Estimating labor supply and production decisions of self-employed farm producers

This paper proposes a model oriented towards integrating farm households' production and consumption decisions into a unified theoretical and econometric framework. It is argued that, in contrast with other forms of economic organization, farm households' utility and profit maximization decisions are not likely to be independent.Econometric estimation of a farm-household model using Canadian data suggests that utility and profit maximizing decisions are not indeed independent and, moreover, that there are significant gains in explanatory power and efficiency by estimating the consumption and production equations jointly.     

ANARCHY AND AUTARKY: ENDOGENOUS PREDATION AS A BARRIER TO TRADE*

This article presents a general equilibrium two‐country Ricardian trade model with endogenous transactions costs that arise from individual utility‐maximizing allocation of labor to production and piracy. In the absence of institutions for risk sharing and coordination of defense, autarky obtains over most of the parameter space. When both trade and predation are supported in equilibrium, terms of trade effects can make security immiserizing. In that case, paradoxically, predation creates trade.     

Family labour supply: some empirical results from agriculture

The family is often taken as the decision-making unit in utility maximizing theories of labour supply. At a simple level, the family is composed of two elements, dependents and workers. This paper seeks to quantify the influence of these two elements on family labour supply in agriculture. Family farms are particularly suited to such analysis since institutional rigidities, like the fixed working week, are absent. Econometric methods are used on data from farms in the north-west of england for the year 1976/7. The cross-sectional study uses single equation methods. The results show that only family composition determines the labour supply of the farm family: they can then be used to quantify the effects of individual groups of dependents and workers on family labour supply.     

Theory of the firm in relation to exchange rates,import substitution and export

Neoclassical theory deals with the profit maximizing beheviour of the firm in a closed economy. Once an open-economy condition is introduced, the impact of the exchange rate on the cost and price parameters of the firm and, consequently, its import substitution and export decisions becomes relevant. A model is presented with case studies in which, given the exchange rate, the firm seeks to determine the optimal level of import substitution, output and export with the objective of maximizing its profit. In today's competitive world when countries are liberalizing and moving towards an open trade regime, the influence of exchange rates on the decision-making processes of firms is bound to be significant. An approach which provides them with a methodology for spelling out their options and making optimal choices is, therefore, of considerable practical interest.     

Aggregation of Utility and Equivalence Scales: A Solution to the Pangloss Critique

Definitions of equivalence scales are usually based on a household utility function. This may be founded on an assumption of the household maximizing a welfare function of individual utilities. Basing inter-household comparisons of welfare on this approach is fallacious because households put different weight on the utility of the various household members, a weighting that does not necessarily correspond to an ethically sound aggregation of utility. This is called the Pangloss critique. To solve the problem, I suggest keeping the model of household behavior, but to introduce a new function to aggregate the household members' utilities. Equivalence scales based on this approach are shown to have desirable properties.     

A model of benefit and tax share discrimination by a monopoly bureau

This paper integrates the theory of demand for publicly provided goods in a democracy with the theory of bureaucratic supply in order to develop a model of benefit share and tax share discrimination by a monopoly bureau. The demand side of the political market is based on a utility maximizing model of voter behavior with voters' demands aggregated through a majority voting process. The supply side of the political market is based on a budget maximizing model of bureaucratic behavior. The bureau is assumed to possess monopoly power as a result of either its control over benefit shares or tax shares and, hence, implicit tax prices or its control over budget proposals placed on the agenda. Different degrees of discrimination are examined and in each case the equilibrium of the model yields a total budget for the bureau as well as distributions of benefit shares or tax shares across voters.     

农民工加入工会的会费问题

采用VNM效用函数对农民工加入工会的会费问题进行了研究,得出农民工意愿的会费水平与侵权概率及被侵权的工资份额正相关的结论,并指出这一会费水平使工会实现了利润最大化却对农民工没有任何助益。工会是一种非盈利的公共组织,其会费水平的确定应遵循公平会费原则。公平会费使工会的期望利润为零,而农民工的福利却得到了最大化的增进。由于不同行业具有不同的公平会费,所以在实行统一的会费水平的情况下,应逐步建立起不同行业工会之间的转移支付制度,同时政府也应对侵权问题严重的行业给予更多关注和资金支持,以利于这些行业顺利组建工会及开展维权工作。     

Optimal export taxes in a multicountry framework

This paper extends the optimum export tax analysis to multicountry partial (PE) and general equilibrium (GE) frameworks, using a computable general equilibrium (CGE) model of the global cocoa market. Analyzing myopic optimum, Nash optimum and Nash revenue maximizing taxes, we show that optimum and revenue maximizing taxes obtained in the GE framework differ from their PE counterparts, as they are determined not only by the elasticity of the residual demand curve facing the country, but by domestic supply conditions as well. Second, not only are Nash revenue maximizing taxes higher than Nash optimum taxes in the GE, but, paradoxically, the society attains a higher level of welfare under Nash revenue maximizing taxes than under Nash optimum taxes. Finally, we show that the frequent use of Lerner symmetry [Lerner, A.P., 1936. The symmetry between import and export taxes. Economica 11, 306–313.] in the policy-oriented analysis of optimum export taxes is not warranted.     

National Treatment and the optimal regulation of environmental externalities

Abstract. We analyze the role of National Treatment in the regulation of environmental product standards for an open economy. A social planner uses product standards to control emissions from the consumption of a traded good. We show that whether National Treatment of standards interferes with welfare‐maximizing policy depends on the instruments available to the policy maker (consumption or emissions tax) and differences in the cost of complying with the standard. We also highlight the asymmetric incidence of the domestic and import product standard when taxes are suboptimal. This asymmetric incidence can also cause welfare‐maximizing policy to violate National Treatment.     

How does reciprocal behaviour of workers influence the wage setting of unions?

Traditional wage setting models assume that unions maximise the total income of workers, whereas actually they should maximise worker utility. These models implicitly equate utility with income, but this is not valid if workers’ utility depends on their sense of fairness and includes a non-pecuniary benefit from work. This paper presents a model combining efficiency wages with bargaining theory, drawing inspiration from the gift-exchange approach by Akerlof [Q J Econ 97(4):543–569, 1982]. It shows that the mutual gift exchange between firms and workers generates a non-pecuniary benefit which contributes to the workers’ utility in a non-monotonic way depending on the strength of workers’ sense of fairness. The model shows that if an employment subsidy is paid to workers it generates more jobs than when paid to firms. This paper is based on research which was performed while the author was employed at the University of Maastricht (The Netherlands).

WEARING OUT YOUR WELCOME: EXAMINING DIFFERENTIAL MEDICAID ELIGIBILITY OF NEW ENTRANTS AND CONTINUING RECIPIENTS

Until recently, states were permitted to have different “new entrant” and “continuing recipient” income limits for parental Medicaid eligibility by implementing income disregards that changed with spell length. Some states utilized this option—either tightening income limits for the same family over time or loosening them. In this article, we construct a theoretical model of utility‐maximizing workers facing different time‐dependent eligibility thresholds to predict the Medicaid participation and employment behavior of workers with varying wage levels. The model reveals some inter‐temporally perverse incentives created by linking eligibility thresholds to Medicaid duration. Then, we empirically test these predictions using the Survey of Income and Program Participation and a unique compilation of state‐by‐family size Medicaid thresholds for both new and continuing recipients. We find that patterns of Medicaid participation and spell duration are consistent with the predictions of our model. There is also evidence that the individuals predicted by our model to lower their work hours may supply fewer hours of labor. As of January 2014, the Affordable Care Act disallows time‐varying income disregards; our findings suggest that states previously using this strategy will experience an adjustment in Medicaid caseloads and possibly labor market outcomes because of the change.

Globalization,product differentiation,and wage inequality

Abstract This paper develops a two‐country, general equilibrium model of oligopoly in which the degree of horizontal product differentiation is endogenously determined by firms’ strategic investments in product innovation. Consumers seek variety and product innovation is more skill intensive than production. Stronger import competition increases innovation incentives, and thereby the relative demand for skill. An intra‐industry trade expansion following trade liberalization can therefore increase wage inequality between skilled and unskilled workers. As long as some industries remain shielded from international competition, the welfare implications of globalization are found to be generally ambiguous.     

Economic Growth and International Trade: The Case of Hong Kong

This paper estimates the major factors of growth of Hong Kong using a fairly new approach, which allows the direct inclusion of the factors of growth in the growth equation to be estimated. The growth factors that are found to be important for Hong Kong are physical capital accumulation, (negative) growth of unskilled workers, education, technology spillover (from foreign countries) through retained import of capital goods and inward direct investment, and learning‐by‐doing through import and domestic manufacturing production. The results strongly suggest that other than primary factor accumulation, education, trade, and foreign direct investment have contributed a lot to the growth of the economy.     

A systemic approach to modelling and estimating demand for money(ies)

This article uses a consumer theory-based systemic approach to model the demand for monetary liquid asset holdings in Chile. We implement the suggestions and caveats of aggregation theory for the estimation of a demand system for liquid assets (monies) in static, dynamic and time-varying parameters setups. Our results are robust and theoretically consistent with consumer theory restrictions, as a system derived from a utility maximizing framework and a quasi concave utility function. In our estimations, we find stability of interest rate elasticities, in contrast to previous related literature. We also document evidence that long (short) maturity rates are associated to less (more) liquid assets.     

On income fluctuations and capital gains

We consider the infinite time horizon problem of asymptotically maximizing the expected accumulated discounted utility in a one-good production economy. The available capital in a given period is given by the production of the previous period plus a random variable. The product of the discount and interest factors is either (1) greater than or (2) equal to one. Under (1) the optimal policy exists under certain conditions and always under (2). The optimal capital sequence almost surely goes to infinity. Under (1) with conditions on the utility one almost surely reaches a capital level above which the sequence is increasing.     

International trade,job training,and labor reallocation

A large literature studies the impact of increased import competition on workers' outcomes, however, relatively few studies examine which policies can aid workers displaced by trade. In this article, we evaluate the impact of an industrial job training program in Brazil on workers displaced from manufacturing sectors. We find that industrial training increases the probability of re-entry into the formal labor market 1 year after displacement by about 17 percentage points and is even more effective for workers displaced from sectors exposed to high import competition. This effect is mainly associated with workers switching sectors and occupations after training.     

Tanzanian formal sector workers' participation in informal production

A theoretical model is developed explaining formal sector workers participation in the informal sector. A reduced-form informal sector participation function is derived from a specific utility function, a specific informal sector production function, and a specific informal sector earnings function. The participation function can be estimated consistently, and provides a solution to the problem that informal sector ‘wages’ in developing countries are hard to observe. A sample of Tanzanian formal sector workers is used to estimate the participation function. A majority of Tanzanian formal sector workers participate in informal production. Participation in informal production is inversely related to household income, to living in Dar es Salaam, and to being a mother with small children. Participation is positively related to age, and multiple-job-holding seems to play a very different role in the transition from work to retirement in Tanzania compared to industrialized countries.     

Two Tales on the Returns to Education: The Impact of Trade on Wages

This paper uses micro data from the Current Population Survey combined with data from the US International Trade Commission and Bureau of Economic Analysis to evaluate the impacts of international trade (import penetration and export intensiveness) on wages with a special focus on the returns to education. Consistent with the literature, our empirical analysis provides evidence that the wage rates of similarly skilled workers differ across net‐exporting, net‐importing, and nontradable industries. Our results add to the literature by showing that the wage gap usually found across importing and exporting industries vanishes for highly skilled workers (workers with college degree and beyond) when we control for the cross‐effect between international trade and education, but the wage gap due to international trade still persists for low‐skilled workers. This finding supports the view that education serves as an equalizer and counterbalances the adverse impact from import penetration on wages of highly skilled workers.     

ECONOMIC INCENTIVES FOR AN URBAN BIAS IN DEVELOPMENT POLICIES*

This paper presents a labor turnover model in which urban employers have an economic incentive to support an urban bias in development policies because of the indirect effect of rural incomes on urban training expenditures through the rate of labor turnover. A comparative static analysis of the model shows that an income transfer from rural workers to urban workers increases the profits of urban employers, even if urban employers are not directly involved in the transfer. Unlike previous versions of the labor turnover model, worker behavior is explicitly grounded in utility maximization.     

The effects on agriculture in the United States of an oil import fee

This paper focuses on the effect that a crude oil import fee would have on the various producing sectors, consuming sectors and household categories in the United States where the interrelationships between these entities is explicitly considered. Special attention is given to the agricultural sectors of the economy. Thus, in the context of a general equilibrium model, the effect of a $5.00 per barrel import fee on the producing sectors in general and the three agricultural sectors plus forestry in particular, on the consuming sectors, on households and on the government is calculated. Over the period 1984–90 with such an import fee (relative to the absence of a crude–oil import fee), the model results suggest that there will be a reduction in output by all producing sectors (except the crude-oil industry) by about $13,924 billion, there will be a fall in the consumption of goods and services by about $318 million and there will be a decline in aggregate social welfare (measured as utility) by about $208 mill ion. The government will realize an increase in revenue of about $3,622 billion. The agricultural sectors in the aggregate can expect to see a fall in output of $769 million with an attendant increase in the price of its goods as a consequence of the oil import fee.
