The optimal method for pricing Bermudan options by simulation

Least‐squares methods enable us to price Bermudan‐style options by Monte Carlo simulation. They are based on estimating the option continuation value by least‐squares. We show that the Bermudan price is maximized when this continuation value is estimated near the exercise boundary, which is equivalent to implicitly estimating the optimal exercise boundary by using the value‐matching condition. Localization is the key difference with respect to global regression methods, but is fundamental for optimal exercise decisions and requires estimation of the continuation value by iterating local least‐squares (because we estimate and localize the exercise boundary at the same time). In the numerical example, in agreement with this optimality, the new prices or lower bounds (i) improve upon the prices reported by other methods and (ii) are very close to the associated dual upper bounds. We also study the method's convergence.     

Economics of advertising: Emerging functions of Internet advertising

This paper intends to highlight the emerging force of the Internet as an advertising medium. The economic functions of Internet advertising are examined. Moreover, the paper aims to evaluate the relative impacts on optimal advertising models. Our discussion also includes analysis of associated price-cost margins with respect to optimal advertising budgets and strategic reactions. All in all, this paper should provide entrepreneurs with more crucial knowledge of advertising strategies offered by the new medium. Moreover, it will equip scientists and technologists with more insights into the economic aspects and strategic values of Internet advertising. This revised version was published online in August 2006 with corrections to the Cover Date.     

Not all family firms are equal: The moderating effect of family involvement on the political risk exposure of the foreign direct investment portfolio. Preliminary evidence from Spanish multinational enterprises

We investigate the effect of political risk (PR) exposure and family control on the internationalization strategy of multinational enterprises (MNEs) using social capital theory. Our results from a negative binomial cross‐sectional analysis in 2007 of Spanish MNEs show family ownership or the limited presence of family members on the board has no effect on internationalization. However, when the conceptualization of family firms (FFs) includes majority ownership and board presence, we find a direct negative effect on their internationalization scope but a positive moderating effect on the relationship between the exposure to PR and internationalization scope. FFs have some specific advantages suitable to be employed in their corporate political activity allowing them to develop long‐lasting relationships with relevant political actors. By disentangling the effects of family control on internationalization and PR, this article explains how FFs can be simultaneously risk‐willing and risk‐averse.     

Does the sequencing of related and unrelated export diversification matter? Evidence from Colombian exporters

How does related or unrelated geographic diversification affect future related or unrelated product diversification of exporting firms, and vice-versa? This question addresses an unresolved debate, and it is important for firms in developing countries that seek to expand their product and geographical markets. Our study contributes to a current debate by highlighting the relevance of the temporal sequence and the relatedness of international diversification. Expanding the classic transaction costs and the resource-based explanations, we argue that organizational learning as well as organizational and sales (in-)efficiencies (notably through resource and product cannibalization, negative transfer and coordination costs) affect the interrelationships between product and geographic diversification. Using a panel dataset of over 14,000 firm-year observations from exporters based in Colombia, we find that (1) related geographic diversification tends to increase future product diversification; (2) related product diversification tends to decrease future geographic diversification; and (3) unrelated product diversification tends to increase future geographic diversification.     

Strategic reference points in family firms

Family firms are classically seen as risk averse organizations, and this is evident in their generally lower R&D investments compared to non-family firms. Recent research, however, challenges this predominant view and suggests that family firms can embrace higher strategic risk when faced with threats to their family-centered goals. Still, the internal and external conditions that drive variations in the strategic risk taking behaviors of family firms are little known and understood. This article adds to this literature by developing and testing a conceptual model of strategic risk taking that incorporates behavioral theory, family business literature, and the logic of the strategic reference point theory. With recognition that the interplay between family and economic goals determines heterogeneity in strategic actions of family firms, this model suggests that family managers respond differentially to the feedback information regarding internal and external reference points, and consequently identifies key drivers of variation in the R&D investment behavior of family firms. By examining the pattern in R&D investments of 437 Spanish private manufacturing firms from 2000 to 2006, this study shows how strategic inputs, strategic outputs, and external benchmarks produce variations in strategic decisions about R&D investments in family and non-family firms. The findings offer insights into how internal and external reference points are considered in family firms’ decision making, thereby contributing a deeper understanding into the circumstances under which family goals cope or collide with the economic goals of the firm, and how this influences strategic risk decisions in family firms.     

Savings, Volume of Trade, and Growth

This paper develops a two-country dynamic general equilibrium model with endogenous growth to analyze the effects of international trade on steady-stage growth. The two countries differ both in preferences and in technologies. It is shown first that both countries cannot simultaneously experience increases in consumption growth from trade. It is then shown that trade can increase output growth for both countries if the attitude towards saving matches the change in the terms of trade in each country. A country facing a decline (rise) in its output price grows faster if its intertemporal elasticity of substitution is sufficiently low (high).     

A note on the economics of the duty free zone

This note extends some of the results of Hamada (1974) on the economic effects of a duty free zone. It is shown that, in the presence of factor mobility between the duty free zone and the rest of the economy, the final equilibrium will yield the same trade pattern which would have prevailed under free trade; moreover, all of the trade will be done by the duty free zone.
