tracking the new economy using growth theory to detect changes in trend productivity abstract the acceleration of productivity after 1995 prompted a debate over whether the economy s underlying growth rate would remain high in this paper we draw on growth theory to identify variables other than productivity namely consumption and labor compensation to help estimate trend productivity growth we treat that trend as a common factor with two regimes high and low growth our analysis picks up striking evidence of a return in 1997 to the high growth regime nearly 25 years after a switch from high to low growth we find that both the common factor and regime switching aspects of the model are important for identifying changes in trend productivity and also show that the trend breaks are more difficult to detect with per capita as opposed to per hour based data because of persistent labor supply shifts finally we argue that our methodology is effective in detecting changes in trend in real time in the case of the 1990s the methodology would have signaled the regime switch by 1999 or within roughly six quarters of when it occurred according to the full sample

are church and state substitutes evidence from the 1996 welfare reform abstract churches provide community services similar to those provided by the government but there has been no convincing analysis of the extent to which church activity can substitute for government activity to address this important issue this paper uses a new panel data set of presbyterian church usa congregations to regress both church member donations and a church s community spending on a number of variables including government welfare expenditures a provision of the 1996 welfare law that decreased the availability and use of welfare services by non citizens serves as an instrument to identify the causal effect of government spending on church activity the results show that church activities substitute for government activities extrapolating the findings to all denominations the estimated crowd out effect lies between 20 and 38 cents on the dollar the results are subjected to a number of robustness tests

trend growth expectations and u s house prices before and after the crisis abstract we provide an analysis that might help distinguish rationally justified movements in house prices from potentially non rational movements using a two sector business cycle model in which investment in housing is subject to collateral constraints a large portion of the evolution of u s house prices during the past 20 years can be reproduced when expectations of future income growth as published in surveys are used as an input into the model changes in growth expectations translate into corresponding changes in house prices since the value of housing must be linked to expected aggregate income only since about 2005 do actual and model implied house prices clearly diverge calling for explanations not based on economic fundamentals

religious participation and children s education a social capital approach abstract based on the argument in both economic and sociological literature that religion is conducive to children s human capital formation this paper provides a model of religious participation and explores a mechanism that social capital affects children s education a la coleman coleman j s 1988 social capital in the creation of human capital american journal of sociology 94 s95 s120 the model generates several interesting implications which help explain some important stylized facts about education and religion further in a dynamic setting the model shows that there exists a steady state in which individuals allocate a positive amount of time and resources to religious activities thus it complements the existing literature to explain why seemingly unproductive religions can be everlasting

using elasticities to derive optimal income tax rates this paper derives optimal income tax formulas using compensated and uncompensated elasticities of earnings with respect to tax rates a simple formula for the high income optimal tax rate is obtained as a function of these elasticities and the thickness of the top tail of the income distribution in the general non linear income tax problem this method using elasticities shows precisely how the different economic effects come into play and which are the key relevant parameters in the optimal income tax formulas of mirrlees the optimal non linear tax rate formulas are expressed in terms of elasticities and the shape of the income distribution these formulas are implemented numerically using empirical earning distributions and a range of realistic elasticity parameters

income maintenance and labor force participation the paper studies the optimal tax subsidy schedules in an economy where the only decision of the agents is to work or not with an application to the case of france given an income guarantee provided by the welfare state the tax schedule that maximizes government revenue provides a benchmark the laffer bound above which it is inefficient to tax in fact under mild conditions a feasible allocation is second best optimal if and only if the associated taxes are lower than the laffer bound the only restriction that efficiency puts on the shape of the tax scheme is this upper laffer bound the laffer tax scheme itself can be computed from the joint distribution of the agents productivities and work opportunity costs depending on the economy it can take widely different forms and exhibit for instance negative marginal tax rates after estimating the joint distribution of productivities and work opportunity costs on french data i compute the laffer bound for two subpopulations single women and married women with two children or more quite surprisingly the actual incentives to work appear to be very close to the bound

decomposition of productivity and unit costs labor productivity output per hour in the private nonfarm business sector is reported to have been rising at an annual rate of about 1 percent since 1973 at the same time output per hour in the nonfinancial corporate sector is estimated to have been increasing at a 13 4 percent annual rate given that the nonfinancial corporate sector is about two thirds of the aggregate these statistics imply that output per hour elsewhere in private business has not increased on average for more than two decades because it seems unlikely that major sectors of the economy have failed to become more efficient over the years it would be useful to try to identify at a more disaggregated level those segments of the economy with persistently dismal measured productivity performance this paper presents such a disaggregation the decompositions are by legal form of organization with gross industry breaks within the corporate sector and by detailed industry for expository convenience we refer to the former as the sectoral decomposition and the latter as the industry decomposition

friedman s plucking model of business fluctuations tests and estimates of permanent and transitory components in milton friedman s model output cannot exceed a ceiling level but occasionally is plucked downward by recession implying fluctuations are asymmetric recessions transitory and recessions duration dependent though expansions are not the empirical literature lends support but formal modeling has been absent the econometric model presented here encompasses both plucking and symmetric fluctuations around a stochastic trend we find gdp is well characterized by the plucking model implied recessions correspond to nber reference cycles and no role for symmetric cycles decomposition of the unemployment rate reveals a corresponding asymmetry and timing paths of ceiling output and trend unemployment are presented

mr smith and the preachers the economics of religion in the wealth of nations the extension of economic analysis to problems beyond the domain of formal markets and explicit prices represents a major recent intellectual development but economic imperialism is not new and was not invented in chicago adam smith in his wealth of nations extended economic reasoning to a variety of nonmarket exchange problems one example is his analysis of religious behavior smith viewed participation in religion as a rational device by which individual enhanced the value of their human capital he also explained the behavior of the clergy and other suppliers of religious services from an economic perspective

religious adherence and county economic growth in the us abstract we estimate a barro type conditional convergence model using religious adherence data from the american religious data archive to analyze independent effects of church adherence rates on economic growth in the united states at the county level per capita income growth is modeled as a function of initial per capita income initial human capital stock and a set of control and related variables including religious adherence religious diversity and regional indicator variables we also investigate the independent effects of three main denominations namely catholics evangelical christians and mainline christians on county economic growth our results indicate that the religious adherence in general is significantly greater than zero and not beneficial for us county income growth we find mixed results for effects of various denominations

the economic organization of the english east india company abstract alfred chandler and oliver williamson pioneered the argument that the invention of the multidivisional firm in the 1920 s in the u s was a major organizational innovation in this paper we argue that the organizational principles underlying the multidivisional firm appeared much earlier in history specifically in the organization of the english east india company we document the presence of multidivisional principles in the east india company and we argue that most likely the company evolved to a divisionalized basis because of its monopoly status with respect to the sale of asian goods in england

self selection and pareto efficient taxation abstract this paper analyses the set of pareto efficient tax structures the formulation of the problem as one of self selection not only shows more clearly the similarity between this problem and a number of other problems such as the optimal pricing of a monopolist which have recently been the subject of extensive research but also allows the derivation of a number of new results we establish i under fairly weak conditions randomization of tax structures is desirable ii if different individuals are not perfect substitutes for one another in production then the general equilibrium effects until now largely ignored in the literature of changes in the tax structure may be dominant in determining the optimal tax structure in particular if the relative wage of high ability and low ability individuals depends on the relative supplies of labor the optimal tax structure entails a negative marginal tax rate on the high ability individuals and a positive marginal tax rate on the low ability individuals the marnitude of which depends on the elasticity of substitution iii if individuals differ in their preferences pareto efficient taxation may entail negative marginal tax rates for high incomes while iv if wage income is stochastic the marginal tax rate at the upper end may be 100 our analysis thus makes clear that the main qualitative properties of the optimal tax structure to which earlier studies called attention are not robust to these attempts to make the theory more realistic

optimal incentives for labor force participation abstract optimal taxation is analyzed under a rawlsian criterion in an economy where the only decision of the agents is to participate or not to the labor force the model allows for heterogeneity both in the agent s productivities and aversions to work at a first best optimal schedule the marginal agent who decides to work pockets all of her productivity while being just compensated for her work aversion when the planner does not observe work aversion financial compensation for work is lower than productivity theory puts little restrictions on the shape of the optimal tax schedules the usual first order conditions involving the elasticities of participation only apply for sufficiently regular economies we qualitatively show how the optimal incentive schemes depend on the underlying structure of the preferences 100 marginal tax rates or subsidies to work are related to specific features of the economies

viewpoint innovations in the theory and practice of redistribution policy we present a survey of key results from second best optimal redistribution theory and their implications for tax transfer policy the core results include the corlett hague theorem the deaton conditions the production efficiency theorem the atkinson stiglitz theorem and the mirrlees saez characterization of the optimal non linear income tax system these have been augmented in recent years by optimal participation tax rates the implications of involuntary unemployment the use of unconventional instruments such as minimum wages in kind transfer and workfare and the optimal taxation of capital income and bequests l auteur presente un survol des principaux resultats theoriques de la redistribution optimale de second ordre et de leurs implications pour les politiques d imposition et de transferts les resultats fondamentaux incluent le theoreme de corlett hague les conditions de deaton les theoremes d efficacite en production le theoreme d atkinson stiglitz ainsi que la caracterisation du systeme optimal d imposition non lineaire du revenu a la mirrlees saez ces derniers resultats ont ete enrichis au cours des dernieres annees par certains autres portant sur les taux d imposition decoulant des allocations conditionnelles les implications du chomage involontaire l usage d instruments non conventionnels tels que le salaire minimum les transferts en nature le workfare ainsi que l imposition optimale des revenus du capital et des legs ces resultats sont exposes et leurs implications pour les politiques d imposition et de transferts sont discutees

optimal nonlinear income taxation with learning by doing abstract this paper examines a two period model of optimal nonlinear income taxation with learning by doing in which second period wages are an increasing function of first period labour supply we consider the cases when the government can and cannot commit to its second period tax policy in both cases the canonical mirrlees stiglitz results regarding optimal marginal tax rates generally no longer apply in particular if the government cannot commit and each consumer s skill type is revealed it is optimal to distort the high skill type s labour supply downwards through a positive marginal tax rate to relax an incentive compatibility constraint our analysis therefore identifies a setting in which a positive marginal tax rate on the highest skill individual can be justified despite its depressing effect on both labour supply and wages

relativity mobility and optimal nonlinear income taxation in an open economy abstract recent evidence suggests that globalization has reduced the barriers to international labor mobility and induced more cross country social comparisons in an open economy with tax driven migration and consumption externalities relativity we derive an optimal tax formula that subsumes existing ones obtained under a maximin social objective and additively separable utility and sign the second best mirrleesian marginal tax rates for all skill levels we establish the thresholds of the elasticity and level of migration to determine when relativity and inequality act as complements or substitutes in shaping the optimal top tax rate under both nash and stackelberg tax competition if the migration probability of top income workers is approximately 50 numerical calculation using parameter estimates from empirical studies shows that the country with labor inflow outflow implements over 10 lower higher marginal tax rates than suggested by the autarky equilibrium of kanbur and tuomala 2013

sovereign default the role of expectations we study a variation of the standard model of sovereign default as in aguiar and gopinath 2006 or arellano 2008 and show that this variation is consistent with multiple interest rate equilibria some of those equilibria correspond to the ones identi ed by calvo 1988 where default is likely because rates are high and rates are high because default is likely the model is used to simulate equilibrium movements in sovereign bond spreads that resemble sovereign debt crises it is also used to discuss lending policies similar to the ones announced by the european central bank in 2012

stochastic trends and economic fluctuations are business cycles mainly the result of permanent shocks to productivity this paper uses a long run restriction implied by a large class of real business cycle models identifying permanent productivity shocks as shocks to the common stochastic trend in output consumption and investment to provide new evidence on this question econometric tests indicate that this common stochastic trend cointegration implication is consistent with postwar u s data however in systems with nominal variables the estimates of this common stochastic trend indicate that permanent productivity shocks typically explain less than half of the business cycle variability in output consumption and investment copyright 1991 by american economic association

optimal marginal and average income taxation under maxi min using the mirrlees optimal income tax model with a maxi min social welfare function we derive conditions for a decreasing marginal tax rate throughout the skill distribution a strictly concave tax function in income and a single peaked average tax schedule with additive preferences and a constant labor supply elasticity marginal tax rates are decreasing below the modal skill level and will also decrease above the mode if aggregate skills are non decreasing with the skill level in this case and with a bounded skill distribution or with a constant hazard rate the tax function is strictly concave in income and the average tax rate single peaked when quasilinear utility functions apply in either consumption or leisure under fairly mild restrictions on the truncated or untruncated distribution function marginal tax rates are decreasing in skill and the average tax profile is single peaked the distribution of skills has the same quantitative influence for either case of quasilinearity these results continue to hold when there is bunching at the bottom due to a binding non negativity constraint we also illustrate how relaxing the assumption of constant elasticity of labor supply generally used in the literature modifies the results

measures of per capita hours and their implications for the technology hours debate structural vector autoregressions give conflicting results on the effects of technology shocks on hours the results depend crucially on the assumed data generating process for hours per capita we show that the standard measure of hours per capita and productivity have significant low frequency movements that are the source of the conflicting results hodrick prescott hp filtered hours per capita produce results consistent with those obtained when hours are assumed to have a unit root we show that important sources of the low frequency movements in the standard measure are sectoral shifts in hours and the changing age composition of the working age population when we control for these low frequency components to determine the effect of technology shocks on hours using long run restrictions we get one consistent answer hours decline in the short run in response to a positive technology shock we further extend the analysis by examining the effects of demographic controls on the impulse responses to investment specific technology shocks our results are less conclusive

the new econometrics of structural change dating breaks in u s labor productivity we have seen the emergence of three major innovations in the econometrics of structural change in the past fifteen years 1 tests for a structural break of unknown timing 2 estimation of the timing of a structural break and 3 tests to distinguish unit roots from broken time trends these three innovations have dramatically altered the face of applied time series econometrics in this paper we review these three innovations and illustrate their application through an empirical assessment of u s labor productivity in the manufacturing durables sector

the expectations driven us current account during the 1990s and 2000s survey expectations of long run output growth for the u s relative to the rest of the world were highly correlated with the u s current account and thus with global imbalances we show that this finding is to a large extent predicted by a two region stochastic growth model simulated using expected trend growth based on surveys in line with the intertemporal approach to the current account a major part of the buildup and subsequent reversal of the u s current account de cit appears to be consistent with an optimal response of households and firms to changing growth prospects this article is protected by copyright all rights reserved

stochastic technical progress smooth trends and nearly distinct business cycles this paper studies a model of random technical progress where technology diffuses at realistically slow rates it fits smooth trends to the sum of gdp series generated by this model and series representing transitory or cyclical fluctuations detrended gdp is then largely unrelated to technical progress the detrending method proposed by rotemberg 1999 reconstructs cyclical variations somewhat more accurately than the hp filter with sufficiently slow diffusion it is also more accurate than a method based on vars fitted to hours and gdp growth consistent with the model s predictions permanent shocks initially depress both hours and output in these vars

optimal income taxation an example with a u shaped pattern of optimal marginal tax rates comment using the mirrlees optimal income tax model with quasi linear preferences the paper examines conditions for marginal tax rates to be rising at high income levels and declining in an interval containing the modal skill it examines conditions for the marginal tax rate to be higher at a low skill level than at the high skill level with the same density an argument only holding for skill levels above a cutoff where resources of a worker are marginally of the same value as resources of the government data on earnings rates are presented copyright 1998 by american economic association

a reduced form optimal nonlinear income tax problem abstract for a finite population with quasilinear preferences it is shown how mirrlees optimal nonlinear income tax problem can be simplified to a reduced form problem involving only the allocation of the consumption good this result is a finite version of a proposition established in the continuum by s lollivier and j c rochet

technological revolutions and the three great slumps a medium run analysis abstract the great recession the great depression and the japanese slump of the 1990s were all preceded by periods of major technological innovation which happened about 10 years before the start of the decline in economic activity we estimate a model with noisy news we find that beliefs about long run income adjust to permanent shifts in productivity with an important delay the estimation tells a common and simple story for the observed dynamics of productivity and consumption on a 20 to 25 year window our analysis highlights the advantages of a look at this data from the point of view of the medium run

a general characterization of optimal income tax enforcement this paper develops a general approach to characterizing optimal income tax and enforcement schemes our analysis clarifies the nature of the interplay between tax rates audit probabilities and penalties for misreporting in particular it is shown that for a variety of objective functions for the principal the optimal tax schedule is in general concave at least weakly and monotonic the marginal tax rates determine the audit probabilities and less harsh penalties lead to higher enforcement costs our results imply that there exists a tradeoff between equity and efficiency considerations in the enforcement context which is similar to that in the moral hazard context for tax policy it is well accepted by now that informational asymmetries generate important constraints on the formulation of economic policy an early and classic example is given by mirrlees 1971 who considers the problem of optimal income taxation when individuals differ in their ability to transform effort into income it is assumed that ability and effort of an individual cannot be observed at any cost whereas income which is the product of these two unobservables is perfectly and costlessly observable taxes can thus depend only on final income under these informational conditions the equity efficiency tradeoffs that constrain the choice of tax policy arise only because of the presence of moral hazard associated with taxation of income if there were no moral hazard i e individual efforts and therefore incomes were exogenous the problem of optimal income taxation would be a trivial one since by assumption individual incomes are perfectly and costlessly observable in much of the recent literature on optimal income taxation in the presence of costly enforcement reinganum and wilde 1985 border and sobel 1987 and others on the other hand individual incomes are treated as exogenous i e there is no moral hazard however informational constraints arise from another important consideration namely an individual s income cannot be directly observed it can only be verified through a costly

measuring the natural rate of interest international trends and determinants abstract u s estimates of the natural rate of interest the real short term interest rate that would prevail absent transitory disturbances have declined dramatically since the start of the global financial crisis for example estimates using the laubach williams 2003 model indicate the natural rate in the united states fell to close to zero during the crisis and has remained there into 2016 explanations for this decline include shifts in demographics a slowdown in trend productivity growth and global factors affecting real interest rates this paper applies the laubach williams methodology to the united states and three other advanced economies canada the euro area and the united kingdom we find that large declines in trend gdp growth and natural rates of interest have occurred over the past 25 years in all four economies these country by country estimates are found to display a substantial amount of comovement over time suggesting an important role for global factors in shaping trend growth and natural rates of interest

are output fluctuations transitory according to the conventional view of the business cycle fluctuations in output represent temporary deviations from trend the purpose of this paper is to question this conventional view if fluctuations in output are dominated by temporary deviations from the natural rate of output then an unexpected change in output today should not substantially change one s forecast of output in say five or ten years our examination of quarterly postwar united states data leads us to be skeptical about this implication the data suggest that an unexpected change in real gnp of 1 percent should change one s forecast by over 1 percent over a long horizon

pay or pray the impact of charitable subsidies on religious attendance abstract the economic argument for subsidizing charitable giving relies on the positive externalities of charitable activities particularly from the religious institutions that are the largest recipients of giving but the net external effects of subsidies to religious giving will also depend on a potentially important indirect effect as well impacts on religious participation religious participation can be either a complement to or a substitute with the level of charitable giving understanding these spillover effects of charitable giving may be quite important given the existing observational literature that suggests that religiosity is a major determinant of well being among americans in this paper i investigate the impact of charitable subsidies on a measure of religious participation attendance at religious services i do so by using data over three decades from the general social survey as well as confirming the impact of such subsidies on religious giving using the consumer expenditure survey i find strong evidence that religious giving and religious attendance are substitutes larger subsidies to charitable giving lead to more religious giving but less religious attendance with an implied elasticity of attendance with respect to religious giving of as much as 1 1 these results have important implications for the debate over charitable subsidies they also serve to validate economic models of religious participation

optimal income taxation with endogenous participation and search unemployment we characterize optimal redistributive taxation when individuals are heterogeneous in their skills and their values of non market activities search matching frictions on the labor markets create unemployment wages labor demand and participation are endogenous average tax rates are increasing at the optimum this shifts wages below their laissez faire value and distorts labor demand upwards the marginal tax rate is positive at the top of the skill distribution even when the latter is bounded these results are analytically shown under a maximin objective when the elasticity of participation is decreasing in the skill level and are numerically confirmed under a more general objective under the maximin above approximately 20 000 per year our model recommends higher marginal tax rates than a comparable competitive setting

deep recessions fast recoveries and financial crises evidence from the american record do steep recoveries follow deep recessions does it matter if a credit crunch or banking panic accompanies the recession moreover does it matter if the recession is associated with a housing bust we look at the american historical experience in an attempt to answer these questions the answers depend on the definition of a financial crisis and on how much of the recovery is considered but in general recessions associated with financial crises are generally followed by rapid recoveries we find three exceptions to this pattern the recovery from the great contraction in the 1930s the recovery after the recession of the early 1990s and the present recovery the present recovery is strikingly more tepid than the 1990s one factor we consider that may explain some of the slowness of this recovery is the moribund nature of residential investment a variable that is usually a key predictor of recessions and recoveries

adam smith class labor and the industrial revolution abstract economists of virtually all schools of thought regard adam smith sympathetically this article explores adam smith s authoritarian side showing the close connection between smith s notion of appropriate behavior and the prevailing economic organization this article explores how this dimension of smith s pre analytic vision shaped his writings

trend breaks long run restrictions and contractionary technology improvements abstract structural vector autoregressions with long run restrictions are extraordinarily sensitive to low frequency correlations recent literature finds that the estimated effects of technology shocks are sensitive to how one treats hours per capita however after allowing for statistically and economically significant trend breaks in productivity results are much less sensitive hours fall when technology improves the issue is that the common high low high pattern of productivity growth and hours i e the low frequency correlation inevitably leads to a positive estimated response the trend breaks control for this correlation this example suggests a practical need for care in using long run restrictions

optimal income tax under the threat of migration by top income earners we examine how allowing individuals to emigrate to pay lower taxes changes the optimal nonlinear income tax scheme in a mirrleesian economy an individual emigrates if his domestic utility is less than his utility abroad net of migration costs utilities and costs both depending on productivity a simple formula that complements saez s formula obtained in closed economy is derived for the marginal tax rates faced by top income earners it depends on the labour elasticity the tax rate abroad and the migration costs expressed as a fraction of the utility obtained abroad the rawlsian marginal tax rates obtained for the whole population illustrate a curse of the middle skilled simulations are provided for the french economy

do recessions permanently change output abstract this paper examines whether negative innovations to gnp are more or less persistent than positive innovations we find that once we allow for the impulse response of gnp to be asymmetric negative innovations to gnp are observed to be much less persistent than positive ones in particular the effect of a recession on the forecast of output is found to be negligible after only eight to twelve quarters while the effect of a positive shock is estimated to be persistent and amplified over time our results may therefore help reconcile two antagonistic views about the nature of business cycle fluctuations

a concentration index for differentiated products the case of religious competition in the past scholars have used a herfindahl hirschman index using denominational market shares to measure the competitiveness of religious markets however this approach ignores both the imperfect substitutability between denominations and the degree of competition within denominations these two shortcomings make the current index a suspect measure of religious competition it often falsely identifies which market micro economists would generally consider the more competitive one we develop a new religious competition index that incorporates intra denominational competition and creates a substitutability parameter to better specify the appropriate degree of inter denominational competition while the model developed in this article applies specifically to religious markets our index of competition could be expanded to other economic markets where such a substitutability parameter is meaningful

a reexamination of the optimal nonlinear income tax abstract this paper investigates mirrlees model of optimal income taxation it provides a concrete example of utility and density functions for which the solution to the usual first order model is not implementable i e and example where the first order approach does not work adding second order conditions leads to an extended model and to implementable solutions if these conditions are binding one gets a kink in the optimal net income schedule and bunching of individuals occurs the properties of an optimal nonlinear income tax are reexamined within the extended model

voting over selfishly optimal nonlinear income tax schedules abstract majority voting over selfishly optimal nonlinear income tax schedules proposed by a continuum of individuals who have quasilinear in consumption preferences is considered roell 2012 has shown that individual preferences over these schedules are single peaked in this article a complete characterization of selfishly optimal schedules is provided each selfishly optimal schedule has a bunching region in a neighborhood of the proposer s skill type coincides with the maxi max schedule below this region and coincides with the maxi min schedule above it using techniques introduced by vincent and mason 1967 the bunching region is identified by solving an unconstrained optimization problem information about the optimal schedules is used to provide a relatively simple proof of single peakedness the condorcet winning tax schedule features marginal tax rates that are negative resp positive on the maxi max resp maxi min part of the schedule except at the endpoints of the skill distribution where they are zero

the information content of capacity utilization for detrending total factor productivity abstract in the production function approach an accurate output gap assessment requires a careful evaluation of the total factor productivity tfp cycle we build a common cycle model that links tfp to capacity utilization and we show that in almost all of the pre enlargement eu countries using information about capacity utilization reduces both the total estimation error and the revisions in real time estimates of the concurrent tfp cycle compared to a univariate decomposition we also argue that relaxing the constant drift hypothesis in favour of a non linear specification helps to offset a general tendency to underestimate the tfp cycle in the last decade

does religion matter in corporate decision making in america abstract we examine how corporate culture influences firm behavior prior research suggests a link between individual religiosity and risk aversion we find that this relationship also influences organizational behavior firms located in counties with higher levels of religiosity display lower degrees of risk exposure as measured by variances in equity returns or returns on assets they exhibit a lower investment rate and less growth but generate a more positive market reaction when they announce new investments finally chief executive officers are more likely to join a firm with a similar religious environment as in their previous firm when they switch employers

adam smith s analysis of joint stock companies we defend adam smith s theory of the firm from the standpoint of positive economics we argue that his evaluation of the joint stock firm was not moralistic but instead based on available empirical evidence the record showed that joint stock companies had a poor survivorship record even when granted legal monopoly status his analysis contained an explanation of the role of agency costs within the firm finally he did not discuss the east india company as an ordinary joint stock firm but rather as an aberrant form created by government

a complete solution to a class of principal agent problems with an application to the control of a self managed firm this paper considers a class of principal agent problems which have the following features 1 there is adverse selection because the principal ignores the value of one parameter of the agent s true characteristics 2 leaving aside the information parameter the principal s welfare as well as the agent s welfare depend on two types of variables observable to both of them the first ones possibly multidimensional are called action variable s and the second one which is one dimensional has in general the meaning of a money transfer 3 the principal is a stackelberg leader of the two person game he can commit himself to decision rules which are admissible on informational grounds he optimizes within the adequate class taking into account besides the agent s reaction one constraint which has generally the meaning of an individual rationality constraint and sometimes of a feasibility constraint the optimization is limited to the class of non stochastic mechanisms 4 the problem can also receive an alternative interpretation the principal faces a continuum of agents of unknown characteristics the distribution being known however stylized principal agent problems of this type have often been considered in the economic literature in particular the reader will later be able to recognize that the standard income tax model a la mirrlees 1971 the quality or quantity choice model of the monopolist a la mussa and rosen 1978 or maskin and riley 1982 and the model of government regulation of the private monopolist of baron and myerson 1982 all belong to

international evidence on time variation in trend labor productivity growth this paper provides international evidence on time variation in trend productivity growth based on the dataset for hours worked constructed by ohanian raffo 2012 applying both the endogenous break tests of bai perron 1998 2003 and the stock watson 1996 1998 tvp mub methodology substantial evidence of time variation in trend productivity growth is detected for most countries for either japan or countries belonging to the eurozone evidence points towards a significant growth decline over the last several decades weaker evidence is reported for the united states for which the 1990 s productivity acceleration is estimated to have been overall mild and of a temporary nature

rituals or good works social signaling in religious organizations we develop a model of social signaling of religiosity and cooperative behavior in religious organizations the model embeds a ritual based religious organization in which signaling arises through the use of costly rituals and a discipline based religious organization in which such signaling occurs through the monitoring of past behavior we use this framework to contrast positively and normatively these two forms of social signaling we show we develop a model of social signaling of religiosity and cooperative behavior in religious organizations the model embeds a ritual based religious organization in which signaling arises through the use of costly rituals and a discipline based religious organization in which such signaling occurs through the monitoring of past behavior we use this framework to contrast positively and normatively these two forms of social signaling we show that ritual based religions while using a costly and wasteful signal also imply a higher level of coordination of behavior in social interactions and a higher incidence of mutual cooperation our welfare analysis suggests that communities are more likely to support a switch to a discipline based religion if strategic complementarities are high and if there is sufficiently high level of public information about social behavior this accords with the success of calvin s reformation in switzerland and france a process characterized by the reduction of rituals along with the creation of institutions to monitor and publicize individuals behavior such as the consistory

the plucking model of business fluctuations revisited the recent surge of renewed interest in business cycles in general and real business cycles in particular brought to mind a plucking model of business fluctuations that i suggested some twenty five years ago but that has since sunk into complete oblivion 1 i was led to the model in the course of investigating the direction of influence between money and income did the common cyclical fluctuations in money and income reflect primarily the influence of money on income or of income on money one of the five kinds of evidence that i examined was the serial correlation of amplitudes of cycle phases 2 as i wrote is the magnitude of an expansion related systematically to the magnitude of the succeeding contraction does a boom tend on the average to be followed by a large contraction p 271 to find out i calculated rank difference correlations between measures of the amplitudes of expansions and successive contractions in three different series for the period 1879 to 1961 the three series were rate of change of the stock of money a physical index of general business and clearing debits as an indicator of dollar value change in general business similarly i asked the same question except starting with a contraction in the given series and correlating its amplitude with the amplitude of the succeeding expansion 3 the results were striking for all three series the correlation was trivial between the amplitude of an expansion and the amplitude of the succeeding contraction on the other hand for both the rate of change of the money stock and the physical index of general business the correlation was high and statistically significant between the amplitude of a contraction and the amplitude of the succeeding expansion for clearing debits this correlation too was low i concluded there appears to be no systematic connection between the size of an expansion and of the succeeding contraction whether size is measured by physical volume or by dollar value pp 272 73 on the other hand a large contraction in output tends to be followed on the average by a large business expansion a mild contraction by a mild expansion p 273 though that is not so for the dollar value of the expansion and contraction i went on this phenomenon if it should be confirmed by a fuller analysis of data for the united states and other countries would have important implications for the analysis of business cycles in general not solely for our monetary studies for one thing it would cast grave doubt on those theories that see as the source of a deep depression the excesses of the prior expansion the mises cycle theory is a clear example 4 for another it would raise serious questions about both the analytical models in terms of which most of us have come to approach the analysis of cycles and the statistical methods we use to analyze them our analytical models generally involve a conception of a self generating cycle in which each phase gives rise to the next and which may be kept going by a sequence of random shocks each giving rise to a series of damped perturbations the corresponding physical analogy is of an electrical network in which responses are described by sine waves the asymmetric serial correlation patter suggests that this analogy may be misleading that a better one is what can be termed a plucking model consider an elastic string stretched taut between two points on the underside of a rigid horizontal board and glued lightly to the board let the string be plucked at a number of points chosen more or less at random with a force that varies at random and then held down at the lowest point reached the result will be to produce a succession of apparent cycles in the string whose amplitudes depend on the force used in plucking the string the cycles are symmetrical about their troughs each contraction is of the same amplitude as the succeeding expansion

does the new economy measure up to the great inventions of the past abstract during the four years 1995 99 u s productivity growth experienced a strong revival and achieved growth rates exceeding that of the golden age of 1913 72 accordingly many observers have declared the new economy to be an industrial revolution even more important than the second industrial revolution of 1860 1900 which made the golden age of productivity growth possible this paper dissects the recent productivity revival subtracts out a cyclical component and concludes that there is no revival of the productivity growth trend in the 88 percent of the private economy lying outside of the durables manufacturing sector the paper explains this surprising finding by pointing to limitations in computers and the internet in comparison with the great inventions of the past

the recent boom bust cycle the relative contribution of capital flows credit supply and asset bubbles abstract we use an estimated open economy dsge model with financial frictions for the us and the rest of the world to evaluate various competing explanations about the recent boom bust cycle we find that the savings glut hypothesis is insufficient for explaining all aspects of the boom in the us relatively strong tfp growth and expansionary monetary policy are also not able to explain fully the volatility of corporate and in particular residential investment we identify bubbles in the stock and housing market as crucial concerning the downturn in 2008 2009 the fall in house prices and residential investment only plays a minor role mortgage defaults have more explanatory power especially in a specification of the model with a segregated equity market finally the bursting of the stock market bubble was at least as important in this recession as in 2001 because of various negative shocks hitting the economy at the same time in 2008 2009 and continued positive technology growth not only the real interest rate declined but inflation fell rapidly and left insufficient room for monetary policy to play a similar stabilising role as in previous recessions

introduction to the economics of religion after a very long hiatus economists have begun again to study the relationship between economics and religion this article seeks to summarize and evaluate the principal themes and empirical findings that have appeared in some 200 recent papers on the economics of religion although some of the research concerns the economic consequences of religiosity most applies standard economic theory to the study of individual religious activity the characteristics of religious groups and the impact of regulation and competition on religious markets

stochastic growth in the united states and euro area this paper estimates using data from the united states and the euro area a two country stochastic growth model in which both neutral and investment specific technology shocks are nonstationary but cointegrated across economies the results point to large and persistent swings in productivity both favorable and adverse originating in the united states but not transmitted to the euro area more specifically the results suggest that while the euro area missed out on the period of rapid investment specific technological change enjoyed in the united states during the 1990s it also escaped the stagnation in neutral technological progress that plagued the united states in the 1970s

inherent inequality and the optimal graduation of marginal tax rates in most countries marginal tax rates increase with income this is at variance with the results of the optimal income taxation literature whose numerical calculations have established the presumption that optimal marginal tax rates should decline with income have the existing results of optimal income tax literature therefore established a presumption that the observed pattern is suboptimal the object of this paper is to attempt to answer this question the numerical calculations that followed mirrlees s 1971 pioneering contribution tried many variations on his basic parametrisation including different preference structures and different functional forms however so far as we are aware most of the reported results maintain his basic assumption of a log normal distribution of abilities or wages with a standard deviation of logs of 0 39 mirrlees 1971 himself appealed the work of lydall 1969 for this figure but it has become the industry standard we show in this paper that departures from this assumption in particular increases in inherent inequality can alter the qualitative pattern of optimal marginal tax rates dramatically contrary to the currently available calculations we show that the optimal graduation can indeed be such that marginal tax rates increase for the majority of the population which is consistent with the observed pattern but that there continues to exist a significant income range at the top where marginal tax rates decline which of course is counter to the observed pattern

the elasticity of taxable income evidence and implications abstract a central tax policy parameter that has recently received much attention but about which there is substantial uncertainty is the overall elasticity of taxable income we provide new estimates of this elasticity which address identification problems with previous work by exploiting a long panel of tax returns to study a series of tax reforms throughout the 1980s this identification strategy also allows us to provide new evidence on both the income effects of tax changes on taxable income and on variation in the elasticity of taxable income by income group we find that the overall elasticity of taxable income is approximately 0 4 the elasticity of real income not including tax preferences is much lower we estimate small income effects of tax changes on reported income implying that the compensated and uncompensated elasticities of taxable income are very similar we estimate that this overall elasticity is primarily due to a very elastic response of taxable income for taxpayers who have incomes above 100 000 per year who have an elasticity of 0 57 while for those with incomes below 100 000 per year the elasticity is less than one third as large moreover high income taxpayers who itemize are particularly responsive to taxation our estimates suggest that optimal tax structures may feature tightly targeted transfers to lower income taxpayers and a flat or even declining marginal rate structure for middle and high income taxpayers

church attendance in great britain an ordered logit approach the church attendance decision of individual economic agents is analysed within a becker style allocation of time framework using an ordered logit model with data derived from the british household panel study bhps separate attendance equations are estimated for males and females the empirical results in line with previous north american studies suggest that labour income variables do account for some of the variation in attendance in addition attendance is found to be correlated with factors such as denominational affiliation educational attainment and intensity of belief

long run implications of investment specific technological change an attempt is made to disentangle its effects from the more traditional hicksneutral form of technological progress the balanced growth path for the model is characterized and calibrated to u s national income and product account nipa data the quantitative analysis suggests that investment specific technological change accounts for the major part of growth jel e13 030 041 047

hours per capita and productivity evidence from correlated unobserved components models recent studies debate the effect of a permanent productivity shock on hours per capita within a structural var context this paper examines the issue using a correlated unobserved components uc framework the estimates show that permanent shocks to productivity are negatively correlated with transitory shocks to hours this result is robust for non stationary or levels stationary specifications of hours model comparisons indicate that the data do not favor imposing var type restrictions on the uc models copyright 2008 john wiley sons ltd

nonlinearity and the permanent effects of recessions this paper presents a new nonlinear time series model that captures a post recession bounce back in the level of aggregate output while a number of studies have examined this type of business cycle asymmetry using recession based dummy variables and threshold models we relate the bounce back effect to an endogenously estimated unobservable markov switching state variable when the model is applied to us real gdp we find that the markov switching regimes are closely related to nber dated recessions and expansions also the markov switching form of nonlinearity is statistically significant and the bounce back effect is large implying that the permanent effects of recessions are small meanwhile having accounted for the bounce back effect we find little or no remaining serial correlation in the data suggesting that our model is sufficient to capture the defining features of us business cycle dynamics when the model is applied to other countries we find larger permanent effects of recessions copyright 2005 john wiley sons ltd

religious market competition in a richer world economic growth has not led to a decline in religion despite past predictions that it would using a formal model of religious competition i show how economic growth produces counteracting effects on religious activity in an open religious market and that it has little effect in a religious market that is already secularized due to regulations that prohibit religious competition or in a highly religious market with regulations that inhibit secular activities theories predicting the decline of religion due to rising opportunity costs of religious demand and supply ignore countervailing influences t he opinion is everywhere gaining ground that religion is a mere survival from a primitive age and its extinction only a matter of time crawley 1905 i think what i and most other sociologists of religion wrote in the 1960s about secularization was a mistake our understanding was that secularization and modernity go hand in hand it wasn t a crazy theory there was some evidence for it but i think it s basically wrong most of the world today is certainly not secular it s very religious berger 1997 1

macroeconomic forecasting using diffusion indexes this article studies forecasting a macroeconomic time series variable using a large number of predictors the predictors are summarized using a small number of indexes constructed by principal component analysis an approximate dynamic factor model serves as the statistical framework for the estimation of the indexes and construction of the forecasts the method is used to construct 6 12 and 24 monthahead forecasts for eight monthly u s macroeconomic time series using 215 predictors in simulated real time from 1970 through 1998 during this sample period these new forecasts outperformed univariate autoregressions small vector autoregressions and leading indicator models

religion and economic performance summary this paper investigates the relationship between religion and economic performance in both cross country and within country regressions the null hypothesis that religious affiliation is uncorrelated with performance can frequently be rejected i e religion matters though the regressions do not yield a robust pattern of coefficients with respect to particular religions the results with respect to islam do not support the notion that it is inimical to growth on the contrary virtually every statistically significant coefficient on muslim population shares reported in this paper in both cross country and within country statistical analyses is positive if anything islam promotes growth
