Endogenous ranking and equilibrium Lorenz curve across (ex-ante) identical countries: A generalization

This paper proposes a symmetry-breaking model of trade with a finite number of identical countries and a continuum of tradeable consumption goods, which differ in their dependence on nontradeable intermediate inputs, “producer services”. Productivity of each country is endogenous due to country-specific external economies of scale in its service sector. It is shown that, in any stable equilibrium, the countries sort themselves into specializing in different sets of tradeable goods and that a strict ranking of countries in per capita income, TFP, the service sector share, and the capital–labor ratio emerge endogenously. Furthermore, the distribution of country shares, the Lorenz curve, is unique and analytically solvable in the limit, as the number of countries grows unbounded. Using this limit as an approximation allows us to study what determines the shape of distribution, perform various comparative statics and to evaluate the welfare effects of trade. In doing so, this paper extends the analysis of Matsuyama (Econometrica, 81:5 (September 2013), 2009–2031) for more general and flexible forms of scale economies. It turns out that the technique introduced in Matsuyama (Econometrica, 81:5 (September 2013), 2009–2031) is useful for the equilibrium characterization in this general case as well. Although some results of comparative statics and on welfare inevitably need to be modified, they change in ways that illuminate the underlying mechanism of symmetry-breaking.     

Pointing Out Differences: Consumer Evaluations of Comparative Information Across Product Types

The purpose of this study is to investigate the impacts of comparative claims across search and experience product types. Data was obtained from 159 Taiwanese college students. Results reveal that comparative claims used in blogs (compared to those in print ads) produce lower counterarguments and consumers more easily accept claims made on a blog. Comparative claims lead to higher brand attitude and purchase intention for search products on the blog; however, noncomparative ads lead to higher brand attitude and purchase intention for experience products on the blog. For both search and experience products, there is no significant difference.     

Grading Innovation in an International Marketing Course: Promoting Student Collaboration and Individual Accountability

In this article, the author proposes an innovative, exam-based homework grading method to facilitate both collaboration among students and individual accountability while learning a complex theory and applying it to solve a problem. Results from this novel approach to grading a comparative advantage theory homework assignment, using an objective exam performance measure to adjust original homework grades, show that students increase their comprehension of the frequently misunderstood theory. This novel grading method can be applied in a variety of contexts to promote student collaboration in preparation of academic work while providing incentives to encourage individual accountability and engagement.     

What Drives the Historical Formation and Persistent Development of Territorial States?

The importance of the length of state history for understanding variations in income levels and growth rates across countries has received a lot of attention in the recent literature on long‐run comparative development. The literature, however, is silent about its origins. This paper explores the determinants of statehood by considering the potential roles of an early transition to fully‐fledged agricultural production, the adoption of state‐of‐the‐art military innovations, and the opportunity for economic interaction with the regional economic leader. The results demonstrate that only the association between economic interaction and the rise and development of the state is statistically robust.

Institutions as constraints and resources: Explaining cross‐national divergence in performance management

This article compares performance management practices in call centres from four telecommunications firms in the United Kingdom, France, Denmark, and Germany. Findings show that different combinations of institutional constraints, such as strong job security protections, and participation resources supporting worker voice were influential in shaping choices among policies to motivate and discipline workers. Performance management most closely approached a high‐involvement model where both constraints and resources were high, where worker representatives were able both to restrict management's use of sanctions and to establish procedures that improved the perceived fairness of incentives. Findings contribute to debates concerning the role of contextual factors in the design and effectiveness of HRM.     

Ronald Jones's duality analysis as a foundation for applied general‐equilibrium modeling

Ronald Jones made seminal contributions to general‐equilibrium theory, moving away from an emphasis on the existence of equilibrium to algebraic formulations which enabled us to characterize key relationships between parameters and variables, such as that between tariffs and domestic factor prices and welfare. But the analysis remained limited in value for policy evaluation: the analysis was local, it provided only qualitative results, it was limited to very small models, and strictly interior solutions had to be assumed. The contribution of this paper is largely pedagogic and methodological. I show how the tools and approach pioneered by Jones can be generalized via the use of duality, complementarity and the Karush–Kuhn–Tucker theorem into a global, quantitative analysis of large changes in high‐dimensional models which also allows for regime changes and corner solutions. I then show how the resulting nonlinear complementarity problem directly translates into a numerical model using the General Algebraic Modeling System (GAMS).     

A UNIFIED PRESENTATION OF COMPETITION ANALYSIS IN TWO-SIDED MARKETS

The goal of this paper is to present quantitative tools to manage competition policy analysis in two-sided platforms, based on a common framework for transaction and non-transaction platforms. We explore tools for relevant market definition [Critical Loss Analysis and a small but significant non-transitory increase in price (SSNIP) test], unilateral effects indicators [Upward Pricing Pressure (UPP) and Gross Upward Pricing Pressure Index (GUPPI)] and tests for exclusionary practices. We review dispersed results in the literature and fill the gaps where appropriate. We highlight the required changes from the usual one-sided market framework and tools. While discussions of antitrust tools can be found in specialized forums devoted to advances in competition policy analysis, we organize the material in an integrated framework.
