Exceptional performance of multinational suppliers: theory and evidence

Review of World Economics - This paper focuses on an unexamined area of trade—the behaviour of heterogeneous intermediate suppliers facing final producers of different ability and pursuing...     

Multilateral Reforms of Trade and Environmental Policy

The paper analyzes environmental tax policy reform using a competitive model of world trade that includes production‐generated environmental damage (pollution) and trade tariffs. The authors examine the feasibility of Pareto‐improving multilateral reforms of environmental taxes, and show that any environmental tax reform that is mutually welfare‐improving when compensating lump‐sum transfers are assumed is also welfare‐improving when a suitable tariff reform (but no transfers) is combined with the tax changes. Several specific reform proposals are developed. These results expand the feasible set of mutually improving policy proposals for international policy initiatives.

THE EFFECT OF MINIMUM WAGES ON UK AGRICULTURE

Since the abolition of the Wages Councils in September 1993, agriculture is the only sector in the UK economy covered by any form of minimum wage legislation. However, the recent denunciation of an ILO convention covering minimum wages in agriculture has paved the way for the abolition of the Agricultural Wages Boards. This paper investigates the impact of the system of minimum wages on the level and structure of earnings and employment in agriculture. On wages, our main conclusion is that the minimum wages set by the Agricultural Wages Boards are important determinants of the average level and distribution of earnings in UK agriculture. On employment, our main conclusion is that there is no evidence that minimum wages have reduced the level of employment in agriculture. If anything, our estimates imply a weak positive, though statistically insignificant, impact of minimum wages on employment. This seems to be true when we disaggregate by sex and skill.     

The Reverse Favourite–longshot Bias and Market Efficiency in Major League Baseball: An Update

Racetrack and sports betting markets have been researched extensively with respect to the question of market efficiency. In contrast to the consistently observed favourite–longshot bias found in racetrack betting markets, it has been shown that gamblers in the market for Major League Baseball games reveal the opposite behaviour. This paper updates the previous study with ten years of additional data for the 1990–99 seasons. The strength of the reverse favourite–longshot bias is virtually identical to the original paper. The result suggests that, contrary to most reported inefficiencies in gambling markets, this bias appears to be permanent.     

Tariff strategies and small open economies

In this paper we examine the issue of optimal tariffs for a small economy that trades with a large economy. We define 'small' and 'large' in the sense that the world prices are determined solely by the large country, and, therefore, the small country faces exogenously given world prices. Within this framework it is shown that there exist situations in which the small country has an incentive to behave as a Stackelberg leader by committing itself to a non-zero optimal tariff. Although the small country is unable to directly affect world prices, by pre-committing to a non-zero trade tax it may induce a reduction of the large country's optimal trade tax, thereby indirectly improving its terms of trade and welfare.

Stratégies de droits de douane et petites économies ouvertes. Ce mémoire examine le problème des droits de douane optimaux pour une petite économie qui commerce avec une grande. On définit 'petit' et 'grand' en un sens économique: les prix mondiaux sont déterminés seulement par le grand pays et le petit pays fait face à des prix mondiaux exogènes. A l'intérieur de ce cadre d'analyse, les auteurs montrent qu'il existe des situations dans lesquelles le petit pays est incitéà se conduire en leader à la Stackelberg en s'engageant fermement dans une politique de droit de douane optimal différent de zéro. Même si le petit pays ne peut pas influencer directement les prix mondiaux, en adoptant une politique ferme de droits de douane positifs, il peut amener le grand pays à réduire son niveau de droit de douane optimal, et, ce faisant, améliorer ses propres termes d'échange et son propre niveau de bien-être.     

Risk preference,immigration policy and illegal immigration

The paper analyzes the effects of government policy upon illegal immigration. The model used as a vehicle for this analysis is an extension of Ethier's one-small-country model of illegal immigration to a two-country context. We distinguish between the cases of capital immobility and free capital mobility, and consider illegal immigration when there are border patrols by the government and when there are internal enforcement procedures in effect. Unlike previous researchers who have assumed risk neutrality, we examine the impacts of government policy when prospective illegal immigrants exhibit risk averse and risk loving behavior. The relaxation of the risk neutrality assumption leads to the possibility of multiple and unstable equilibria. Moreover, attitudes to risk and the probability of detection are shown to have implications for some equilibrium responses to tighter surveillance.     

On testing weak separability

A new framework for testing for the existence of a consistent aggregator for a subset of inputs in a production function is developed in terms of the variable profit function. In contrast to the Berndt–Christensen framework, in which the parametric restrictions required to attain weak separability also impose unwanted restrictions on the form of the aggregator, the aggregator function has a flexible functional form. Consequently this procedure should permit a less restrictive test of separability or aggregation. Application of the procedure to the data for U.S. manufacturing assuming a production function involving two labour inputs (blue- and white-collar workers) and two capital inputs (structures and equipment) leads to the conclusion that there does not exist a consistent aggregator for labor whereas there is some mild support for the existence of a consistent aggregator for capital.     

Multi‐product exporters,variable markups and exchange rate fluctuations

In this paper we investigate how firms adjust markups across products in response to fluctuations in the real exchange rate. We estimate markups at the market–product–plant level using detailed panel production and cost data from Mexican manufacturing between 1994 and 2007. Exploiting variation in the real exchange rate in the aftermath of the peso crisis in December 1994, we provide robust empirical evidence that plants increase their markups and producer prices in response to a real depreciation and that this increase is greater for products with higher productivity. Thus, we provide direct evidence for the theoretical mechanism of variable markup response behind incomplete and heterogeneous exchange rate pass‐through on producer prices. Our empirical methodology allows us to decompose the producer price response to exchange rate shocks into a markup and a marginal cost component using our markup estimates. Using these estimates, we establish that marginal cost at the product–plant level increases more in response to real exchange rate depreciation if the plant has higher share of imported inputs.
