Exports and labor costs: evidence from a French policy

We investigate the role that labor costs hold in exporters’ performance. To do so, we exploit a large-scale French reform that granted most firms a tax credit proportional to the wagebill of their employees paid below a given threshold. This policy effectively translated into a cut in labor cost whose magnitude varies depending on firm-specific wage structures. We use the predicted treatment intensity based on pre-reform composition of the labor force as an instrument for the actual policy-induced firm-level change in labor costs. Although our point estimates are consistent with commonly estimated firm-level trade elasticities combined with reasonable labor shares in total costs, coefficients are found to be very noisy, suggesting lack of robust evidence of a causal effect of the policy. We discuss several potential explanations for our results as well as their implications.     

Pricing and hedging S&P 500 index options with Hermite polynomial approximation: empirical tests of Madan and Milne's model

The universal use of the Black and Scholes option pricing model to value a wide range of option contracts partly accounts for the almost systematic use of Gaussian distributions in finance. Empirical studies, however, suggest that there is an information content beyond the second moment of the distribution that must be taken into consideration.This article applies a Hermite polynomial-based model developed by Madan and Milne (1994) to an investigation of S&P 500 index option prices from the CBOE when the distribution of the underlying index is unknown. The model enables us to incorporate the non-normal skewness and kurtosis effects empirically observed in option-implied distributions of index returns. Out-of-sample tests confirm that the model outperforms Black and Scholes in terms of pricing and hedging. © 1999 John Wiley & Sons, Inc. Jrl Fut Mark 19: 735–758, 1999     

Intertemporal substitution in import demand and habit formation

To study non-durable import demand, we extend previous work done by Clarida (1994) and Ceglowski (1991) by considering a two-good version of the lifecycle model in which we introduce time-non-separability in the households' preferences. The model is estimated using quarterly data for the USA and France. Using the information contained in the observed stochastic and deterministic trends, we derive a cointegration restriction used to estimate curvature parameters of the instantaneous utility function. The remaining parameters are estimated in a second step by GMM. The constancy of the different parameters is investigated, in both the long and the short run. Habit formation turns out to be an important factor of import demand. © 1998 John Wiley & Sons, Ltd.     

International tax competition: do public good spillovers matter?

We study the impact of public good spillovers on tax competition between two imperfectly integrated countries with different levels of productivity. We show that international public good spillovers, by reducing the tax gap between countries, strengthen the agglomeration of firms in the most productive country. Then we carry on a welfare analysis. We first assume that governments are engaged in a redistributive tax policy. At the non-cooperative equilibrium, the tax level in the high-productivity country is inefficiently high while it is inefficiently low in the other country. A different conclusion emerges when tax revenues are recycled in a public good provision: taxes are inefficiently low in both countries and public good spillovers increase the global welfare. Finally, for a given amount of total tax revenues, public good provision in the high-productivity country is inefficiently high compared to its level in the low-productivity country.     

The curious destiny of a heterodoxy: The Austrian economic tradition

The Austrian School has had a curious destiny: while contributing many concepts to contemporary economic theory, it is either ignored or criticised by much of modern economic literature. This article discusses possible reasons for this institutional sidelining and the main futures of a renewal of Austrian thought.

Power in the multinational corporation in industry equilibrium

Recent theories of the multinational corporation introduce the property rights model of the firm and examine whether to integrate or outsource firm activities locally or to a foreign country. This paper focuses instead on the internal organization of the multinational corporation by examining the power allocation between headquarters and subsidiaries. We provide a framework to analyse the interaction between the decision to serve the local market by exporting or FDI, market access and the optimal mode of organization of the multinational corporation. We find that subsidiary managers are given decision power to run the firm at intermediate levels of host country competition. We then provide comparative statics on the optimal organization of the multinational corporation for changes in fixed FDI entry costs, trade costs, as well as changes in information technology.      

Luxury without guilt: service innovation in the all-inclusive hotel industry

With more than 500 all-inclusive resorts around the world, competition in this sector is intense and resorts are constantly trying to gain a sustainable competitive advantage through innovation. The main aim of this article is to investigate the issue of non-technological innovation in the holiday resort industry, in general, and, in particular, how such innovation has enabled the success of ultra all-inclusive concept. The article is based on the case of the Excellence group, analysing the factors behind the success of their business model and its sustainability.
