The Nonparametric Approach to Applied Welfare Analysis

Changes in total surplus are traditional measures of economic welfare. We propose necessary and sufficient conditions for rationalizing individual and aggregate consumer demand data with individual quasilinear and homothetic utility functions. Under these conditions, consumer surplus is a valid measure of consumer welfare. For nonmarketed goods, we propose necessary and sufficient conditions on input market data for efficient production, i.e. production at minimum cost. Under these conditions we derive a cost function for the nonmarketed good, where producer surplus is the area above the marginal cost curve.

Equalizing tax bases or tax revenues under tax competition? The role of formula apportionment

This paper contributes to the literature on fiscal equalization and corporate tax competition. The innovation is that we explicitly model multinational enterprises and a corporate tax system that is designed according to formula apportionment. Two main results are obtained. First, in contrast to previous studies we identify cases where tax revenue equalization is better in mitigating detrimental tax competition than tax base equalization. Second, tax base equalization nevertheless has the advantage that it may render tax rates efficient, depending on the shape of the apportionment formula. A pure payroll formula does not ensure efficiency, but a back‐of‐the‐envelope calibration of our model to Canadian provinces suggests that a pure sales formula may be optimal.     

A MODEL OF MONOPOLISTIC COMPETITION WITH PERSONAL INCOME DISPERSION

We introduce non‐homothetic preferences in the Dixit–Stiglitz model of monopolistic competition, and enquire about the effects of a change in income dispersion on the firms’ optimal decisions and market equilibrium. Income dispersion, modeled as a mean preserving spread, is shown to affect only the degree of product differentiation under the standard negligibility hypothesis on the firms’ decision making process, while it generates a positive co‐movement of demand and demand elasticity, when this assumption is removed and the price index effect is taken into account.     

Proof of nonparticipation in a price fixing conspiracy

When a group of firms colludes on price, the industry price will rise even when there are some firms that do not participate in the conspiracy. If the government or private parties file antitrust suits, the noncolluders face the problem of establishing their innocence since their prices rise along with those of the colluders. We propose a simple output test. Under various models of oligopoly pricing—Bertrand, Cournot, and Stackelberg—we show that the colluders restrict their output while the noncolluders take advantage of the higher price by expanding their outputs. Thus, distinguishing between colluders and noncolluders involves simply observing the output behavior of the industry members.The authors appreciate the support of the Public Policy Research Center at the University of Florida. We regret that B&R Associates is purely imaginary as is the industry.     

Exploring costs and benefits of compliance with HACCP regulation in the European meat and dairy sectors

A Hazard Analysis and Critical Control Point (HACCP) Program was introduced as a mandatory measure in the EU in the 1990s. Despite its impact on the food industry, only limited literature addresses the issue of cost and benefits of HACCP at the firm level in Europe. This paper illustrates the results of a pilot study on case studies in Italy, UK and The Netherlands, providing a first assessment of the order of magnitude of costs of compliance and a qualitative illustration of the main benefits perceived by producers.     

VERTICAL DIFFERENTIATION AND THE DISTRIBUTION OF INCOME

The paper analyses the effects of income concentration on the behaviour of a duopoly with vertical product differentiation and uncovered market. By using a trapezoid distribution, we solve explicitly for market equilibrium as a function of a mean preserving spread of the income distribution. We show that overall more concentrated incomes imply stronger product differentiation, as the presence of a large share of middle‐income consumers stimulates a price competition, whose effects are dampened through an enlargement of the quality spread. While the high‐quality advantage and market coverage increase unambiguously in the degree of income concentration, the behaviour of prices is non‐monotone in the distribution parameter.     

The implementation and structuring of divestitures: the unit's perspective

Existing literature on value creation of divestitures focuses on their antecedents, typically relating them to the parent company's financial performance. Whether and how divestitures can create value for the divested unit remains unclear. This paper presents an exploratory study based on multiple cases, to examine which factors of the implementation and structuring of a divestiture may increase the performance of a divested unit. The emergent granular framework consists of previously unreported aspects of the divesting process and provides new insights into divestitures and their outcomes. Results indicate that antecedents alone may be insufficient for understanding the outcomes of divestitures. Different combinations of understanding of the rationale for the divestiture and perceived capabilities in the divesting process affect perceptions of divestiture feasibility. Sense of opportunity emerges as the key element of the divesting process for the success of divested units. Factors that participate with sense of opportunity in determining the success of divested units are further considered in the theoretical framework. Copyright © 2010 John Wiley & Sons, Ltd.     

Collective Choice and Voluntary Provision of Public Goods*

Some public goods are provided entirely with private contributions, others with a mixture of public and private funding, and still others are entirely publicly funded. In order to study this variation, a model of dual provision is developed that endogenizes public and private funding. Households vote over an income tax that finances public supply of the good and on whether to permit private contributions. While permitting private contributions may lead to a reduction in total provision, a majority always favors permitting private contributions. Results are developed for small and large economies, and the relevance of nonexcludability and noncongestion are investigated.     

Drug‐related violence and the decline in the number of Mexican cross‐border workers

This study examines how variations in homicide rates in Mexico are associated with the likelihood of participating in cross‐border work, that is, living in Mexico but working in the U.S. Based on Mexican census data from 2000, 2010, and 2015, and information on homicides, a series of ordinary least squares models are estimated to analyze the relationship between cross‐border commuting and homicide rates at the individual level. Fixed effects models are also estimated to study this relationship at the municipal level. The results show that from 2000 to 2010 the increase in homicide rates in northern border municipalities in Mexico reduced the likelihood of being a cross‐border worker, while from 2010 to 2015 the decrease in the homicide rate increased the probability that workers engage in cross‐border work. The decline in the number of cross‐border workers is likely in part a result of the escalation in drug‐related violence that may have led them to change their country of residence.
