the public choice of superior sanctions this paper analyzes the public choice of specific forms of sanctions current sanctions are essentially quantity constraints q sanctions which are like quotas in that they might bestow benefits on certain special interest groups in the target country revenue sanctions r sanctions may be able to recapture such benefits in the form of sender government revenue which could either compensate for the costs of sanctions to the sending country or finance other sanction enhancing activities aimed at the target country hence r sanctions may be superior to q sanctions in general or on the basis of target efficiency however public choice analysis suggests that q sanctions will generally be chosen over r sanctions by democratic countries

adaptation and distress in the urban economy a study of kampala households abstract though uganda underwent fairly rapid economic growth after independence in 1962 the civil strife and external shocks of the 1970s and 1980s led to rapid decline the impacts on kampala households reflect in many ways those on the rest of the country and have led to extensive diversification of incomes mainly to reduce the risks perceived in today s unstable environment a decrease in the share of wages in total incomes compensated by allowances of various types increased engagement in informal sector activities and even farming in the urban sector the main tasks of economic management are twofold to stabilize wage employment and to ameliorate the social misery caused by the decline the limited resource base and the continued external disturbances make the prospects for sustained recovery precarious

allocation of individuals to job levels under rationing summary we augment an ordered response model for the job level at which individuals desire to work with allowance for individual reporting of a discrepancy between actual and desired job level and we also investigate possible biases from restricting the observations to the employed and omitting the unemployed we find that the latter bias can be ignored and interpret this as evidence that the unemployed are not choosier than the employed people claiming inadequate capability utilization are not markedly differently allocated than those claiming a proper match women s lower job levels cannot be explained from rationing by capability utilization

on optimal production and the market to book ratio given limited shareholder diversification our purpose is to examine a firm s optimal output decision and valuation when its shareholders hold a limited number of risky assets the primary theoretical result indicates that the market to book ratio is a function of the degree of shareholder diversification our theory suggests a negative relationship between a firm s market to book ratio and shareholder diversification

labour supply in italy an empirical analysis of joint household decisions with taxes and quantity constraints this study applies an econometric framework which allows for complex non convex budget sets highly non linear labour supply curves and imperfect markets with institutional constraints a married couple s version of the model is estimated on italian microdata the empirical results show that male labour supply is rather inelastic while labour supply among females especially participation is considerably more elastic the elasticities depend strongly on household income the largest elasticities are found for females living in poor households the results of the tax simulations suggest that there are only modest labour supply responses from replacing the 1987 system by proportional taxes copyright 1999 john wiley sons ltd

the endogenous public choice theorist public choice theory has effectively explored defects in collective action and political processes however little attention has been given to the fact that any recommendations as to how to improve the situation can only be realized on the basis of precisely those defective institutions what turns up here can be identified as a problem of self reference normative contributions by buchanan and hayek may serve as an example in order to clear up the seemingly paradoxical situation endogenization of the public choice theorist within an extended theory is suggested a straight forward extension is briefly outlined

the labour supply unemployment and participation of lone mothers in in work transfer programmes in work transfer schemes have recently been suggested as a device for encouraging labour force participation and reducing the severity of the disincentives associated with out of work income support schemes here we estimate a discrete choice labour supply model which allows for endogenous in work welfare programme participation we also allow for involuntary unemployment so as to distinguish between programme non participation and an inability to obtain work and thereby generate an eligibility to the programme

unemployment and female labour supply the definition of labour force participation in the standard labour supply model stands in sharp contrast to that used in compiling the labour force statistics in the labour supply models only those supplying positive hours of work are considered to be labour force participants on the other hand participation in the labour force statistics is often defined to include not only those supplying positive hours but also those actively searching for work this paper is an attempt to reconcile these concepts by allowing unemployed workers to enter a generalisation of the standard labour supply model this turns out to be a convenient way to enter demand side factors directly into the determination of an individual s labour market position the model is applied with some success to the working behaviour of married women in the uk family expenditure survey

job search hours restrictions and desired hours of work a structural empirical job search model is presented that incorporates the labor supply decision of individuals the arrival of a job offer is modeled as a random draw from a wage hours offer distribution subjective information is used on desired working hours to identify optimal hours from offered hours policy simulations are performed to address several policy questions does a decrease in unemployment benefits lead to the acceptance of jobs with less preferred working hours how does a decrease in the length of the standard working week affect the job acceptance behavior of the unemployed

a life cycle consistent empirical model of family labour supply using cross section data this paper estimates a utility maximising model of the joint determination of male and female labour supplies using a sample of married couples from the u k family expenditure survey the emphasis is on the estimation of within period preferences that are consistent with intertemporal two stage budgeting under uncertainty however the approach we adopt provides an alternative method of estimating certain aspects of life cycle behaviour to the fixed effects constant approach of heckman and macurdy 1980 macurdy 1981 and browning deaton and irish 1985 moreover it relaxes some of the underlying restrictions that are implicit in these constant models under uncertainty

can sustainable consumption be learned a model of cultural evolution abstract this paper shows how sustainable consumption patterns can spread within a population via processes of social learning even though a strong individual learning bias may favor environmentally harmful products we present a model depicting how the biased transmission of different behaviors via individual and social learning influences agents consumption behavior the underlying learning biases can be traced back to evolved cognitive dispositions challenging the vision of a permanent transition toward sustainability we argue that green consumption patterns are not self reinforcing and cannot be locked in permanently

political decentralization and corruption evidence from around the world abstract how does political decentralization affect the frequency and costliness of bribe extraction by corrupt officials previous empirical studies using subjective indexes of perceived corruption and mostly fiscal indicators of decentralization have suggested conflicting conclusions in search of more precise findings we combine and explore two new data sources an original cross national data set on particular types of decentralization and the results of a firm level survey conducted in 80 countries about firms concrete experiences with bribery in countries with a larger number of government or administrative tiers and given local revenues a larger number of local public employees reported bribery was more frequent when local or central governments received a larger share of gdp in revenue bribery was less frequent overall the results suggest the danger of uncoordinated rent seeking as government structures become more complex

limits to institutional reforms the essay draws on the theory of macro economic policy as it has evolved to discuss implicit policy determinism in the new economics of institutions the extension of rational choice methods to new levels of analysis such as micropolitics macropolitics political macroeconomics and microfoundations of cooperation has apparently reduced the policy choice set and diminished the role of experts all outcomes reflect constrained maximization by rational agents the essay argues however that scarcity of knowledge leads to incomplete and variable policy models and that competition among policy models creates a role for experts in social change

consumer behaviour theory and empirical evidence a survey this survey is designed to emphasize the relationship between empirical a nd theoretical considerations in the analysis of consumer behavior a lthough it focuses primarily on analysis at the individual or micro l evel it tries where possible to draw implications for the estimati on of aggregate relationships the importance of micro level analysis stems from the rapid expansion in available panel and survey data se ts this development has generated its own theoretical and empirical issues many of which are raised in this survey copyright 1988 by royal economic society

can a low carbon energy transition be sustained in post fukushima japan assessing the varying impacts of exogenous shocks abstract in the aftermath of the fukushima nuclear crisis japan began contemplating energy policy reforms that drew inspiration from low carbon research this article focuses on a question central to advancing low carbon research in japan and elsewhere namely how does an exogenous shock affect the onset magnitude and permanence of changes in electricity consumption the article employs intervention analysis with an autoregressive moving average arma model to answer this question the data analysis reveals that post fukushima electricity use underwent a sudden significant and sustained reduction across japan the shock not only affected the tokyo electric power company tepco coverage area but the more distant kansai electric power company kepco coverage area large electricity users responded with an immediate and significant reduction in electricity consumption that rebounded to below pre crisis levels households responded more gradually with no rebound two of the more interesting results from the data analysis the persistence in reductions in the more distant kepco coverage area and the rebound among large users are then explained with a review of survey data and policy trends overall the quantitative and qualitative evidence suggests that an exogenous shock may give rise to a reduction in electricity consumption but cannot sustain a low carbon transition

systematic risk and the theory of wage indexation in this article the author integrates the theory of optimal wage indexation with capital market theory the optimal indexation factor in his model depends on workers preferences firm specific variables and economywide capital market variables a major difference between the results of the model and those of the previous literature is that in his model nonsymmetric randomness does not affect the indexation decision in addition the effects of economywide capital market variables can provide an explanation for why the author does not observe wage contracts with more than perfect indexation contracts where real wages rise with unexpected inflation copyright 1990 by the university of chicago

simultaneously modeling the supply of weeks and hours of work among female household heads this paper explores the differential nature of labor supply decisions regarding weeks of work per year and hours of work per week among female household heads a model of labor supply that separates the weeks hours decision is presented and estimated allowing for simultaneity in the weeks hours decision as well as for the presence of either fixed costs or weeks and hours constraints the results indicate that not only are weeks and hours decisions separate from the labormarket participation decision but they are also quite different from each other although they appear to be simultaneously determined

married women s hours and participation revisited elasticity estimates are presented for participation and hours of work for a sample of married women in the social change and economic life initiative sceli 1986 data set a logit model is used to estimate the participation function and a tobit model is employed to estimate an hours of work equation the results are in agreement with the evidence available for the uk the own wage hours of work elasticity is found to be relatively elastic with negligible effects detected for non labour income and the husband or spouse s wage the effects on participation of an unemployed husband or spouse were examined and found to have a strong negative effect

benefits and the labour supply of women married to unemployed men this paper seeks to explain the low labor force participation rates of women married to unemployed men in the reducing the net increment to household income that would result from the wife s employment simple probit models of the participation and part time full time decisions are estimated using a large cross sectional data set the results confirm the importance of severe disincentive effects controlling for labor market conditions income related benefits are found to create worse problems than national insurance benefits both types impede part time work in particular copyright 1990 by royal economic society

labour supply search and taxes abstract classical labour supply theory is one of the most sophisticated parts of labour economics yet there is no compelling theoretical reason to believe in an outcome on a classical labour supply curve and it is unclear whether it is a good empirical description of the way in which labour markets actually work this paper uses the techniques of search theory to analyse the impact of changes in the tax system on incentives to work when individuals do not have flexibility of hours within jobs it is shown how the traditional comparative statics are of some use but are rarely the whole story and some comparative statics results are surprising

technological diffusion and preference learning in the world of homo sustinens the challenges for politics abstract this article relates agents learning of a preference for a technology competition of technologies and their relative diffusion among potential adopters competitive interactions between two technologies are captured by an extended lotka volterra model to also incorporate preference learning on the part of potential adopters of these technologies we combine it with a model of cultural learning based on role model conformist and hedonistic learning our theoretical analysis is illustrated by a concrete example the competition between electric mobility and conventional forms of individual mobility the model enables an evaluation of specific policy instruments as to the promotion of sustainable technology

the sensitivity of an empirical model of married women s hours of work to economic and statistical assumptions this study undertakes a systematic analysis of several theoretic and statistical assumption s used in many empirical models of female labor supply using a singl e data set psid 1975 labor supply data the author is able to replic ate most of the range of estimated income and substitution effects fo und in previous studies in this field he undertakes extensive specif ication tests and finds that most of this range should be rejected du e to statistical and model misspecifications the two most important assumptions appear to be the tobit assumption used to control for sel f selection into the labor force and exogeneity assumptions on the wi fe s wage rate and her labor market experience copyright 1987 by the econometric society

labour supply incentives and the taxation of family income taxing family income richard blundell and ian walker will lower marginal rates of income tax increase incentives to work the traditional theoretical argument ignores the fact that many individuals are members of households with more than one potential participant in paid employment the theory of optimal income tax is utilized to argue that the tax system should discriminate between individuals in the same household if their labour supply responses are different empirically the response of labour supply to changes in after tax wages is largest for secondary workers particularly married women hence the largest beneficial incentive effect is obtained if such individuals face lower tax rates since these individuals typically have below average pre tax earnings this suggests a simple way to implement our proposal establish a progressive income tax with individual earnings as the basis of assessment this might have additional advantages of fairness but its primary purpose would be to ensure that low earning but highly responsive individuals face low marginal tax rates while high earning but relatively unresponsive individuals face higher marginal tax rates contrary to popular wisdom a flat rate tax system would be less favourable for work incentives we illustrate this theoretical argument using an empirical model of labour supply embedded in a micro computer programme capable of simulating alternative tax systems

lock in vs critical masses industrial change under network externalities abstract where increasing returns to adoption play a role in the diffusion of a new technology technological lock in is now often claimed to occur however this result and the modeling approach that produces it are problematic further innovations could never have a chance of disseminating if lock in had occurred in the diffusion process of earlier innovations yet in reality industrial change does not come to a halt the paper offers a discussion of the apparent paradox from an alternative modeling approach conditions are derived under which a newly introduced technology can successfully disseminate in the market despite existing network externalities

union firm bargaining and the influence of product market power and production technology on systematic risk the relationship between the capm firm beta and the firm s microeconomic decisions is studied by a model under uncertainty which combines the feature of an ex ante inputs substituable production technology and the existence of a union which bargains over various economic dimensions of the firm it is shown that the earlier findings of a relationship between the firm beta the firm product market power and the labor capital ratio may be reinforced through the indirect channel of labor market bargaining but the relationship becomes more complex and heavily depends on the scope of the union firm bargaining process this yields the empirical prediction confirmed for a panel of belgian firms that any proper estimation of the determinants of firm beta must control for firms in the sample being unionized

off farm labour allocation decisions in small scale rural households in zimbabwe the double hurdle model is used to analyse the off farm labour decisions of small scale agricultural household members in the shamva district of zimbabwe the approach permits the joint modelling of the decision to participate in the labour market and the decision regarding the amount of time allocated to work results indicate that a number of variables notably gender education and assets indeed have effects which are qualitatively and quantitatively different in terms of participation and hours worked overall the empirical analysis confirms the importance of individual characteristics such as gender and education and household farm characteristics e g land area accessible to the household productive assets remittances and the agricultural terms of trade in influencing the labour market decisions of rural household members

a model of female labour supply in which supply is dependent upon the chances of finding a job in this paper we extend a model of female labour supply by considering the impact of the local labour market thus in our model a woman supplies her labour if she has both made the decision to participate and found a job this extension is of particular importance in times of high unemployment when discouraged worker effects will be at their strongest we also consider the contribution of such a model to the debate concerning the labour supply of women married to men who are unemployed

a regional analysis of labour force participation rates across the member states of the european union elhorst j p 1996 a regional analysis of labour force participation rates across the member states of the european union reg studies 30 455 465 this study investigates the causes of variation in labour force participation rates in a regional europe two participation rate equations are estimated one for men and one for women using annual data derived from eurostat 1983 1989 the explanatory variables are based on previous studies on the subject of the neoclassical formulation of the individual s labour supply function extended by the situation in which an individual who wishes to work cannot find a job and becomes involuntarily unemployed the consistency of the parameter estimates to different estimation models is investigated it turns out that heterogeneity between the member states of the eu is so important that it is almost impossible to find an overall regression equation for the whole eu elhorst j p 1996 une analyse regionale des taux d activite dans les pays membres de l union europ

going onto invalidity benefit a study for women 1977 78 1983 84 the main form of state insurance for long term sickness in britain is invalidity benefit there has been a dramatic growth in the stock of claimants on this benefit since its introduction in 1971 a logit model is fitted to explain at the individual level the probability of entering invalidity benefit among over 50 000 women in 1977 8 and over 65 000 in 1983 4 demographic characteristics played a powerful role in this model pay and benefit rates were also significant married women s entry probabilities were highly sensitive to local labour market conditions and much more so than other population groups

testing intertemporal substitution implicit contracts and hours restriction models of the labor market using micro data we present new tests of three theories of the labor market intertemporal substitution hours restrictions and implicit contracts the intertemporal substitution test we implement is an exclusion test robust to many specification errors and we consistently reject this model we model hours restrictions as part of an endogenous switching model we compare the implicit probit equation to an unrestricted probit equation for unemployment and reject the hours restriction model for the implicit contracts model we estimate non separable within period labor supply and consumption equations we test a cross equation restriction of the model and cannot reject the implicit contracts model jel e30 j22 j60

selection criteria for a microeconometric model of labour supply the wide variety of observed behaviour that is displayed in survey data suggests that microeconometric models should allow a reasonable degree of flexibility in specification however since these models are generally used for policy analysis they are required to satisfy some degree of theoretical consistency this requirement has generally led to the adoption of rather simple inflexible models based on additive preferences or linear labour supply responses we estimate and test a sequence of models for the labour supply of married working women emphasizing the importance of testing both the thecretical and statistical assumptions underlying the models

statistical models for zero expenditures in household budgets household budget surveys are an important source of data on consumer s expenditure not just for individual consumers but also for estimating national aggregates however it is a widespread finding that for certain commodities most notably tobacco and alcohol the estimate from the household survey falls short of the known consumption total calculated with some confidence from data on production imports exports and excise duties for example in the british family expenditure survey with which we shall largely be concerned total tobacco expenditure was underestimated in 1976 by 21 percent see kemsley redpath and holmes 1980 p 51 much of this understatement together with that on alcohol is thought to occur because of the design of the survey which excludes many persons amongst whom consumption of such items is thought to be atypically high e g prisoners hoteliers and their residents merchant seamen even so the possibility remains that some of the understatement is due to various types of misreporting by households included in the survey in this paper we consider a model in which the standard tobit specification tobin 1958 is supplemented by the operation of a simple binary censor the tobit model is essentially a linear regression model in which non positive observations of the dependent variable are replaced by zero we take this specification as our starting point but add a second censoring process that randomly replaces a fraction of the observations generated by the tobit model bv zeroes the combined model can serve as a representation of several types of

reviving leviathan fiscal federalism and the growth of government this article revisits the influential leviathan hypothesis which pos its that tax competition limits the growth of government spending in decentralized countries i use panel data to examine the effect of fiscal decentralization over time within countries attempting to distinguish between decentralization that is funded by intergovernmental transfers and local taxation first i explore the logic whereby decentralization should restrict government spending if state and local governments have wide ranging authority to set the tax base and rate especially on mobile assets in countries where this is most clearly the case decentralization is associated with smaller government second consistent with theoretical arguments drawn from wel fare economics and positive political economy i show that governments grow faster as they fund a greater portion of public expenditures through intergovernmental transfers

rural electrification and household labor supply evidence from nigeria in nigeria the most populated african country rural electrification is a critical issue because of the low household electrification rate and the poor quality of the grid this energy poverty has harmful economic and social consequences in rural areas such as low productivity lack of income generating opportunities and poor housing conditions in this paper we consider electrification as a technical shock that may affect household time allocation using the 2010 2011 general household survey we investigate how electrification affects female and male labor supply decisions within rural households in nigeria focusing on husband wife data we consider potential dependence in spouses labor supply decisions and address the challenge of zero hours of work using a recent copula based bivariate hurdle model deb et al 2013 in addition an instrumental variable strategy helps identify the causal effect of elec trification our results underline that this dependence in spouses labor supply decisions is critical to consider when assessing the impact of electrification on these outcomes electrifi cation increases the working time of both spouses in the separate assessments but the joint analysis emphasizes only a positive effect of electrification on husbands working time in line with the household labor supply approach our findings highlight that within the household the labor supply decisions of one spouse significantly affect those of the other spouse thus if we neglect the effect of electrification on the spouse of the individual examined we may fail to assess how this individual has been actually affected by this common shock on both spouses our results suggest that these within household relationships promote husbands working time at the expense of wives working time

social interactions and habit formation in a model of female labour supply this paper investigates the influence of habit formation and preference interdependence on labour supply behaviour of married females a novelty of the paper is that we incorporate direct survey information on reference groups of individuals in a neoclassical labour supply model for that purpose we first estimate a latent variables model relating the direct information to the true but unobserved reference groups one of the most interesting features of the model is that the presence of young children becomes an insignificant factor in the hours equation while it remains a significant factor in the participation decision in addition the labour supply curve is much flatter in a model with habit formation and preference interdependence than in a model without it both habit formation and preference interdependence contribute significantly to the explanation of female labour supply 1998 elsevier science s a all rights reserved

discrimination under imperfect competition a way of earning or wasting money abstract how would firms allocate their employees between two differently paid jobs suppose that a number of equally skilled workers belonging to two distinguishable groups are competent enough for both positions it is then profitable to employ the group with the higher labour supply elasticity in the high wage occupation this explains why less wealthy groups are discriminated against but it suggests that discrimination of women may be a waste from the standpoint of the employer in an important category of cases

a double hurdle model of cigarette consumption this paper shows the importance of the double hurdle approach for modelling individuals cigarette consumption using data from the uk general household survey and argues that participation and consumption should be treated as separate individual choices the likelihood function for the full double hurdle is derived and it is shown how restrictions on the stochastic specification of the model and auxillary information which identifies ex smokers allow it to be decomposed the empirical results highlight the value of the sample separation information and the need to model starting and quitting as separate decisions

municipal annexation and local monopoly power we have found that the fiscal power of a city can be increased by extension of its borders within a land area that is homogeneous with respect to earning opportunities even when numerous rival jurisdictions exist in the area we hypothesized that extending municipal boundaries will have a positive effect on discretionary outlays and on expenditures per capita the evidence presented supports these hypotheses furthermore municipal wages appear to be significantly increased in cities experiencing annexation growth therefore we would expect to find that municipal employees are more inclined to favor annexation than the rest of the electorate from a policy standpoint this study suggests that significant perverse effects on fiscal efficiency may follow adoption of legal reforms that facilitate the ability of municipalities to extend their borders or that restrict the formation of new municipalities

contractarian political economy and constitutional interpretation at the meetings in 1974 i presented a paper entitled a contractarian paradigm for applying economic theory printed 1975 in that paper along with others see my 1979 book i argued that our subject matter is centrally a science of exchange or a science of contract and that the exchange paradigm should take precedence over the maximizing paradigm this shift in the focus of positive inquiry carries normative implications conceptions such as aggregate efficiency in the allocation of resources become at best examples of functionalist error along with the more explicitly normative variants of the social welfare function the contractarian or catallactic approach to economic interaction suggests that systems or subsystems be evaluated in terms of the comparative ease or facility with which voluntary exchanges contracts or trades may be arranged between and among members of the community normative judgments take the form of statements that array better and worse processes rules laws institutions within which exchanges are allowed to take place these judgments are categorically distinct from those that array and evaluate results or outcomes this shift in normative political economy has implications for the issues of constitutional interpretation debated by legal scholars and philosophers these issues involve disputes along several related and intersecting dimensions between judicial activism and nonactivism between judicial deference to legislative authority and judicial independence between strict constructivism and pragmatism between original intent and legal environmentalism between teleological and deontological conceptions of law my purpose here is to discuss some of these contractarian implications for constitutional interpretation this is a limited purpose and i advance no direct and extended argument on either general philosophical issues or on points of debate in particular legal settings any identifiable contribution of the contractarian political economist must emerge from the differentially abstracted order that his perspective imposes on social reality section i covers the familiar distinction between an individualistic and a communitarian starting point the implication for legal interpretation of constitutional rules is almost self evident in section ii i again go over analysis developed elsewhere that extends the catallactic paradigm from the economy to the political order and in particular to the design selection and enforcement of constitutional rules section iii examines the implications for judicial interpretation of the political constitution and in particular the implications for the debate between strict constructivism and pragmatism and between original intent and legal environmentalism in section iv the argument is extended to the contractarian s stance in interpretative confrontation with rules that cannot find a logic in any contractarian ideal

female participation and male unemployment duration in greece evidence from the labour force survey the work reported in this paper is part of a project financed by the centre for planning and economic research kepe athens we should like to thank kepe s scientific director louka katseli for her help and encouragement and the staff of kepe for their help with the data we should like to thank d karantinos for the insights he provided on the greek labour market finally we should like to thank neils westergaard nielsen for his comments all errors and shortcomings remain our responsibility

estimation of a labour supply model with censoring due to unemployment and underemployment this study proposes and implements a method of labour supply estimation which is appropriate when the sample contains unemployed and underemployed workers the estimation method consists of excluding unemployed and underemployed workers from the sample and then using to avoid selection bias an extension of heckman s approach to the case where two correlated selection rules generate the sample hausman s specification test is then used to determine whether ignoring constrained workers has led to biases in traditional labour supply estimates and the empirical results suggest that previous estimates of several important parameters are biased since the biases go in the direction that would be predicted by the hypothesis that the unemployed and underemployed are constrained the results support this hypothesis

work incentives and in work benefit reforms a review in work benefit reforms seek to reduce poverty and promote employment among low income families using evidence from similar policies in the usa and canada this paper reviews the likely impact of recent uk reforms the focus is on employment and hours in particular the paper examines the effectiveness of the new working families tax credit in the uk in increasing employment among low income families it presents evidence suggesting modest increases in employment for single parents and workerless married couples with children but with some offsetting reductions in employment in two earner couples with young children

buchanan on externalities an exercise in applied subjectivism abstract buchanan s work on the methodology of economics includes many references to externalities buchanan has emphasized that a subjective conception of economics and a focus put on exchange rather than on choice has implications on an analysis of externalities in this paper we analyze the reverse claim buchanan s views on externalities are a perfect illustration of his plea for subjectivism in economics and the need to focus on economics as a science of exchange we show that buchanan s treatment of externalities was a laboratory for his claims and arguments about subjectivism

a model of female labour supply in the presence of hours restrictions abstract we develop a discrete choice model of female labour supply in finland using a data set constructed by merging the 1980 labour force survey and housing and population census this contains observations on the perceived incidence of constraints in the labour market and allows us to identify the effects of such constraints on observed labour supply approximately one in five women appears to be seriously constrained in her choice of hours of work our estimated model implies that the response of labour supply to variation in tax and wage rates is rather small

endogeneity and sample selection in a model for remittances abstract we estimate a remittance model in which we address endogeneity and reverse causality relationships between immigrants remittances pre transfer income and consumption in order to take into account the fact that a large share of individuals do not remit instrumental variable variants of the double hurdle and heckit selection models are proposed and estimated by limited information ml semiparametric extensions are considered as robustness checks our results for a sample of recent immigrants to australia show that endogeneity is substantial and that estimates obtained by the methods previously employed in the literature may be misleading if given a behavioral interpretation

testing whether unemployment represents intertemporal labour supply behaviour in the lucas rapping 1969 model of the labour market fluctuations in unemployment represent individuals optimally adjusting their labour supply behaviour in response to fluctuations in wage rates over the business cycle in this paper i propose and implement a misspecification test of the lucas rapping treatment of unemployment as labour supply behaviour using panel data this test extends previous such work with micro data by simultaneously allowing for intertemporal substitution uncertainty and endogenous unemployment using the standard specification of intertemporal labour supply behaviour i find strong evidence against this interpretation of unemployment there are two possible interpretations of the test results the first is that it is necessary to turn to alternative models of the labour market in which unemployed workers are off a supply function the second is that the test results indicate the necessity of moving to more complex models of intertemporal substitution however given current econometric techniques and data sets these alternative models of intertemporal substitution will be extremely difficult to test

testing the predictive value of subjective labour supply data empirical implementation of labour supply theories is usually based on realized labour market behaviour this requires strong assumptions about the impact of labour demand a possibility to avoid these assumptions is to make use of subjective data on desired labour supply in this paper we investigate whether respondents answers to survey questions on the desired number of working hours contain additional information on the preferences of the individuals using panel data for the netherlands we analyze whether deviations between desired hours and actual hours of work help to predict future job changes or changes in hours worked we use parametric and recently developed nonparametric tests the results suggest that subjective information on desired working hours are helpful in explaining female labour supply for males the evidence is mixed

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

political economy of mechanisms we study the optimal mirrlees taxation problem in a dynamic economy in contrast to the standard approach where the taxation mechanism is operated by a benevolent planner with full commitment power we focus on economies in which policy decisions are made by self interested politicians who cannot commit to policies the society controls politicians using elections we show that the provision of incentives to politicians can be partly separated from redistribution across agents and that political economy constraints can be modeled as introducing additional aggregate distortions in the dynamic mirrlees problem we provide conditions under which the political economy distortions persist or disappear in the long run if the politicians are as patient as the agents the best sustainable mechanism leads to an asymptotic allocation where the aggregate distortions arising from political economy disappear in contrast when politicians are less patient than the citizens positive aggregate labor and capital taxes remain even asymptotically we conclude by providing a brief comparison of centralized

on the theory of inflation and optimal investment policy equilibrium considerations the increase in the rate of inflation in recent years has brought forth a variety of articles concerning the effects of inflation on investment and valuation under conditions of equilibrium numerous authors 2 3 5 9 10 11 12 16 20 have derived an asset pricing model with uncertain inflation nelson 18 and kim 15 have analyzed the effects of inflation on the optimal level of investment in the capital budgeting process nelson under the assumption of perfect net operating income sensitivity states it is clear that the optimal investment will be smaller the higher the anticipated rate of inflation this result also is demonstrated to be a special case of kim s analysis while nelson and kim make important contributions their work should be extended under conditions of equilibrium chen 4 recognizing the need for an equilibrium framework has applied the asset pricing model to examination of optimal investment policy by utilizing the jensen long 15 methodology in a world of uncertain inflation the jensen long methodology is not without controversy james 13 has recently argued extending fama s 8 critique that the capital asset pricing model is inappropriate for analysis without the assumption of a perfectly competitive capital market whereas an imperfectly competitive capital market is explicit in the jensen long methodology on the other hand a competitive capital market

female labour supply flexibility of working hours and job mobility traditional labour supply models do not address to what extent working hours are constrained withinjobs and to what extent working hours can be adjusted by means of changing employer this paper measures the flexibility of working hours within and between jobs by relating subjective information on individual preferences to adjustments in working hours empirical analysis based on a sample of employed women in the dutch socio economic panel 1987 9 shows that the flexibility of working hours withinjobs is low the empirical literature on labour supply traditionally assumes that workers can choose their working hours freely and without costs up to a maximum level equal to the time endowment the potential invalidity of this assumption is acknowledged but the assumption is still often made for the tractability of the empirical model in response several models incorporating restrictions on working hours have been developed the first generation of these models extended the traditional censored regression model by allowing for censoring due to over and under employment and involuntary unemployment moffitt 1982 ham 1982 blundell et al 1987 the second generation of models extended the structural labour supply model by introducing job offers concerning hours of work van soest et al 1990 dickens and lundberg 1993 a conclusion stemming from all of these studies is that incorporating restrictions on working hours significantly improves the empirical fit of the model a peculiar component of the models discussed above is that they are static as a result they are not able to distinguish between the ingredients required for the existence of hours restrictions within the labour market first there needs to be restrictions on the possibilities to adjust working hours with the same employer for example within a job this alone does not necessarily imply that individuals are not on their labour supply curve as they might switch to an employer that offers them their preferred working hours a second necessary ingredient for the existence of hours restrictions within the labour market is therefore mobility costs although one cannot doubt the existence of hours restrictions in the labour market an open question is how tight these restrictions actually are altonji and paxson 1986 1992 study adjustments of working hours over time and distinguish between those individuals who stay in their job and those who change job change employer based on the us panel study of income dynamics they conclude that working hours of married women are two to four
