generalization of their model which clearly disentangles the two features and show that the added persistence is actually because of the increasing returns to specialization

production function regressions returns to scale and externalities a number of recent papers have used simple linear regressions in an attempt to identify market structure the extent of returns to scale and possible external effects in u s manufacturing industries the results obtained from these regressions have important implications for several branches of modern macroeconomics as a result the macro literature frequently cites specific numerical evidence from caballero and lyons 1992 and hall 1990 which suggests that there are quantitatively significant increasing returns to scale or external effects in u s manufacturing in contrast it is the argument of this paper that this evidence is not convincing the most robust evidence suggests that the typical u s manufacturing industry displays constant returns with no external effects on the other hand there is significant heterogeneity across industries

money output and income velocity this paper attempts to assess empirically the contribution of three structural shocks monetary institutional financial and fiscal and technological to output and velocity fluctuations in the national bank era and the post 1973 period to identify these shocks we impose only long run restrictions derived from a monetary growth model we find that higher money growth increases decreases velocity in the first second period depending crucially on the resulting changes in the transactions frequency credit enhancing financial or expansionary fiscal shocks have a permanent positive effect on velocity and a himp shaped effect on output whereas technological shocks cause velocity to decrease in the short run and output to move to a permanently higher level

markups and the number of firms in a simple model of imperfect competition abstract two counter intuitive results regarding the number of firms emerge from the existing monopolistic competition literature first the number of firms is positively related to the extent of the monopoly power second when the goods market is perfectly competitive the number of firms is reduced to zero this paper proposes a plausible way to escape from these two counter intuitive deficiencies

inflation and asset returns in a monetary economy postwar u s data are characterized by negative correlations between real equity returns and inflation and by positive correlations between real equity returns and money growth these patterns are closely matched quantitatively by an equilibrium monetary asset pricing model the model also implies negative correlations between expected asset returns and expected inflation and it predicts that the inflationasset return correlation will be more strongly negative when inflation is generated by fluctuations in real economic activity than when it is generated by monetary fluctuations the co movements of real asset returns inflation and money growth have been studied extensively over the past fifteen years table i displays some of the statistical properties of these series using quarterly u s data from 1959 to 1990 note first the significantly negative correlation between real equity returns and inflation note also the negative correlation between inflation and the ex post real return to nominally riskless bonds while this fact is not particularly surprising numerous studies conclude that the correlations between ex ante real asset returns and expected inflation are also negative 2 in contrast to these patterns the correlation between money growth and real equity returns is weakly positive in the data while the correlation between money growth and the real bond return is virtually zero initially these empirical patterns were viewed as anomalies negative correlations between inflation and ex post real stock returns contradict the traditional view that equities ought to act as an inflation hedge 3 negative correlations between expected inflation and ex ante real returns violate the

inflation and welfare in a monetary economy it is in everyone s private interest to try to get someone else to hold non interest bearing cash and reserves but someone has to hold it all so these efforts must simply cancel out all of us spend several hours per year in this effort and employ thousands of talented and highly trained people to help us these person hours are simply thrown away wasted on a task that should not have to be performed at all

local government type and municipal bond ratings what s the relationship abstractthere is an extensive literature analysing the executive branch within local u s government jurisdictions this has largely revolved around the differences between elected mayors and appointed city managers much of the academic work has considered the potential efficiency gains that may be associated with either form of government and comparative analyses between the two however the empirical literature has been divided regarding the relative efficiency of either form this article attempts to add to that literature by considering how bond markets may perceive potential efficiencies that emerge from one executive type over the other by evaluating bond ratings for a sample of large municipal governments in the united states overall the results suggest that municipalities headed by a city manager are associated with increased bond ratings and thus lower borrowing costs which may lend support that this form of administration is on some margin relatively more efficient than others these re

monopolistic competition increasing returns to scale and the importance of productivity shocks abstract the neoclassical growth model is extended to incorporate monopolistic competition and increasing returns to scale implications for the measurement of productivity change through the solow residual are studied it is found that for this extension productivity fluctuations continue to account for a substantial fraction of output volatility the model cannot account for volatility of employment

search costs sticky prices and markups this article investigates how search costs price stickiness and product durability influence the impact of inflation on firm markups we provide evidence that each of these three factors plays an independent role in influencing the responsiveness of markups to inflation although we find that the direct effect of inflation on markups is negative offsetting positive influences of inflation on markups arise in industries that produce durable experience goods with flexible prices thus our results indicate that markups of industries producing nondurable search goods with sticky prices tend to experience unambiguously negative impacts from inflation

exchange rate determination interest rates and an integrative approach to the demand for money abstract this paper presents a simple framework in which the money in the utility function miuf and the cash in advance cia approaches to the demand for money can be seen as equivalent this integrative approach to money demand is extended to a two country world and the equilibrium relationship between terms of trade exchange rates and interest rates implied by the underlying stochastic structure of the economy is discussed a theory of currency substitution is presented

employment effects of minimum and subminimum wages panel data on state minimum wage laws using panel data on state minimum wage laws and economic conditions for the years 1973 89 the authors reevaluate existing evidence on the effects of a minimum wage on employment their estimates indicate that a 10 increase in the minimum wage causes a decline of 1 2 in employment among teenagers and a decline of 1 5 2 in employment for young adults similar to the ranges suggested by earlier time series studies the authors also find evidence that youth subminimum wage provisions enacted by state legislatures moderate the disemployment effects of minimum wages on teenagers

using regional variation in wages to measure the effects of the federal minimum wage the imposition of a national minimum wage standard provides a natural experiment in which the treatment effect varies across states depending on the fraction of workers initially earning less than the new minimum the author exploits this fact to evaluate the effect of the april 1990 increase in the federal minimum wage on teenagers wages employment and school enrollment comparisons of grouped and individual state data confirm that the rise in the minimum wage increased teenagers wages there is no evidence of corresponding losses in teenage employment or changes in teenage school enrollment

money and endogenous growth the ramsey romer model of endogenous growth is extended to allow for holdings of real money balances and government debt as well as capital and for non interconnected generations of households tax financed increases in government consumption and debt depress growth prospects and boost inflation as long as a positive birth rate ensures that future taxes are shouldered by future yet unborn generations debt financed increases in government consumption depress growth and boost inflation even more money financed increases in government consumption depress growth less but increase inflation by more giving subsidies through an increase in monetary growth is non neutral since this increases real growth and thus inflation increases by a lesser amount than monetary growth bond financed increases in monetary growth lead to a larger increase in real growth and a smaller increase in inflation if there are cost adjustment for investment cuts in monetary growth and increases in government debt and government consumption induce an increase in the real interest rate copyright 1994 by ohio state university press

endogenous growth and real effects of monetary policy r d and physical capital complementarities we study the real long run effects of the structural stance of monetary policy and of inflation in the context of a monetary growth model where r d is complemented with physical capital accumulation we look into the effects on a set of real macroeconomic variables that have been of interest to policymakers the economic growth rate real interest rate physical investment rate capital to labor ratio r d intensity and velocity of money these variables have been previously analyzed from the perspective of different separated strands of the theoretical and empirical literature additionally we analyze the long run relationship between inflation and both the effectiveness of real industrial policy shocks and the market structure assessed namely by average firm size we present novel cross country evidence on the empirical relationship between the latter and long run inflation

money and the welfare cost of inflation in an r d growth model this study analyzes the effects of inflation on r d and innovation driven growth in the theoretical section we incorporate money demand into a quality ladder model with elastic labor supply and derive the following results if the elasticity of substitution between consumption and the real money balance is less greater than unity then r d and output growth are decreasing increasing in inflation if either labor supply is inelastic or the elasticity of substitution between consumption and the real money balance is unity then social welfare monotonically increases as the nominal interest rate approaches zero i e the friedman rule quantitatively decreasing inflation in the us to achieve price stability improves welfare equivalent to a permanent increase in consumption of at least 0 5 in the empirical section we use cross country data to establish a negative and statistically significant relationship between inflation and r d

distributive politics ward representation and the spread of zoning this analysis examines two alternative explanations for the adoption of comprehensive zoning ordinances in the years immediately following its initial adoption in new york city the market failure explanation predicts zoning adoption in cities where externality problems represented by heavy incidence of manufacturing exist the distributive policymaking model treats zoning as a form of regulation that is most likely to be found in cities where local legislators are elected from geographically concentrated constituencies e g wards and therefore try to target policy benefits to their own constituencies while spreading the policy costs over all constituencies some support is found for each model especially striking is the interactive effect of ward representation and of economic interest i e levels of home ownership

external effects in u s procyclical productivity abstract in this paper we highlight a new dimension of the aggregate procyclical productivity phenomenon we show that estimates of the degree of returns to scale are larger for manufacturing as a whole than for two digit industries since this difference must be due to factors that are only internalized at the most aggregate level we term it an external effect this result rules out explanations based on own input variation such as true increasing returns and unmeasured factor utilization tied to own activity as the sole explanations for aggregate procyclical productivity we explore several potential explanations of this external effect

returns to scale in canadian manufacturing an interprovincial comparison this paper measures the degree of returns to scale at the two digit standard industrial classification sic in canadian manufacturing employing both gross output and value added data using a model developed by r j caballero and r k lyons the study distinguishes between internal and external returns to scale the caballero and lyons model is extended by disaggregation to the provincial level in order to measure the returns to scale of geographic provincial concentration the empirical results suggest that in canada there are increasing returns that are primarily national rather than internal to the province or the industry

determinants of patent rights a cross national study abstract this paper presents an index of patent rights for 110 countries for the period 1960 1990 the index is used to examine what factors or characteristics of economies determine how strongly patent rights will be protected the evidence does indicate that more developed economies tend to provide stronger protection but the underlying factors which influence patent protection levels are the country s level of research and development r d activity market environment and international integration which are correlated with its level of development the results qualify however that r d activity influences patent protection levels after a nation s research sector reaches a critical size an implication of this is that to raise patent protection levels in weakly protecting countries it is important to foster a significant research base in those countries and thereby create incentives for protecting patent rights

minimum wage policy and employment effects evidence from brazil the international literature on minimum wages greatly lacks empirical evidence for latin america in brazil not only are minimum wage increases large and frequent but they also have been used as both a social policy and an anti inflationary policy this paper estimates the effects of the minimum wage on wages and employment using panel data techniques and brazilian monthly household data from 1982 to 2000 a number of conceptual and identification questions are discussed for example the paper summarizes various strategies on how best to measure the effect of a constant national minimum wage presenting a menu of minimum wage variables that are then used to estimate wage and employment effects the paper also uses an employment decomposition that separately estimates the effect of the minimum wage on hours per worker and on the number of jobs robust results indicate that an increase in the minimum wage strongly compresses the wages distribution with small adverse effects on employment

the optimal inflation rate under schumpeterian growth abstract to analyze the relationship between inflation and economic growth we construct an endogenous growth model with creative destruction incorporating sticky prices due to menu costs price changes reduce the reward for innovation and thus lower the frequency of creative destruction central banks can maximize the growth rate by setting their inflation target at the negative of a fundamental growth rate while the optimal inflation rate may be greater than the growth maximizing inflation rate our calibrated model shows that the optimal inflation rate is close to the growth maximizing inflation rate and that a deviation from the optimal level has sizable impacts

diffusion of regulatory impact analysis among oecd and eu member states with the exception of few comparative case studies the literature on regulatory reform and regulatory impact analysis ria tends to focus on internal political actors activities and processes furthermore empirical analyses of new public management have overlooked the dynamics of communications among networks of administrative reformers this article fills these gaps presenting results of an event history analysis on the diffusion of ria it probes rationales for the origin of ria and administrative capacity explanations in combination with variables referring to international and transnational communication channels of administrative reforms a hypothesis based on legal origin is also tested the findings show that the decision to adopt ria rests on transnational networks as well as administrative variables such as government expenditure and legal origin

increasing returns and externalities in uk manufacturing myth or reality i apply the method of caballero and lyons to industry level data for uk manufacturing i find evidence for a positive external effect arising from the expansion of manufacturing as a whole but expansion at the sectoral level was found not to generate external effects nor was any evidence found for increasing returns which are internal to the industry here returns appear to be constant i argue that external effects at the level of aggregate manufacturing cannot be explained away as due to measurement error or cyclical effects however alternative explanations such as economy wide shocks cannot be totally excluded

indivisible labor and the business cycle abstract a growth model with shocks to technology is studied labor is indivisible so all variability in hours worked is due to fluctuations in the number employed we find that unlike previous equilibrium models of the business cycle this economy displays large fluctuations in hours worked and relatively small fluctuations in productivity this finding is independent of individuals willingness to substitute leisure across time this and other findings are the result of studying and comparing summary statistics describing this economy an economy with divisible labor and post war u s time series

wage offers and full time and part time employment by british women strong evidence in support of the hypothesis that women receive lower wage offers in part time jobs than in full time jobs is provided by estimation of wage offer functions for british women which control for self selection into these two types of jobs analysis of married women s employment decisions indicates that the difference in a woman s expected wage offers between full time and part time employment is an important determinant of whether she works full time while husband s income mainly affects the decision of whether to work in addition it appears that women who work despite having observed characteristics that discourage employment are much more likely to work part time

money and exchange rates in the grossman weiss rotemberg model abstract we analyze the impact of monetary policy on inflation interest rates and exchange rates in a model with segmented asset markets developed by grossman and weiss 1983 and rotemberg 1984 1985 we find parameters for which real and nominal exchange rates in this model are 1 much more volatile than interest rates inflation rates and money growth rates 2 highly correlated with each other and 3 highly persistent while this model fails to match the data in other important respects it illustrates a potentially useful approach to modelling exchange rate behavior

the optimal inflation path in a sidrauski type model with uncertainty abstract in this paper it is shown that in a sidrauski type model with uncertainty the chicago rule remains valid as a prescription for the average rate of inflation although there is a systematic difference between the perfect foresight and the uncertainty case quantitatively however the difference turns out to be very small the paper shows how to calculate the optimal monetary policy as a function of the state variables using the method of parameterized expectations in terms of expected utility the optimal policy is as good as the simple policy that reduces the money supply at the rate of time preference

dynamic behavior of capital accumulation in a cash in advance model abstract this paper analyzes the dynamic behavior of capital accumulation in stockman s cash in advance model if the cash in advance constraint applies only to consumption then money is superneutral along the transition path as well as in the long run alternatively if the cash in advance constraint applies to gross investment as well as consumption then a permanent increase in the rate of monetary growth reduces the steady state capital stock the effect on the speed of adjustment depends on the sign of a certain simple function of the parameters of preferences and technology

on the welfare cost of inflation and the recent behavior of money demand post 1980 u s data trace out a stable long run money demand relationship of cagan s semi log form between the m1 income ratio and the nominal interest rate with an interest semi elasticity of 1 79 integrating under this money demand curve yields estimates of the welfare cost of modest departures from friedman s zero nominal interest rate rule for the optimum quantity of money that are quite small the results suggest that the federal reserve s current policy which generates low but still positive rates of inflation provides an adequate approximation in welfare terms to the alternative of moving all the way to the friedman rule jel e31 e41 e52

money and asset prices in a cash in advance economy an asset pricing model with money introduced via a cash in advance constraint is presented the monetary velocity is variable hence money demand does not obey the trivial quantity equation the effects of disturbances in output and money growth on real balances the price level and interest rates are examined monetary policy has effects on real asset prices the fisher relation and the premium on nominal bonds are discussed the precise role of the timing of information and transactions for properties of price levels and interest rates are clarified

international patent protection 1960 2005 abstract this note provides an update to the index of patent protection published in this journal in 1997 the original paper presented the index for 1960 1990 for 110 countries the index has now been updated to 2005 and extended to 122 countries the adoption of stronger patent laws and the composition of patent rights vary across countries by level of economic development

a selectivity model of employer size wage differentials this article investigates wage differentials for employees of different size firms utilizing an econometric methodology that allows the size of employer to be treated as endogenous in the context of discrete ordered employer size data as a result we are able to estimate i employer size wage gaps which are corrected for selectivity bias and ii the magnitude and direction of the selection bias decompositions of the resulting wage differentials are computed with comparisons of the conditional on sorting across employer size and unconditional wage gaps

anticipated inflation in a monetary economy with endogenous growth this paper makes a new attempt to investigate the role of anticipatedmonetary growth in economic growth combining the barro 1990 rebelo 1991 type endogenous growth model with sidrauski s 1967 framework we show that the pre announcement of money supply behaviour may have significant effects on the rate of growth during the transition process the key factor indetermining adjustment patterns of the economy to anticipated monetary changes is the degree of relative risk aversion however changes in the rate of monetary growth do not affect the rate of long run growth regardless of the degree of relative risk aversion

endogenous markups intensity of competition and persistence of business cycles in order to study the propagation mechanism of business cycles in particular to investigate how the intensity of competition affects market structure and output persistence over business cycles this paper presents a real business cycle model with imperfect competition and increasing returns to scale this analysis considers the markups of price over cost to be endogenous with endogenous markups two standard forms of oligopolistic competition bertrand and cournot are considered results show that 1 the propagation mechanism in the sense of output persistence is greater under cournot 2 the propagation mechanism is unequivocally greater with imperfect competition regardless of whether markups are endogenous or not and 3 under imperfect competition the propagation mechanism is greater with endogenous markups than with exogenous markups overall these results suggest that more intense competition produces lower persistence in output growth and thus a weaker propagation mechanism in a calibration exercise these differences were also found to be quantitatively important

inflation targeting a new framework for monetary policy he world s central bankers and their staffs meet regularly in venues from basle to washington to share ideas and discuss common problems perhaps these frequent meetings help explain why changes in the tactics and strategy of monetary policymaking such as the adoption of money growth targets in the 1970s the intensification of efforts to reduce inflation in the 1980s and the recent push for increased institutional independence for central banks tend to occur in many countries more or less simultaneously whatever their source major changes in the theory and practice of central banking are of great importance for both individual countries and the international economy in this article we discuss a new strategy for monetary policy known as inflation targeting which has sparked much interest and debate among central bankers and monetary economists in recent years this approach is characterized as the name suggests by the announcement of official target ranges for the inflation rate at one or more horizons and by explicit acknowledgment that low and stable inflation is the overriding goal of monetary policy other important features of inflation targeting include increased communication with the public about the plans and objectives of the monetary policymakers and in many cases increased accountability of the central bank

money and interest in a cash in advance economy the authors analyze an aggregative general equilibrium model in which the use of money is motivated by a cash in advance constraint applied to purchases of a subset of consumption goods the system is subject to both real and monetary shocks which are economy wide and observed by all they develop methods for verifying the existence of characterizing and explicitly calculating equilibria copyright 1987 by the econometric society

contrasting models of the effect of inflation on growth the paper formulates a nesting model for studying the theoretical literature on inflation and endogenous growth it analyses different classes of endogenous growth models with different usage of physical and human capital with different exchange technologies first the paper shows that a broad array of models can all generate significant negative effects of inflation on growth second it shows that these models can be differentiated primarily by the fact whether there is a tobin type effect of inflation and also whether the inflation growth effect becomes weaker as the inflation rate rises a non linearity or stays essentially constant over the range of inflation rates the paper compares these features of the models to empirical evidence as a way to summarize the efficacy of the models

anticipated inflation and the capital stock in a cash in advance economy abstract an economy is constructed in which the steady state capital stock is inversely related to the rate of inflation as a result that is directly opposite the usual conclusion

the effects of inflation on the number of firms and firm size a typical money and growth model generally incorporates an implicit assumption that the number of firms or the set of goods available is fixed this paper attempts to investigate the implications of relaxing this assumption in a monopolistically competitive model with endogenous markup it is found that among other effects inflation reduces the number of firms and each firm s size moreover due to this new channel inflation induces secondary effects one direct implication is that the welfare costs of inflation in our framework are substantially higher than those documented in existing models with standard features our findings suggest that it is the lessening of competition that appears to be the primary driving force

inflation investment and growth a money and banking approach output growth investment and the real interest rate in long run evidence tend to be negatively affected by inflation theoretically inflation acts as a human capital tax that decreases output growth and the real interest rate but increases the investment rate opposing evidence this paper resolves this puzzle by requiring exchange for investment as well as consumption inflation then decreases the investment rate and still decreases both output growth and real interest up to some moderately high rate of inflation above which increasingly low investment finally causes capital to fall relative to labour and the real interest rate to rise

oligopsony and monopsonistic competition in labor markets we argue that models of oligopsony or monopsonistic competition provide insights and explanation for many empirical phenomena in labor markets using a simple model with job differentiation and preference heterogeneity we illustrate how such models can be employed to explain the existence of wage dispersion the persistence of labor market discrimination market failures in the provision of training and the anomalous employment effects of minimum wages

money and growth revisited abstract conventional wisdom is that if public policy can affect the growth rate of the economy the welfare implications of alternative policies will be large in this paper a stochastic dynamic general equilibrium model with endogenous growth and money is examined in this setting inflation lowers growth through its effect on the return to work however the welfare costs of higher inflation are modest the endogenous labor supply is important in producing this result

the mechanisms of policy diffusion local policy adoptions provide an excellent opportunity to test among potential mechanisms of policy diffusion by examining three types of antismoking policy choices by the 675 largest u s cities between 1975 and 2000 we uncover robust patterns of policy diffusion yielding three key findings first we distinguish among and find evidence for four mechanisms of policy diffusion learning from earlier adopters economic competition among proximate cities imitation of larger cities and coercion by state governments second we find a temporal component to these effects with imitation being a more short lived diffusion process than the others third we show that these mechanisms are conditional with larger cities being better able to learn from others less fearful of economic spillovers and less likely to rely on imitation

demographic factors affecting constitutional decisions the case of municipal charters after decades of studying municipal charters largely by looking for patterns in the data we have a good basis for proceeding more formally with testable theories the political significance of demographic change becomes apparent by looking at its impact on political conflict in combination with the biases in social choice rules the theory of civil rights provides a framework for doing this it suggests identifying 1 the distribution of civil rights conveyed to citizens by alternative charters and 2 the bases for political conflict such as different demands for services and the unequal command of economic resources to satisfy them charters then become political tools simple statistical tests fail to refute this

currency substitution under nonexpected utility some empirical evidence this paper derives and tests the restrictions implied by an optimizing model of currency substitution under nonexpected utility using quarterly data for israel from 1978 to 1988 we find that the elasticity of intertemporal substitution is less than one the elasticity of currency substitution is greater than one relative risk aversion is about seven and the elasticity of currency substitution is greater than the intratemporal elasticity of substitution between consumption and liquidity services in most cases the evidence supports the hypothesis of nonexpected utility as well as the inclusion of liquidity services in the representative agent s objective function the methodology of this paper can be applied to other interesting cases of currency substitution copyright 1993 by ohio state university press

social network effects on the extent of innovation diffusion a computer simulation of innovation diffusion no longer focus exclusively on explaining the rate at which innovations diffuse or the sequence in which they are adopted they also focus on explaining why certain innovations diffuse extensively be coming de facto standards whereas others do so partially or not at all many of these theories specify a bandwagon process a positive feedback loop in which increases in the number of adopters create stronger bandwagon pressures and stronger bandwagon pressures in turn cause increases in the number of adopters factors affecting if and how many times this feedback loop cycles explain if and how many potential adopters jump on a bandwagon we argue that one important factor has not yet been incorporated into theories explaining bandwagons extent the structure of social net works through which potential adopters of innovations find out information about these innovations which can cause them to adopt these innovations we advance a theory of how the structure of social networks affects bandwagons extent we propose that both the number of network links as well as small seemingly insignificant idiosyncracies of their structures can have very large effects on the extent of an innovation s diffusion among members of a social network

the behavior of money velocity in high and low inflation countries this paper presents a general equilibrium model of money demand where the velocity of money changes in response to endogenous fluctuations in the interest rate the parameter space can be divided into two subsets one where velocity is constant as in standard cash in advance models and another one where velocity fluctuates as in baumol 1952 the model provides an explanation of why for a sample of 79 countries the correlation between the velocity of money and the inflation rate appears to be low unlike common wisdom would suggest the reason is the diverse transaction technologies available in different economies

inflation and balanced path growth with alternative payment mechanisms the paper shows that contrary to conventional wisdom an endogenous growth economy with human capital and alternative payment mechanisms can robustly explain major facets of the long run inflation experience a negative inflation growth relation is explained including a striking nonlinearity found re peatedly in empirical studies a set of tobin 1965 effects are also explained and further linked in magnitude to the growth effects through the interest elasticity of money demand undis closed previously this link helps fill out the intuition of how the inflation experience can be plausibly explained in a robust fashion with a model extended to include credit as a payment mechanism

cluster sample methods in applied econometrics inference methods that recognize the clustering of individual observations have been available for more than 25 years brent moulton 1990 caught the attention of economists when he demonstrated the serious biases that can result in estimating the effects of aggregate explanatory variables on individual specific response variables the source of the downward bias in the usual ordinary least squares ols standard errors is the presence of an unobserved state level effect in the error term more recently john pepper 2002 showed how accounting for multi level clustering can have dramatic effects on t statistics while adjusting for clustering is much more common than it was 10 years ago inference methods robust to cluster correlation are not used routinely across all relevant settings in this paper i provide an overview of applications of cluster sample methods both to cluster samples and to panel data sets

privatisation of waste collection services in response to fiscal stress in times of crisis according to the conventional theoretical framework fiscal stress is an explanatory factor of privatisation since the latter can provide economies of scale and cost savings as indicated by the theory of public choice however urban planning theories suggest that public choice does not take into account the collective needs of those receiving public services the present study aims to clarify two major issues firstly in the presence of fiscal stress do public managers really privatise and secondly does privatisation harm the public interest to investigate these questions we constructed and analysed a discrete time survival model which was applied to the period 2000 2010 to reflect the effects of the current global financial crisis on the fiscal stress privatisation relationship with respect to urban waste collection services the results obtained indicate that when certain aspects of financial condition worsen the likelihood of public services being privatised increases this was the case dur

the consequences of increased enforcement of legal minimum wages in a developing country an evaluation of the impact of the campana nacional de salarios minimos in costa rica in august 2010 the costa rican government implemented a comprehensive program to increase compliance with legal minimum wages the campana nacional de salarios minimos national campaign for minimum wages to evaluate the impact of the campaign the authors use a regression discontinuity rd approach which compares what happened to workers who before the campaign had been earning below the minimum wage to those who before the campaign had been earning above the minimum wage they analyze a panel data set with information on workers from before the campaign began july 2010 and after the campaign had been in operation for some time july 2011 the evidence supports the conclusion that the campaign led to an increase in compliance with minimum wage laws in costa rica the mean earnings of those being paid less than the minimum wage in 2010 increased by approximately 10 more than the earnings of those being paid more than the minimum wage the campaign led to the largest increases in the wages of wome

the welfare cost of inflation in general equilibrium abstract this paper presents a general equilibrium monetary model in which inflation distorts a variety of marginal decisions although individually none of the distortions is very large they combine to yield substantial welfare cost estimates a sustained 4 percent inflation like that experienced in the us since 1983 costs the economy the equivalent of 0 41 percent of output per year when currency is identified as the relevant definition of money and over 1 percent of output per year when m1 is defined as money the results illustrate how the traditional partial equilibrium approach can seriously underestimate the true cost of inflation

inflation and welfare in the steady state this is a paper on expected inflation and welfare in steady state equilibrium the demand for money is an inventory demand with an endogenous payment period the clower constraint is not imposed higher inflation reduces welfare by reducing consumption as people devote more of their real income to maintaining lower average money holdings high inflation does not necessarily promote an increase in the capital stock the mundell tobin effect is absent the policy conclusion is standard deflate at the rate of time preference because capital is held socially optimal consumption falls short of its golden rule level if inside money is allowed it drives out fiat money and welfare is again at a maximum

sovereignty relinquished explaining commitment to the international human rights covenants 1966 1999 this article examines whether the content of the international human rights covenants and the costs associated with their ratification influence the decision of countries to join the author evaluates three theoretical perspectives rationalism world polity institutionalism and the clash of civilizations with data for more than 130 countries between 1966 and 1999 rationalists contend that treaty ratification is tightly coupled with internal sovereignty arrangements human rights practices and ideological commitments all of which become more important as treaty enforcement strengthens world polity institutionalists expect ratification to be loosely coupled with a country s conduct or its political ideological or cultural commitments although this gap narrows as compliance is more effectively enforced a civilizations approach predicts tight coupling between ratification and cultural values regardless of the mechanisms in place for enforcing compliance results lend partial support to rationalism a

competing for global capital or local voters the politics of business location incentives the competition for global capital has led to interjurisdictional competition between countries states and cities as to who can offer the most attractive incentives to firms in this study we examine the domestic politics of this competition by focusing on incentive use in the united states from 1999 to 2012 we define incentives as the targeted tax deductions or exemptions that are used to lure businesses into a locality drawing on data from municipal incentive programs we examine how electoral competition shapes the use and oversight of targeted incentives we find evidence that cities with elected mayors provide larger incentives than non elected city managers by taking advantage of exogeneity in the assignment of city government institutions and a database of over 2000 investment incentives from 2010 to 2012 we also find that elected mayors enjoy more lax oversight of incentive projects than their appointed counterparts our results have important implications for the study of interjurisdictional competition and the role of electoral institutions in shaping economic policy

hierarchical accountability in government abstract this paper studies a setting where a relatively uninformed voter holds a policymaker accountable through an informed intermediary in equilibrium the voter uses the intermediary to insulate the policymaker from pandering incentives when the voter s policy expertise is low or the policymaker s congruence is high the voter can thus enjoy the benefits of bureaucratic expertise without forfeiting electoral responsiveness we examine the model s predictions using u s city level data and find that hierarchically accountable managers reduce popular city employment and adjust it more flexibly than electorally accountable mayors the estimated incentive effects are smaller in cities with high voter expertise and larger during election years and are robust to instrumentation by precipitation shocks that influenced early 20th century manager government adoptions for reasons obsolete today

does the minimum wage have a higher impact on the informal than on the formal labour market evidence from quasi experiments this article investigates a puzzle in the literature on labour markets in developing countries labour legislations not only have an impact on the formal labour market but also an impact on the informal sector it has even been argued that the impact on the informal sector in the case of the minimum wage is stronger than on the formal sector using quasi experiments of minimum wage changes and thereby exploiting geographical variation of the minimum wage bite i find evidence for this hypothesis informal workers workers without social security contribution experienced significant wage increases when the minimum wage was raised while formal workers did not this result highlights that noncompliance with one labour legislation the social security contribution does not necessarily imply noncompliance to other labour laws such as the minimum wage

the heckman correction for sample selection and its critique this paper gives a short overview of monte carlo studies on the usefulness of heckman s 1976 1979 two step estimator for estimating selection models such models occur frequently in empirical work especially in microeconometrics when estimating wage equations or consumer expenditures it is shown that exploratory work to check for collinearity problems is strongly recommended before deciding on which estimator to apply in the absence of collinearity problems the full information maximum likelihood estimator is preferable to the limited information two step method of heckman although the latter also gives reasonable results if however collinearity problems prevail subsample ols or the two part model is the most robust amongst the simple to calculate estimators

a simple general equilibrium version of the baumol tobin model this paper presents a simple general equilibrium model that includes optimizing choices of the frequency of trips to the bank the model is used to analyze the effect of inflation on the capital stock the interest elasticity of money demand the optimum quantity of money and the welfare costs of inflationary finance

evidence on the impact of minimum wage laws in an informal sector domestic workers in south africa what happens when a previously uncovered labor market is regulated we exploit the introduction of a minimum wage in south africa and variation in the intensity of this law to identify increases in wages for domestic workers and no statistically significant effects on employment on the intensive or extensive margins these large partial responses to the law are somewhat surprising given the lack of monitoring and enforcement in this informal sector we interpret these changes as evidence that strong external sanctions are not necessary for new labor legislation to have a significant impact on informal sectors of developing countries at least in the short run

two illustrations of the quantity theory of money of two central implications of the quantity theory of money that a given change in the rate of change in the quantity of money induces i an equal change in the rate of price inflation and ii an equal change in nominal rates of interest the illustrations were obtained by comparing moving averages of the three variables in question using quarterly u s time series for the period 1953 77 readers may find the results of interest as additional confirmation of the quantity theory as an example of one way in which the quantity theoretic relationships can be uncovered via atheoretical methods from time series which are subject to a variety of other forces or as a measure of the extent to which the inflation and interest rate experience of the postwar period can be understood in terms of purely classical monetary forces the theoretical background of the study is reviewed very briefly as it is familiar material in the next section the data processing methods are described and rationalized in section ii the illustrations

endogenous growth and the welfare costs of inflation a reconsideration abstract many economists share the view that the welfare costs of moderate rates of money growth cum inflation are generally modest or small this paper investigates the sensitivity of this result to alternative model specifications and behavioral assumptions we first construct a monetary endogenous growth model with romer s 1986 style of capital externality and find that the real growth rate effect is substantially large thus lending to much higher welfare costs than those in existing studies to investigate the robustness of the result we then conduct a series of experiments by exploring the romer model with an alternative specification of money demand and a class of other endogenous growth models it is demonstrated quite consistently that our finding is confirmed in these models
