PRICING OF AMERICAN PATH-DEPENDENT CONTINGENT CLAIMS

We consider the problem of pricing path-dependent contingent claims. Classically, this problem can be cast into the Black-Scholes valuation framework through inclusion of the path-dependent variables into the state space. This leads to solving a degenerate advection-diffusion partial differential equation (PDE). We first estabilish necessary and sufficient conditions under which degenerate diffusions can be reduced to lower-dimensional nondegenerate diffusions. We apply these results to path-dependent options. Then, we describe a new numerical technique, called forward shooting grid (FSG) method, that efficiently copes with degenerate diffusion PDEs. Finally, we show that the FSG method is unconditionally stable and convergent. the FSG method is the first capable of dealing with the early exercise condition of American options. Several numerical examples are presented and discussed. ²     

Online business development services for entrepreneurs: an exploratory study

This paper addresses the use of the Internet to provide business development services such as training, consulting, counselling and networking. Using a Delphi study of experts from around the world, the possible uses of the Internet as well as criteria for successful implementation are presented. Three critical success factors for providing online services are identified. First, an effective use of online resources requires that the inherent strengths of the Internet be exploited. Using online tools when they are perceived to be a ‘second-best’ mode of communication is inefficient and can be counterproductive. Second, personal contact is still very important and can complement online services. Third, successful online services require an effective Internet site and program management. The study also shows that the specific nature of entrepreneurship and entrepreneurs must be carefully considered when developing online services. The entrepreneur is more concerned about his/her problems and is less concerned with the problems of others. However, he or she is willing to participate in a small learning network if the benefits go beyond that of just learning together. Similarly, online training for entrepreneurs should be complemented by a face-to-face component. An efficient/effective pure online training program for entrepreneurs would be very difficult if not impossible to develop and implement.     

How stock markets react to regulatory sanctions? Evidence from France

Our study of how the stock market reacts to sanction announcements by the French financial regulator from 2004 to 2017 finds that the market reacts negatively when a sanction is announced in the press. Cross-sectional regression models show that the penalties are too low to influence market reactions. Our results suggest that after the financial crisis of 2008, a plethora of news on financial wrongdoings has desensitized markets to announcements of sanctions against large companies.     

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.     

Market portfolio efficiency and value stocks

In this journal, Best, Best, and Yoder (2000) recently demonstrated that portfolios of U.S. value stocks dominate portfolios of U.S. growth stocks in terms of second-order stochastic dominance (SSD). We cannot conclude from this finding that the market is SSD inefficient, however, because market portfolio efficiency generally does not require growth portfolios to be efficient. Furthermore, stochastic dominance results are very sensitive to sampling error. In fact, the value-weighted market portfolio is not significantly inefficient, and no significant value effects exist in the sample of Best, Best, and Yoder. This study forms part of a research program on stochastic dominance. Details on the program are available at http://www.few.eur.nl/few/people/gtpost/stochastic_dominance.htm.

Shadow Price Approach to Total Factor Productivity Measurement: With an Application to Finnish Grass-Silage Production

This paper explores an intermediate route between the Fisher and the Malmquist productivity indexes so as to minimize data requirements and assumptions about economic behavior of production units and their production technology. Assuming quantity data of inputs and outputs and the behavioral hypothesis of allocative efficiency, we calculate the exact value of the Fisher ideal productivity index using implicit shadow prices revealed by the choice of input–output mix. The approach is operationalized by means of a nonparametric data envelopment analysis (DEA) model. Empirical application to Finnish grass silage farms suggests that the Malmquist and the Fisher productivity indices yield similar results when averaged over firms, but there can be major differences in the results of the two approaches at the level of individual firms.     

The trade-creating effects of business and social networks: evidence from France

Using theory-grounded estimations of trade flow equations, this paper investigates the role that business and social networks play in shaping trade between French regions. The bilateral intensity of networks is quantified using the financial structure and location of French firms and bilateral stocks of migrants. Compared to a situation without networks, migrants are shown to double bilateral trade flows, while networks of firms multiply trade flows by as much as four in some specifications. Finally, taking network effects into account divides the estimation of the impact of transport costs and of the effect of administrative borders by around three.     

Monitoring Policy and Organizational Forms in Franchised Chains

Franchising is nowadays a prominent way to organize the distribution sector. While previous literature suggests that monitoring issues are a critical determinant of organizational choices, it is rather silent on the optimal monitoring strategy once the organization of the chain is set. In this article, we analyze the monitoring policy of chains with both franchised and company-owned units. We develop a model in which a chain monitors its outlets under asymmetric information on local demands and managers’ efforts. We show that partial monitoring (i.e., when the franchisor monitors only a subset of its outlets) represents an optimal monitoring policy. Second, we identify the units that should be monitored. Finally, we discuss the impact of information technologies and outlet location on monitoring policy and how it may affect the proportion of franchised and company-owned units within the mixed chains.     

Incentives for cost misrepresentation in supply chains

This paper investigates sequential manufacturer–retailer price determination and channel performance under possible misrepresentation by one member of its privately known cost. To the standard double marginalization game, we add a preliminary stage where the manufacturer (alternately the retailer) announces its privately known constant marginal cost. We prove that the manufacturer has no incentive to misrepresent its cost, and we give respective sufficient conditions on the demand function for the retailer to overreport and to underreport costs. Depending on the shape of the demand function, opportunistic behavior by the retailer may lower or raise the manufacturer’s profit and channel performance.
