A NAASTy alternative to RAND pricing commitments

Voluntary standard setting organizations (SSOs) typically require participants to disclose their patents during the standard-setting process, and will endorse a standard only if patent holders commit to license them on reasonable and non-discriminatory or RAND terms. This policy is unworkable—the RAND standard is ambiguous and thus extremely hard to adjudicate. As an alternative, a policy of Non-Assertion After Specified Time, or NAAST pricing, is proposed. Under NAAST, technology vendors commit not to assert their patent after some previous specified time, but would be free to collect royalties as they wish up until that point. Under this proposal, technology producers would be compensated, vendors would have quick and eventually free access to standards and a large element of uncertainty due to litigation would be eliminated.     

Opportunism in Buyer–Supplier Relations: New Insights from Quantitative Synthesis

After more than two decades of empirical research examining opportunism, a wide divergence of empirical findings regarding opportunism's antecedents remains. The need for more theoretically practicable and managerially actionable insight into the identity, nature, and scope of the antecedents to opportunism is clear. As such, a meta-analysis of the opportunism literature was conducted to (a) investigate the role of six antecedents (dependence, formalization, centralization, control, uncertainty, and relational norms), (b) resolve the disparate relationships' magnitudes and directions, and (c) identify moderators that might explain the disparate effect sizes. Findings suggest extant research findings are affected by socially desirable response bias; the particular operationalization of constructs, for example, whether measured opportunism is actual or perceived or whether the study omitted key antecedents; and whether the sample included firms offering products or services. Theoretical and managerial implications are developed and discussed.     

EXPORT DIVERSIFICATION IN LATIN AMERICA AND THE CARIBBEAN

Beginning in the mid-1980s the primary development paradigm pursued by Latin American and Caribbean countries undertook a major shift from the concept of import-substitution-industrialization (ISI) to that of export-led growth and openness to international markets. Despite these efforts, virtually no research has been undertaken to assess the degree to which the export structures of Latin American and Caribbean countries have in fact diversified. This is unfortunate as the trade policy environment facing these countries is poised to undergo significant changes. The purpose of this article is to examine the structure of exports to the United States from 19 selected Latin American and Caribbean countries over the 1989 to 2000 period to assess the degree to which export diversification has occurred. The analysis is conducted at a reasonably disaggregate level using 2-digit HTS data. The countries included in the analysis provide a very interesting mix of commonalities and differences. The results suggest wide differences in the degree of diversification exhibited and suggest that these differences are related to economic size and social capability.     

Intra-household labor supply,migration, and subsistence constraints in a risky environment: Evidence from rural El salvador

We investigate the use of intra-household labor allocation as a means of risk coping when subsistence constraints matter in rural El Salvador. We show that households increase the labor supply of its male members to the family farm and abroad in the US after being subjected to adverse agricultural productivity shocks. The latter is the result of a standard substitution effect, whereas the former is the result of subsistence concerns. Theoretically, these results are not at odds with each other if these events differentially impacted rich and poor households. We also show that the earthquakes of 2001 resulted in large reductions in the number of female members who were sent abroad and large increases in hours of domestic labor supplied by female members. We argue that this result is a consequence of subsistence motives because female labor supply at home increased despite lower remuneration.     

How Large is Congressional Dependence in Agriculture? Bayesian Inference about ‘Scale’ and ‘Scope’ in Measuring a Spatial Externality

The political economy literature on agriculture emphasises influence over political outcomes via lobbying conduits in general, political action committee contributions in particular, and the pervasive view that political preferences with respect to agricultural issues are inherently geographic. In this context, ‘interdependence’ in Congressional vote behaviour manifests itself in two dimensions. One dimension is the intensity by which neighbouring vote propensities influence one another, and the second is the geographic extent of voter influence. We estimate these facets of dependence using data on a Congressional vote on the 2001 Farm Bill using routine Markov chain Monte‐Carlo procedures and Bayesian model averaging, in particular. In so doing, we develop a novel procedure to examine both the reliability and the consequences of different model representations for measuring both the ‘scale’ and the ‘scope’ of spatial (geographic) co‐relations in voting behaviour.     

Heteroskedasticity, autocorrelation, and spatial correlation robust inference in linear panel models with fixed-effects

This paper develops an asymptotic theory for test statistics in linear panel models that are robust to heteroskedasticity, autocorrelation and/or spatial correlation. Two classes of standard errors are analyzed. Both are based on nonparametric heteroskedasticity autocorrelation (HAC) covariance matrix estimators. The first class is based on averages of HAC estimators across individuals in the cross-section, i.e. “averages of HACs”. This class includes the well known cluster standard errors analyzed by Arellano (1987) as a special case. The second class is based on the HAC of cross-section averages and was proposed by Driscoll and Kraay (1998). The ”HAC of averages” standard errors are robust to heteroskedasticity, serial correlation and spatial correlation but weak dependence in the time dimension is required. The “averages of HACs” standard errors are robust to heteroskedasticity and serial correlation including the nonstationary case but they are not valid in the presence of spatial correlation. The main contribution of the paper is to develop a fixed-b asymptotic theory for statistics based on both classes of standard errors in models with individual and possibly time fixed-effects dummy variables. The asymptotics is carried out for large time sample sizes for both fixed and large cross-section sample sizes. Extensive simulations show that the fixed-b approximation is usually much better than the traditional normal or chi-square approximation especially for the Driscoll-Kraay standard errors. The use of fixed-b critical values will lead to more reliable inference in practice especially for tests of joint hypotheses.     

Structuring a tax efficient international operation

International taxation is rapidly increasing in importance in the U.S. business environment. As a student preparing for a career in public accounting or industry, it is vital that you have familiarity with key international tax issues. In this case, you will participate in a detailed tax-planning exercise involving a multinational corporation that is restructuring its tax operations. In the process, you will be exposed to a wide-ranging array of real-world tax issues: tax theory, source of income, transfer pricing, foreign tax credits, the foreign earned income exclusion and Subpart F income. The case also incorporates questions designed to help you explore the financial accounting implications of tax planning. The case consists of three tax modules and each module emphasizes two to three specific tax issues. Two of the modules also contain a subset of tax-related financial accounting questions. To complete the case successfully, you will be required to understand basic international tax theory, to engage in the tax research process and to apply your theoretical knowledge in analyzing complex business scenarios.
