fiscal federalism in the uk be known as a result of its association with the analysis of fiscal relations between central and local state governments in federal states such as australia canada and the u s as an expositional device i will focus on the issue of whether it would be possible to introduce a decentralised system of local and regional finance which embodies the ideas of fiscal federalism as they have been developed in such federal countries the history of constitutional development in the united kingdom suggests that the prospects for such a radical reform are slight however some form of fiscal federalism is the logical consequence of the arguments for scottish and welsh devolution perhaps accompanied by regional devolution within england and of the case for greater local government autonomy so eloquently argued in the report of the layfield committee 1976 an analysis of the feasibility should thus provide useful insights concerning the consequences and success of less drastic moves in the direction of fiscal decentralisation much of the literature on fiscal federalism is concerned with issues related to what one might term the fiscal constitution i e the allocation of responsibility for public expenditure and taxation between national and sub national units of government which may be states cantons municipalities and a variety of other local government units since the literature can be applied equally to regional government units i e states provinces cantons lander and to local in the conventional sense government units i e counties municipalities communes districts 1 shall use the term local government to refer inclusively to all sub national units of government the

intertemporal substitution and durable goods long run data abstract in this paper we use long run annual data to estimate the intertemporal elasticity of substitution while accounting for the intra temporal substitution between nondurable consumption goods and durable consumption goods we apply a two step procedure that combines a cointegration approach to preference parameter estimation with generalized method of moments

agent compensation and the limits of bonding agents in positions of trust may engage in malfeasance which is difficult to detect this paper develops a model in which employers seek to control malfeasance by paying wages contingent on imperfect monitoring and agents may be required to pay entry fees or post bonds we conclude that entry fees which exceed agents assets are ineffective in controlling malfeasance as a result conditions exist in which it is optimal to pay agents more than their opportunity cost such conditions lead to an excess supply of applicants and allow employers to engage in discrimination at zero cost to themselves

nash equilibria in models of fiscal competition abstract this paper analyzes nash equilibria in a simple model of an economy with jurisdictions engaging in fiscal competition small number nash equilibria in which tax rates are the strategic variables are shown not to coincide with nash equilibria in which public expenditure levels are the strategic variables

new keynesian models durable goods and collateral constraints abstract econometric evidence suggests that in response to monetary policy shocks durable and non durable spending co move positively and durable spending exhibits a much larger sensitivity to the shocks a standard two sector new keynesian model with perfect financial markets is at odds with these facts the introduction of a borrowing constraint where durables play the role of collateral assets helps in reconciling the model with the empirical evidence

the implications of competition among jurisdictions does tiebout need politics the paper investigates whether compensation among local jurisdiction is by itself sufficient to ensure efficient provision of local public goods jurisdictions have fixed boundaries and each has an entrenched government with the power to tax and supply the public good residents can move costlessly among jurisdictions it is shown that competition among numerous jurisdictions is not sificient to guarantee public sector efficiency though residents can vote with their feet land is immobile hence governments can unsurp some land rents for their own ends increasing the number of jurisdictions limits but cannot completely eliminate the ability to exercise discretionary governmental power

tax competition nash equilibria and residential mobility abstract wildasin journal of public economics 35 241 249 1988 examines and compares the equilibrium policies of governments when they compete in the tax rate and when they compete in the government service he finds that the two equilibrium outcomes differ with governments having greater government expenditures when they compete in taxes wildasin however assumes that residents are immobile here i show that while these two equilibria will still generally differ when residents are mobile wildasin s conclusion that competition in the tax rate results in higher government service levels does not hold when the demand for housing is elastic and government policies are chosen to maximize land rent when governments maximize the utility of landowning residents the results are reversed competition in the tax rate results in higher government service levels when the demand for housing is elastic and lower service levels when the demand is inelastic

demand disturbances and aggregate fluctuations the implications of near rationality the paper investigates some properties of near rational models of the cycle examining two types of framework in the first an otherwise classical competitive economy is shown to respond to demand disturbances when some firms follow a near rational hiring policy in the second model a dynamic setting is addressed and a criterion termed stochastic near rationality is employed simulation results are consistent with recent empirical findings and suggest that further quantitative evaluation is merited copyright 1987 by royal economic society

sectoral comovement monetary policy shocks and input output structure the comovement of output across the sector producing nondurables i e nondurable goods and services and the sector producing durables is well established in the monetary business cycle literature however standard sticky price models that incorporate sectoral heterogeneity in price stickiness i e sticky nondurables prices and flexible durables prices cannot generate this feature we argue that an input output i o structure provides a solution to this problem here we develop a two sector model with an i o structure which is calibrated to the u s economy in the model each sector s output affects those of the others by acting as an intermediate input this connection between the sectors provides a channel through which sectoral comovement is induced

real wages over the business cycle evidence from panel data one topic on which keynes did not disagree with classical economists was the cyclical behavior of real wages keynes 1936 as well as various classical writers predicted that real wages should move countercyclically quoting the general theory p 17 in general an increase in employment can only occur through the accompaniment of a decline in real wages thus i am not disputing this vital fact which the classical economists have rightly asserted as indefeasible this prediction is based on the premise of competition and a given short run capital stock increases in employment then correspond to more intensive use of capital and through diminishing product lower real wages for this reason evidence by dunlop 1938 and tarshis 1939 that real wages move procyclically was viewed as paradoxical both dunlop and tarshis based their findings on an observed positive correlation between real and money wages which given the procyclical movement of money wages implies a positive correlation between

optimal monetary policy with durable consumption goods abstract we document that the durable goods sector is much more interest sensitive than the nondurables sector and then investigate the implications of these sectoral differences for monetary policy we formulate a two sector general equilibrium model that is calibrated both to match the sectoral responses to a monetary shock derived from our empirical var and to imply an empirically realistic degree of sectoral output volatility and comovement while the social welfare function involves sector specific output gaps and inflation rates the performance of the optimal policy rule can be closely approximated by a simple rule that targets a weighted average of aggregate wage and price inflation in contrast a rule that stabilizes a more narrow measure of final goods price inflation performs poorly in terms of social welfare

quantities qualities and multiple public services in the tiebout model abstract this paper introduces a new more realistic characterization of local public services this characterization fits education parks and streets none of which are a pure samuelsonian good it is shown that tiebout s hypothesis holds for this new type of services provided correct user charges are adopted introducing several local services considerably affects the results the paper emphasizes the difference in tastes with regard to quality as opposed to quantity earlier literature is shown to apply to the role of quality and ignores the role of quantity the effect of the latter makes mixed communities more efficient than segregated ones it is shown that efficient allocation with mixed communities is an equilibrium in a costless mobility tiebout type setting

unemployment long term employment relations and productivity growth using an effort regulation type of efficiency wage model it is demonstrated that a firm may respond to slackening labor markets by acting to increase the intensity with which workers work the magnitude of this work intensity effect depends on the structure of employment relations where long term employment relations are prevalent the effect of labor market slack on work intensity may be diminished these propositions are tested empirically by estimating the effects unemployment and long term employment have on productivity growth in two digit manufacturing industries copyright 1987 by mit press

behavioural heterogeneity under evolutionary pressure macroeconomic implications of costly optimisation a model is developed in which a continuum of agents makes interdependent output decisions in a stochastic environment characterised by strategic complementarity two groups are distinguished naive agents follow a costless adaptive expectations rule while sophisticated agents incur an optimisation cost to achieve self fulfilling expectations the paper studies the dynamics generated as the population composition evolves under pressure of differential payoffs sophisticated agents are favoured if optimisation is cheap or the stochastic environment highly variable but naive agents generally persist a higher long run share of sophisticated agents is associated with greater output variability and low output persistence several attempts have been made in the recent macroeconomic literature to explore the implications of allowing for behavioural heterogeneity among economic agents typically the standard postulates of unbounded rationality are held to apply only to a subset of the population while the remainder is assumed to behave in accordance with some alternative specification the nature of which depends on the situation being analysed akerlof and yellen

competitive equilibrium and the core in club economies with anonymous crowding in club economies with anonymous crowding competitive equilibrium states of the economy are efficient and coincide with the core when there is only one private good anonymous admission prices permit consumers with different tastes to share facilities consumers might do so when their demands for facility size and crowding coincide in which case sharing is efficient thus similarity of demands is the relevant consideration for efficiently grouping consumers with different tastes

reexamining the cyclical behavior of the relative price of investment we document the cyclical behavior of the relative price of investment goods for the us economy over the last fifty years there is no robust evidence that this relative price is countercyclical for the post 1983 period it is predominantly procyclical

community composition and the provision of local public goods abstract there is considerable evidence suggesting that the composition of the community that is the characteristics of the residents themselves plays a central role in determining levels of important public outputs such as education and public safety this paper explores the normative implications of this evidence we show that optimal community composition involves a trade off between the gains from homogeneity in demands among residents and the gains from heterogeneity in the production of those goods the analysis establishes a role for equalizing intergovernmental grants on efficiency grounds such grants can provide the needed incentives for sustaining heterogeneous communities

consumer durables and the real interest rate one important channel through which real interest rates affect aggregate demand is consumer expenditure on durable goods this paper examines empirically the link between interest rates and consumer durables solving for the decision rule relating income and interest rates to consumer demand is an intractable task this paper avoids this problem by examining the first order conditions necessary for maximization by the representative consumer structural parameters of there presentative utility function are thus recovered the estimated model suggests that expenditure on consumer durables is far more sensitive to changes in the interest rate than is expenditure on nondurables and services this abstract was borrowed from another version of this item

capital credit constraints and the comovement between consumer durables and nondurables evidence indicates that consumer durables are more flexibly priced than nondurable goods and services in otherwise standard two sector neoclassical sticky price models with flexible durable prices following monetary tightening nondurables decrease but consumer durables increase friction in lending between households can resolve the comovement problem if durable prices are sticky however if durable prices are flexible friction in lending fails to generate joint decline this paper resolves the co movement problem by adding capital into a model with flexible durable prices and friction in lending when capital is needed in production monetary tightening reduces the relative price of durables which induces investment and decreases firms real profits in the short run due to fewer profits remitted from firms savers have a lower disposable income and cannot increase expenditures on consumer durables as much as otherwise as a consequence aggregate consumer durables decrease and there is a joint decline of nondurables and consumer durables

work norms and involuntary unemployment consider the organizational environment of labor management wherein the firm can measure the average performance i e group work norm of its employees but has difficulty in observing the individual worker s performance within the group accordingly the worker s remuneration is based on the observed group norm because of the way in which workers interact among themselves in setting work norms there results an undersupply of effort from a given workforce size furthermore the group work norm is shown to be negatively correlated with the size of the workforce consequently short run unemployment can arise with involuntary features the paper also explores the effectiveness of alternative remuneration schemes in mitigating the inefficiency associated with the group work norm setting

sectoral shifts and cyclical unemployment a substantial fraction of cyclical unemployment is better characterized as fluctuations of the frictional or natural rate than as deviations from some relatively stable natural rate shifts of employment demand between sectors of the economy necessitate continuous labor reallocation since it takes time for workers to find new jobs some unemployment is unavoidable this paper presents evidence that most of the unemployment fluctuations of the seventies unlike those in the sixties were induced by unusual structural shifts within the u s economy simple time series models of layoffs and unemployment are constructed that include a measure of structural shifts within the labor market these models are estimated and a derived natural rate series is constructed

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

the economics of vocation or why is a badly paid nurse a good nurse abstract given the longstanding shortage of nurses in many jurisdictions why could not nursing wages be raised to attract more people into the profession we tell a story in which the status of nursing as a vocation implies that increasing wages reduces the average quality of applicants attracted the underlying mechanism accords with the notion that increasing wages might attract the wrong sort of people into the profession and highlights an in efficiency wage mechanism particular to vocations which makes wages sticky up wards the analysis has implications for job design in vocation based sectors such as nursing and teaching

clubs local public goods and transportation models a synthesis abstract clubs local public goods and transportation models are analyzed within a unified model the emphasis is on the derivation of optimal allocation pricing and the size of the sharing group we derive the conditions under which optimal prices will yield surplus or deficit as well as those under which competitive provision will be efficient given heterogeneous tastes we prove that segregation according to tastes is generally efficient although several cases where this result does not hold are also discussed we show that the existing literature is unnecessarily restrictive and that the unified approach suggested here considerably extends the existing analysis of clubs local public goods and the transportation problems

durable goods investment shocks and the comovement problem sticky price models suggest that capital investment shocks are an important driver of business cycle fluctuations despite quantitative importance in explaining business cycles a comovement problem emerges because the shocks generate intertemporal substitution effects away from consumption toward investment this paper resolves the problem by extending the standard sticky price model to a two sector model with consumer durable services when durable goods are used as investment in capital and consumer durables positive capital investment shocks also generate intratemporal substitution effects away from consumer durable services toward nondurable consumption that dominates intertemporal effects consequently consumption increases and the comovement problem is resolved

durable goods inter sectoral linkages and monetary policy barsky house and kimball 2007 show that introducing durable goods into a sticky price model leads to negative sectoral comovement of production following a monetary policy shock and under certain conditions to aggregate neutrality these results appear to undermine sticky price models in this paper we show that these results are not robust to two prominent and realistic features of the data namely input output interactions and limited mobility of productive inputs when extended to allow for both features the sticky price model with durable goods delivers implications in line with var evidence on the effects of monetary policy shocks

house prices borrowing constraints and monetary policy in the business cycle i develop a general equilibrium model with sticky prices credit constraints nominal loans and asset prices changes in asset prices modify agents borrowing capacity through collateral value changes in nominal prices affect real repayments through debt deflation monetary policy shocks move asset and nominal prices in the same direction and are amplified and propagated over time the financial accelerator is not constant across shocks nominal debt stabilises supply shocks making the economy less volatile when the central bank controls the interest rate i discuss the role of equity debt indexation and household and firm leverage in the propagation mechanism finally i find that monetary policy should not target asset prices as a means of reducing output and inflation volatility

a near rational model of the business cycle with wage and price inertia this paper presents a model in which insignificantly suboptimal behavior causes aggregate demand shocks to have significant real effects the individual loss to agents with inertial price wage behavior is second order in terms of the parameter describing the shock while the effect on real economic variables is first order thus significant changes in business activity can be generated by anticipated money supply changes provided that some agents are willing to engage in nonmaximizing behavior which results in small losses

size structure and administrative overheads an empirical analysis of english local authorities the relationship is analysed between size local government structure and administrative overheads in english local authorities size and structure effects are tested while controlling for a range of other variables including the relative prosperity of the local population and the diversity of their service needs the empirical results show that population size consistently has a linear negative effect central administrative costs are lower in larger local authorities the results also show that controlling for size administrative overheads are higher for councils in the lower tier of the existing two tier system the analysis provides support for arguments that economies of scale might be achieved by amalgamating smaller councils into larger units and by combining counties and districts into unitary authorities

investment shocks and business cycles abstract the origins of business cycles are still controversial among macroeconomists this paper contributes to this debate by studying the driving forces of fluctuations in an estimated new neoclassical synthesis model of the u s economy in this model most of the variability of output and hours at business cycle frequencies is due to shocks to the marginal efficiency of investment imperfect competition and to a lesser extent technological frictions are the key to their transmission although labor supply shocks explain a large fraction of the fluctuations in hours at very low frequencies they are irrelevant over the business cycle this finding is important because the microfoundations of these disturbances are widely regarded as unappealing

unemployment and the efficiency wage hypothesis there has been much recent discussion of the reasons why prices in certain markets and in particular in labour markets may not adjust to eliminate excess supply the absence of speedy adjustment of prices is an essential feature of the recent models of disequilibrium macroeconomics but for the most part no explanation for this absence is provided from within those models one explanation that has been around in the literature for some time and has been receiving increasing attention recently is the efficiency wage hypothesis initially applied to developing economies see leibenstein i957 it has more recently been adapted to developed economies by weiss i 980 and used in the context of a keynesian macroeconomic model by hart i 980 similar concepts have been applied to the credit market by stiglitz and weiss i98i the purpose of the present paper is to explore further the conditions under which the notion of an efficiency wage is applicable and can provide an explanation of involuntary unemployment the essential feature of the efficiency wage hypothesis is that the productivity of a firm s employees increases as their wage is increased at least over an economically relevant part of its range if the wage paid by the firm is denoted by w the number of employees by l and the productivity of each employee by p w where p w o then the effective labour force of the firm e can be represented by

canadian jobs and firm size do smaller firms pay less even after controlling for observable workers characteristics and for occupation and industry specific effects a substantial wage differential remains between large and small firms what underlies the remaining wage differential is unclear direct evidence on pension plan coverage and on lay off rates by firm size is inconsistent with the bad working conditions hypothesis the union avoidance hypothesis does not seem to explain an important portion o f the wage differential as suggested by efficiency wage models part of the remaining wage differential may be due to firms heterogeneity similarly perhaps large firms pay higher wages simply partly beca use they employ workers with more unobserved abilities because differen t explanations of the wage differential may lead to different policy implications determining the source of the wage firm size effect is an important question for future research

local authority fiscal stance and the pattern of residential migration in the north west of england the degree of fiscal mobility present in household migration flows between local authority areas in northwestern england is assessed following an introduction the paper is divided into three sections the first reviews the methodologies of previous attempts to assess the extent of fiscally induced migration noting the dominance of american studies and outlines a choice theoretic structure within which it is possible to model human migration patterns section iii considers the problems inherent in modelling migration flows and section iv presents results for a compound poisson analysis of migration between local authority areas within the four counties of the north west region of england as well as an assessment of the prevalence of fiscal mobility excerpt

new keynesian economics and the phillips curve models with sticky prices are an important part of new keynesian economics the author shows that several of the new keynesian models imply a formulation that is similar to the expectations augmented phillips curve of milton friedman and edmund phelps he then presents new estimates of the new keynesian phillips curve the author uses two proxies for price expectations survey based measures and an econometric based measure originally developed by bennett mccallum 1976 overall the results are consistent with the model but the survey based results are more precise suggesting that the surveys may be better measures of actual expectations copyright 1995 by ohio state university press

the time varying volatility of macroeconomic fluctuations we investigate the sources of the important shifts in the volatility of us mac roeconomic variables in the postwar period to this end we propose the esti mation of dsge models allowing for time variation in the volatility of the structural innovations we apply our estimation strategy to a large scale model of the business cycle and find that shocks specific to the equilibrium condition of investment account for most of the sharp decline in volatility of the last two decades jel c51 e32

macroeconomic adjustment with segmented labor markets this paper analyzes the macroeconomic effects of fiscal and labor market policies in a developing economy with an informal sector and a heterogeneous work force a permanent reduction in government spending on nontraded goods leads in the long run to a deprecia tion of the real exchange rate a fall in the market clearing wage for unskilled labor an increase in output of traded goods and a lower stock of net foreign assets a permanent reduction in the minimum wage improves competitiveness and expands the formal sector the effect of changes in unemployment benefits are also analyzed q 1999 elsevier science

sticky price and limited participation models of money a comparison abstract we provide new evidence that models of the monetary transmission mechanism should be consistent with at least the following facts after a contractionary monetary policy shock the aggregate price level responds very little aggregate output falls interest rates initially rise real wages decline by a modest amount and profits fall we compare the ability of sticky price and limited participation models with frictionless labor markets to account for these facts the key failing of the sticky price model lies in its counterfactual implications for profits the limited participation model can account for all the above facts but only if one is willing to assume a high labor supply elasticity 2 percent and a high markup 40 percent the shortcomings of both models reflect the absence of labor market frictions such as wage contracts or factor hoarding which dampen movements in the marginal cost of production after a monetary policy shock 1997 elsevier science b v

sticky price models and durable goods the inclusion of a durable goods sector in sticky price models has strong and unexpected implications even if most prices are flexible a small durable goods sector with sticky prices may be sufficient to make aggregate output react to monetary policy as though most prices were sticky in contrast flexibly priced durables with sufficiently long service lives can undo the implications of standard sticky price models in a limiting case flexibly priced durables cause monetary policy to have no effect on aggregate output our analysis suggests that durable goods prices are the most relevant data for calibrating price rigidity jel e21 e23 e31 e52

involuntary unemployment and worker self selection abstract consider a firm that lacks information about the reservation wage or ability of any specific worker but is aware that workers with higher reservation wages tend to be more able on average we show that under a simple condition that the efficiency wage exceeds the lowest reservation wage the optimal hiring policy for the firm involves 1 no wage discrimination and 2 rationing of jobs when demand for its product is low the result also extends to the case where hours of work are variable provided each worker is most productive when working a strictly positive number of hours per week

equilibrium and inefficiency in a community model with peer group effects public service output depends on input expenditures on own personal characteristics and on the characteristics of the other residents in the community the peer group effect in a community model with public expenditures set by voting with migration between communities and with land price differentials capitalization it is shown that communities may become heterogeneous in composition and second best inefficient this equilibrium occurs when the peer group effect is neither too strong nor too weak the inefficiency arises because an externality is created by migration the land price differential does not play the part of the price of the better peer group but of a transfer payment

investment shocks and the comovement problem recent work based on sticky price wage estimated dynamic stochastic general equilibrium dsge models suggests investment shocks are the most important drivers of post world war ii us business cycles consumption however typically falls after an investment shock this finding sits oddly with the observed business cycle comovement where consumption along with hours worked and investment moves with economic activity we show that this comovement problem is resolved in an estimated dsge model when i the cost of capital utilization is specified in terms of increased depreciation of capital as originally proposed by greenwood et al 1988 in a neoclassical setting or ii there is no wealth effect on labor supply the data however favors the first channel traditionally the cost of utilization is specified in terms of forgone consumption following christiano et al 2005 who studied the effects of monetary policy shocks the alternative specification we consider has two additional implications relative to the traditional one i it has a substantially better fit with the data and ii the contribution of investment shocks to the variance of consumption is over three times larger the contributions to output investment and hours are also relatively higher suggesting that these shocks may be quantitatively even more important than previous estimates based on the traditional specification

efficiency wages deferred payments and direct incentives in agriculture empirical evidence from agricultural labor markets is consistent with efficiency wage theory and inconsistent with several alternative explanations according to this theory the higher wage or deferred payment benefits that direct hire growers pay relative to that of farm labor contractors is an efficiency wage growers use this extra compensation to lower their monitoring expenses and reduce shirking by workers copyright 2002 oxford university press

a critique of tiebout s theory of local public expenditures the last section of this paper presents a rigorous version of tiebout s theory of local public goods it is shown that equilibria exist and are pareto optimal this rigorous theory follows closely the more rigorous part of tiebout s work this rigorous theory makes a number of very special assumptions which make local public goods essentially private the body of this paper presents a series of examples which show that if one tries to generalize the rigorous version of tiebout s theory in a number of interesting directions then equilibria may no longer exist or may not be pareto optimal the conclusion is that tiebout s idea does not lead to a satisfactory general theory of local public goods the goal of this paper is to point out that tiebout s notion of equilibrium with local governments does not have the nice properties of general competitive equilibrium except under very restrictive assumptions tiebout 39 suggested that there are competitive forces which tend to make local governments allocate resources in a pareto optimal fashion consumers choose to live in those towns with the mix of taxes and public goods they prefer local governments choose this mix so as to attract inhabitants this idea may seem intriguing for it suggests that the invisible hand solves an important part of samuelson s perplexing public goods problem 32 tiebout in fact makes an argument which is nearly rigorous i give a rigorous version of his argument at the end of the paper however in this rigorous version so many restrictive assumptions are made that public goods become essentially private in the body of the paper i give a series of examples with which i try to convince the reader that one is forced to adopt tiebout s restrictive assumptions the idea is that if one changes any of his assumptions then either equilibria may not exist or may not be pareto optimal my examples are presented in the context of a general class of tiebout models i consider several subclasses one of which is the special case considered by tiebout in each of the subclasses except that considered by tiebout i give a counterexample either to the existence of equilibrium or to its pareto optimality the subclasses are so chosen that the difficulties they reveal would be shared by any reasonable tiebout model which differed from his special case i believe that my examples controvert tiebout s suggestion 39 last paragraph that his theory compares favorably with competitive equilibrium theory most of the examples in this paper have already appeared in the literature i cite related work as i go along what is new here is that i assemble the examples in a unified argument

local government structure and urban residential location the large research literature on the tiebout model has developed with little attention paid to the urban economic structure in which local government functions this paper attempts to examine the theoretical consequences of local jurisdictions functioning within a conventional monocentric urban model it also discusses a mathematical formulation of a two jurisdiction linear city in which the local service level and local property tax rate might be used as strategic variables in a game theory sense it is concluded that for this to happen the local service level has to have more than one element which is intuitively appealing some references are developed to current british local government and possible changes

the dynamic effects of neutral and investment specific technology shocks the neoclassical growth model is used to identify the short run effects of neutral technology shocks which affect the production of all goods homogeneously and investment specific shocks which affect only investment goods the real equipment price crucial for identifying the investment shocks experiences an abrupt increase in its average rate of decline in 1982 so the analysis is based on a split sample on the basis of the preferred specification the two technology shocks account for 73 percent of hours and 44 percent of output s business cycle variation before 1982 and 38 percent and 80 percent afterward the shocks also account for more than 40 percent of hours and 58 percent of output s forecast errors over a three to eight year horizon in both samples the majority of these effects are driven by the investment shocks

wage interdependence through decentralized bargaining abstract the idea that sector specific unions are influenced by the wages obtained by other unions has mainly been used to support the empirical observation that wages are highly correlated among industries the sources of wage interdependence can mainly be found in unions preferences in the nature of technology and in price and demand determination the presence of externalities and of strategic complementarity among unions leads to suboptimal equilibria which generates non desired inflation unemployment and possibly also trade balance deficit this enforces the idea that part of current unemployment can be eliminated by improving the cooperation between social actors

efficiency wage models of unemployment keynesian economists hold it to be self evident that business cycles are characterized by involuntary unemployment but construction of a model of the cycle with involuntary unemployment faces the obvious difficulty of explaining why the labor market does not clear involuntarily unemployed people by definition want to work at less than the going wage rate why don t firms cut wages thereby increasing profits

forecasting housing prices under different market segmentation assumptions three types of market segmentation strategies are available to estimate hedonic housing price models i e no segmentation segmentation by using statistical clustering methods and segmentation by using a priori information this research tests the hypothesis of tiebout theory that individual residential decision making is determined by equilibrium provision of local public goods in accord with the tastes and preferences of residents thereby sorting their housing locations into optimal sub markets forecasting accuracies of eight sub market segmentation strategies and two forecast combining methods are examined by using housing sales data from knox county tennessee usa the results provide empirical support for tiebout theory of optimal housing sub market location in that boundaries drawn using a priori information from local government jurisdictions school districts and expert opinions are more closely aligned with the equilibrium provision of local public goods than boundaries drawn by statistical cl

small menu costs and large business cycles a macroeconomic model of monopoly i introduction the conflict between modern neoclassical and traditional keynesian theories of the business cycle centers upon the pricing mechanism in neoclassical models prices are fully flexible they represent the continuous optimization of economic agents and the continuous intersection of supply and demand in keynesian models prices are often assumed to be sticky they do not necessarily equilibrate all markets at all times one of the reasons for the resurgence of the equilibrium approach to macroeconomics has been the absence of a theoretical underpinning for this keynesian price stickiness this note shows that sticky prices can be both privately efficient and socially inefficient the business cycle results from the suboptimal adjustment of prices in response to a demand shock to the extent that policy can stabilize aggregate demand it can mitigate the social loss due to this suboptimal adjustment in some keynesian models prices are simply exogenously fixed 2 in others agents must set their prices in advance of the transaction date the act of altering a posted price is certainly costly these costs include such items as printing new catalogs and informing salesmen of the new price yet these menu costs are small and therefore generally perceived as providing only a weak foundation for these fixed price models however this inference is flawed small menu costs can cause large welfare losses the claim that price adjustment costs are small does not rebut the claim that they are central to understanding economic fluctuations

modeling investment sector efficiency shocks when does disaggregation matter the most straightforward way to analyze investment sector productivity developments is to construct a two sector model with a sector specific productivity shock an often used modeling shortcut accounts for such developments using a one sector model with shocks to the efficiency of investment in a capital accumulation equation this shortcut is theoretically justified when some stringent conditions are satisfied using a two sector model we consider the implications of relaxing several of the conditions that are at odds with the u s input output tables including equal factor shares across sectors the effects of productivity shocks to an investment producing sector of our two sector model differ from those of efficiency shocks to investment in a one sector model notably expansionary productivity shocks boost consumption in every period whereas expansionary efficiency shocks cause consumption to fall substantially for many periods

on the fit of new keynesian models this article provides new tools for the evaluation of dynamic stochastic general equilibrium dsge models and applies them to a large scale new keynesian model we approximate the dsge model by a vector autoregression and then systematically relax the implied cross equation restrictions and document how the model fit changes we also compare the dsge model s impulse responses to structural shocks with those obtained after relaxing its restrictions we find that the degree of misspecification in this large scale dsge model is no longer so large as to prevent its use in day to day policy analysis yet is not small enough to be ignored

responders versus non responders a new perspective on heterogeneity this paper considers the implications of a particular type of heterogeneity one which characterizes a large number of economic environments but that has not received any systematic treatment in the literature the authors refer to this heterogeneity as responders versus nonresponders the paper begins by providing a general framework for the analysis of environments characterized by this heterogeneity and then shows how this framework can be used to help understand a wide variety of economic environments particular applications considered are near rationality network externalities and models of reputation copyright 1991 by royal economic society

property taxation nash equilibrium and market power abstract differences in tax policy arise from differences in the number of jurisdictions in a metropolitan area following wildasin 4 and bucovetsky 2 the tax rates in the jurisdictions are determined in a nash game in the tax rate the tax rate and public service level as well as the welfare of residents increase as the number of jurisdictions in the metropolis decreases

a model of the natural rate of unemployment since the publication of edmund phelps volume the new macroeconomics has treated the labor market as a dynamic process of rational search by unemployed workers for available vacancies wages are viewed as at least potentially flexible though free contracting between workers and firms may lead to fixed wages in the short run imperfect information is a crucial element of the theory for it implies both a need for contracting and a need for rational search rather than simple market clearing in each period a positive rate of frictional unemployment may exist in equilibrium denoted as the natural rate this unemployment is due to the frictions in the search process and imperfections in information rather than to any deficiency in aggregate demand milton friedman defined the natural rate as the level that would be ground out by the walrasian system of general equilibrium equations provided there is embedded in them the actual structural characteristics of the labor and commodity markets including market imperfections stochastic variability in demands and supplies the cost of gathering information about job vacancies and labor availabilities the costs of mobility and so on p 8 this paper reexamines the micro foundations of the natural rate in a model of labor market equilibrium in which turnover flows and imperfect information are explicitly considered workers may quit their current jobs to enter the unemployment pool in order to search among available vacancies for a more preferred position firms economize on turnover by an appropriate wage policy

labor contracts under asymmetric information when workers are free to quit this paper examines the impact of workers ability to quit on the performance of labor contracts between workers and privately informed firms while the need to induce workers to remain with the firm necessarily lowers total welfare the effect on employment levels is to reduce the magnitude of the inefficiency due to asymmetric information whether this inefficiency is under or overemployment the model predicts that employment distortions increase with the strength of lock in effects on workers a prediction which contrasts with the results of efficiency wage models and which may help in empirical testing of labor contract theory

temporary investment tax incentives theory with evidence from bonus depreciation even modest reductions in the after tax cost of capital purchases provide strong incentives for increased investment indeed for tax subsidies that are temporary and for capital goods that are very long lived the incentive to invest when the after tax price is temporarily low is essentially infinite firms that would have purchased new capital equipment in the future instead make their purchases during the period of the subsidy for tax increases the effects are the opposite firms that would have normally invested now delay until the tax rate returns to normal we present a model of the equilibrium effects of temporary investment tax incentives the model reveals a simple relationship between the shadow price of investment goods and the size of a temporary investment tax incentive specifically for sufficiently long lived capital goods goods with very low rates of economic depreciation and for sufficiently short lived investment tax subsidies the shadow value of capital should be nearly unchanged and thus the pre tax shadow price of capital goods should fully reflect the magnitude of the tax subsidy this result holds regardless of the elasticity of investment supply and regardless of the underlying demand for capital instead it relies only on the firm s ability to arbitrage predictable movements in the after tax price of long lived capital over time two conclusions immediately follow first observ ing price increases following a temporary tax incentive is not evidence that investment supply is relatively inelastic a temporary investment tax subsidy can substantially affect investment even if it bids up the price of investment sharply second because economic theory dictates that the shadow price of investment moves one for one with a temporary tax subsidy the elasticity of supply can be inferred from quantity data alone recent changes in us tax law allow us to use the model and its implications to estimate struc tural parameters that govern the supply of investment the 2002 and 2003 tax bills provided temporarily accelerated tax depreciation called bonus depreciation for certain types of qualified capital goods under the 2002 bill firms could immediately deduct 30 percent of investment purchases and then depreciate the remaining 70 percent under standard depreciation schedules
