Is protection really for sale? A survey and directions for future research

This paper critically and selectively surveys the literature on protection for sale and discusses directions for future research in this area. It suggests that the standard approach needs to be augmented to provide more compelling tests of this model.     

The knowledge management strategy and the formation of innovative networks in emerging industries

This paper presents an agent-based simulation model with local network externality to analyze strategic interactions over investment on new economic knowledge. R&D knowledge flows and spillovers are the results of non-cooperative games played between neighboring agents in the model. The model demonstrates a situation where no agents have incentives to hide their economic knowledge, a situation that is observed in open source software development projects. The likelihood of obtaining a stable situation where new economic knowledge is openly shared is increased when heterogeneity of agents is introduced.      

From engineer to taxi driver? Language proficiency and the occupational skills of immigrants

We examine the ability of immigrants to transfer the occupational human capital they acquired prior to immigration. We first augment a model of occupational choice to study the implications of language proficiency on the cross‐border transferability of occupational human capital. We then explore the empirical predictions using information about the skill requirements from O^*NET and a unique dataset that includes both the last source country occupation and the first four years of occupations in Canada. We supplement the analysis using Census estimates for the same cohort with source country occupational skill requirements predicted using detailed human capital related information such as field of study. We find that male immigrants to Canada were employed in source country occupations that typically require high levels of cognitive skills, but rely less intently on manual skills. Following immigration, they find initial employment in occupations that require the opposite. Consistent with the hypothesized asymmetric role of language in the transferability of previously acquired cognitive and manual skills, these discrepancies are larger among immigrants with limited language fluency.     

An analysis of entry-then-privatization model: welfare and policy implications

This study formulates a new model of mixed oligopolies in free entry markets. A state-owned public enterprise is established before the game, private enterprises enter the market, and then the government chooses the degree of privatization of the public enterprise (termed the entry-then-privatization model herein). We find that under general demand and cost functions, the timing of privatization does not affect consumer surplus or the output of each private firm, while it does affect the equilibrium degree of privatization, number of entering firms, and output of the public firm. The equilibrium degree of privatization is too high (low) for both domestic and world welfare if private firms are domestic (foreign).     

The dual attitudinal dynamics of public opinion: an agent-based reformulation of L. F. Richardson’s war-moods model

This study proposes a new model of public opinion dynamics, focused specifically on attitudes toward war. The model consists of citizen-agents who have dual (public and private) attitudes. While they change the two levels of attitude according to different rules of two-layered interactions with neighboring agents, they also change their own attitudes internally. Our model shows that public opinion has “meta-stable” states, which generate overlapping, or two-valued, stable states. This characteristic can explain how public opinion responds to the outbreak and continuation of war very differently, not just in our model, but also in the opinions of European citizens on the First World War and those of American citizens on U.S. wars after the Second World War.
