Sectoral labour supply,choice restrictions and functional form

In this paper we discuss a general framework for analysing labour supply behaviour in the presence of complicated budget and quantity constraints, of which some are unobserved. The individual's labour supply decision is viewed as a choice from a set of discrete alternatives (jobs). These jobs are characterized by attributes such as hours of work, sector‐specific wages and other sector‐specific aspects of the jobs. The labour supply model for married women is estimated on Norwegian data. Wage elasticities and the outcome of a tax reform experiment show that overall labour supply is moderately elastic, but these modest overall responses shadow for much stronger inter‐sectoral changes. Our model is compared with a discrete choice model in which the utility is assumed to be a polynomial. We show that our estimated model has a more economically sensible interpretation and fits the data as well as the alternative approach. Copyright © 2006 John Wiley & Sons, Ltd.     

Social trust environment and firm tax avoidance: Evidence from China

We examine the impact of the social trust environment in which a firm is located on its tax avoidance in China and paying attention to the moderating effect of corporate governance and state-ownership. Drawing from theoretical and empirical work on firm tax avoidance and manager–shareholder agency conflict, we hypothesize that social trust can lower firm tax avoidance. It is because a high social trust environment can reduce agency conflict so that tax avoidance is less. Our findings are consistent with our hypothesis, and robust to a battery of robustness tests. Furthermore, we document that the association between social trust and firm tax avoidance is more pronounced for firms with weak corporate governance and state-owned. Moreover, we find that firms in more trustworthy provinces present less general and administrative expenses and higher asset turnover, corroborating our theoretical foundations with respect to agency cost in our hypothesis. Our findings suggest that social trust and its interactions with corporate governance and state ownership are important internal and external determinants on the variations in tax avoidance.     

Regression‐Kink Approach for Wage Effect on Male Work Hours

In finding the effect of after‐tax wage rate on work hours, the main difficulty is the endogeneity of after‐tax wage rate that equals ‘one minus average tax rate’ times wage rate. To overcome this endogeneity problem, we take advantage of jumps in the marginal income tax rate, which is a regression discontinuity (RD) idea. This RD, in turn, makes the average income tax rate ‘kink‐continuous’, which is a regression kink (RK) idea. We provide a simple economic model resulting in the RD and RK features, explain how to implement RK in practice, and then apply our methods to Korean male data. Our main RK‐based labour supply elasticity estimate 7.16% turned out to be insignificant with t‐value 1.52, but it is much larger than most estimates in the literature. This may be attributed to, among other things, the facts that the RK instrument is unique, that RK identifies only the local elasticity at the kink point and that RK requires large data as regression derivatives are estimated.     

Coalition-enhancing fiscal policies in an open economy: A CES framework of Gale’s transfer paradox

The motivation of our paper comes from David Gale’s seminal work in 1974. He constructed an example of the “transfer paradox” based on three Leontief functions. The transfer paradox is that when there is a set of agents in the home country and that the home country is trading with other countries, then certain public lump-sum tax transfer plans could make all agents in the home country better off. Our contributions are as follows. First, we show that such an example can be constructed with three smooth CES utility functions. Second, we establish the three crucial conditions for the existence of the transfer paradox: (1) the donor (a taxpayer) has stronger preference for the foreign good than the recipient; (2) the donor is ex-ante wealthier than the recipient; (3) the elasticity of substitution of the foreign country’s preference is strictly less than one.     

Demographics and the long-horizon returns of dividend-yield strategies

This paper investigates the relationship between demographic changes and the long-run returns of dividend-yield investment strategies. We hypothesise that in a world where components of wealth are mentally treated as being non-fungible, the preference for high dividend-paying stocks by older investors means that the excess returns of high dividend-yielding stocks, relative to other stocks, should be positively related to demographic clientele variation. In particular, we find that, consistent with the behavioural life-cycle hypothesis, long-run returns of dividend-yield investment strategies are positively driven by changes in the proportion of the older population. Our results are robust when controlled for the Fama–French factors, inflation rate, consumption growth rate, interest rates, tax clienteles, time trend and alternative definitions of both dividend-yield strategies and demographic variation.     

Is tax progression really good for employment? A model with endogenous hours of work

This paper discusses the effect of tax progression on wage setting and employment in a unionised labour market. Recent contributions to this field argue that tax progression paradoxically enhances employment if wage setting is subject to collective bargaining. In this literature, individual hours of work are usually assumed to be exogenously given. We show that the positive employment effect of tax progression can be generalized to a model with a positive labour supply elasticity of individual workers. However, the wage-moderating effect of tax progression does not unambiguously carry over to a world where the union may fix both wages and individual hours of work. In this framework, the union reacts to tax progression by cutting individual working time. The wage rate, however, may decrease or increase. If the wage rate increases, the number of employed workers may decline despite the reduction in hours of work.     

Charitable Donations and the Estate Tax: A Tale of Two Hypotheses

Regression studies have suggested that reducing estate‐tax rates would lead to a net reduction in total charitable donations distributed at death. Not only is this notion counterintuitive, our empirical analysis yields the contrary conclusion: overall donations would increase. In rationalizing this donation‐decline outcome, investigators have pointed to the tax deductibility of donations in assessing estate‐tax liability. These efforts, we show, are dubious. The view that donations will decline is also shown to be inconsistent with axioms of generally accepted economic theory. Two distinct sets of indifference curves that imply these two antithetical views are suggested, their observable predictions derived and compared to the relevant evidence, showing that the increasing‐donation hypothesis is confirmed, offering overall a clear challenge to the decline‐in‐donation position. Our empirical results suggest that most estate‐tax payers possess indifference curves consistent with those that embody the increasing‐donation hypothesis.     

Evolution of preferences and cross-country differences in time devoted to market work

I model the hypothesis that preferences evolve and permanent differences in individual attitudes towards work emerge between two countries characterized initially by identical preferences as a result of a period in which only one of the two countries is subject to regulations constraining labor supply, or as a by-product of different tax rates on labor income. Hence, the elimination of these regulations may not allow the economy thus deregulated to converge to the same hours of market work per person of the other economy, and the long-run differential in market work between economies subject to different tax rates is amplified.     

Ex-dividend day abnormal returns for special dividends

Past research shows that the difference between dividend amount and ex-dividend day price drop reflects the transaction costs and the differential in the tax rates on dividends and capital gains. Moreover, it is also documented that the higher the dividend yield, the lower is the ex-dividend day return. This paper focuses on large special dividends and tests the two competing hypothesis, tax hypothesis and short term trading hypothesis. Our focus on large special dividends is motivated by the following three considerations. First, special dividends have experienced a surge in recent years. Second, special dividends are important for dividend capture by institutions, corporations and arbitragers. Third, using a sample of large special dividends allows us to reduce the market microstructure effects and focus more directly on the two competing hypotheses. Based on a sample of large special dividends, we find that price drop on ex-dividend day is significantly less than the dividend amount. Furthermore, we show that ex-dividend day returns are positive and hence, are not fully arbitraged away. Our tests indicate that tax hypothesis explains some portion of ex-dividend day abnormal returns even for large special dividends, whereas the support for the short-term trading hypothesis is weak.     

Analyzing female labor supply — Evidence from a Dutch tax reform

Among OECD countries, the Netherlands has an average female labor force participation, but by far the highest rate of part-time work. This paper investigates the extent to which married women respond to financial incentives. We exploit exogenous variation caused by a substantial Dutch tax reform in 2001. Our main conclusion is that the positive significant effect of the tax reform on labor force participation dominates the negative insignificant effect on working hours. The latter contradicts the common empirical finding of positive wage elasticities. Our preferred explanation is that women respond more to changes in tax allowances than to changes in marginal tax rates.     

Taxes and Benefits: Two Options to Cheat on the State

In this article we study the social norms to abstain from cheating on the state via benefit fraud and tax evasion. We interpret these norms (called benefit morale and tax morale) as moral goods, and derive testable hypotheses on whether their demand is determined by prices. Employing a large survey data set from OECD‐member countries we provide robust evidence that the demand responds to price proxy variables as predicted by theory. The main general conclusion of this article is that social norms (which are widely accepted as determinants of individual economic behaviour) are themselves influenced by economic factors.     

Performance management in context: formative cross-functional performance monitoring for improvement and the mediating role of relational coordination in hospitals

Recent research suggests that to fully realise its potential, performance management should be bespoke to the social context in which it operates. Here, we analyse factors supporting the use of performance data for improvement. The study purposively examines a developmentally oriented performance management system with cross-functional goals. We suggest that these system characteristics are significant in interdependent work contexts, such as health care. We propose and test that (a) relational coordination helps employees work effectively to resolve issues identified through formative and cross-functional performance monitoring and (b) that this contributes to better outcomes for both employees and patients. Based on survey data from management and employee representatives across Irish acute hospitals, the study found that perceptions of relational coordination mediated the link between formative cross-functional performance monitoring and employee outcomes and partially mediated the link between formative cross-functional performance monitoring and patient care. Our findings signal potential for a more contextually driven and interdependent approach to the alignment of management and human resource management practices. While relational coordination is important in health care, we also note potential to identify other social drivers supporting productive responses to performance monitoring in different contexts.     

Tax loss selling and the contrarian investment strategy

Tax loss selling is examined as a possible explanation for the long term price reversal patterns associated with the contrarian investment strategy. Our empirical results are consistent with a tax effect. When we adjust for size and potential tax loss selling, the abnormally high returns previously found in January are eliminated. These results suggest that short term tax effects are associated with the longer term overreaction or contrarian hypothesis, and at this point cannot be dismissed.     

Income taxes and the destination of movers to multistate MSAs

We examine how differences in state income tax rates, as well as other state and local taxes and public service expenditures, influence the choice of state of residence for households (federal tax filers) moving into multistate metropolitan areas (MSAs) using data from the IRS on the migration of taxpayers. MSAs that are on borders provide a spatial discontinuity—discrete differences in state tax rates within a single labor market. These MSAs allow residents to live in one state and work in another state. We find that differences in state income tax rates have a significant impact on the relative rate of migration to the states within an MSA. However, contrary to what would be expected, this impact is only significant in MSAs in which the filing state is based on employment (states without reciprocity) and not for those states in which the filing state is the state of residence (states with reciprocity). In MSAs where states do not have reciprocity agreements, a difference of ten percent in tax rates leads to a 4.1 percent difference in the relative rate of incoming taxpayers. Analogously, we find that a ten percent difference in state tax rates in these MSAs results in a 3.3 percent difference in the rate of tax base inflow (AGI). Our results suggest that one reason that differences in state income taxes appear to have more impact in multistate MSAs without reciprocity is that only relatively large differences in state income tax rates have any impact on migration and these differences are much more pronounced in MSAs without reciprocity.

Jealousy and underconsumption in a one-sector model with wealth preference

The present paper examines the effects of consumption externalities on economic performance in a one-sector model with wealth preference. The presence of the wealth preference generates a wealth effect in consumption growth, which plays a crucial role for consumption externalities to have impacts on the economy. Our main findings are: (i) regardless of the assumption of inelastic labor supply, the distortionary effect of consumption externalities stays in the long run; (ii) the income tax as well as the consumption tax can modify the efficiency; and (iii) the numerical simulations supplement theoretical findings.     

General equilibrium and optimal taxes

It is shown that if subsidies are not excessive, there exists a general competitive equilibrium in the presence of a complex tax structure. Furthermore, under certain continuity assumptions, a tax structure which is optimal from the social point of view can be determined. Procedures maximize quasi-concave after tax profit functions. Consumers have convex budget sets reflect- ing their income from sales and profits minus taxes on fixed income and progressive sales taxes. Their preferences are interdependent, intransitive and incomplete. The government provides public goods and determines the optimal tax regime on the basis of its preferences on the final competitive consumption allocation.     

Mixture models of choice under risk

This paper is concerned with estimating preference functionals for choice under risk from the choice behaviour of individuals. We note that there is heterogeneity in behaviour between individuals and within individuals. By ‘heterogeneity between individuals’ we mean that people are different, in terms of both their preference functionals and their parameters for these functionals. By ‘heterogeneity within individuals’ we mean that the behaviour may be different even by the same individual for the same choice problem. We propose methods of taking into account all forms of heterogeneity, concentrating particularly on using a Mixture Model to capture the heterogeneity of preference functionals.     

Expectation formation of older married couples and the rational expectations hypothesis

This paper tests the Rational Expectations (RE) hypothesis regarding retirement expectations of older married American couples, controlling for sample selection and reporting biases. In prior research we found that individual retirement expectation formation was consistent with the Rational Expectation hypothesis, but in that work spousal considerations were not analyzed. In this research we take advantage of panel data on expectations to test the RE hypothesis among married individuals as well as joint expectations among couples. We find that regardless of whether we assume that married individuals form their own expectations taking spouse's information as exogenous, or the reports of the couple are the result of a joint expectation formation process, their expectations are consistent with the RE hypothesis. Our results support a wide variety of models in economics that assume rational behavior of married couples.
