Diffusing the Cloud: Cloud Computing and Implications for Public Policy

Cloud Computing is rapidly emerging as the new information technology platform. It is, however, much more than simply a new set of technologies and business models. Cloud Computing is transforming how consumers, companies, and governments store information, how they process that information, and how they utilize computing power. It can be an engine of innovation, a platform for entrepreneurship, and driver of corporate efficiency. While an increasingly commonly term, confusion remains over what exactly constitutes Cloud Computing, how the markets are unfolding, and what forces will drive their evolution and diffusion. This paper provides an overview and conceptual tools for business leaders, policymakers, and non-specialist scholars to identify, distill, and easily understand the core aspects of how Cloud Computing service markets are developing, and how an array of policy issues will influence how this new computing platform unfolds across the world.     

Trans-boundary Pollution and Brain Drain Migration

The economic effects of international brain drain migration in the presence of trans‐boundary pollution are analyzed. In autarky, both skilled and unskilled workers are expected to migrate from the less developed foreign country to the developed home country, if permitted. Surprisingly, under certain conditions, all workers, apart from skilled foreign ones, will gain (lose) from the migration of unskilled (skilled) foreign workers. Moreover, if skilled foreign workers are employed as unskilled domestic workers, then skilled foreign workers will gain but unskilled workers in both countries will lose. Whether or not skilled domestic workers will gain depends on the magnitude of the pollution spillover parameter. Brain drain migration persists under free trade if the demand for manufactured goods is strong.     

Conflict resolution with robustness in international negotiations: A game theoretic approach

A robust game theoretic approach for constructing effective international concords for conflict solving is discussed. Ann-person cooperative game in characteristic function form is used for international conflict solving via formation of coalitions. The nucleolus and the augmented nucleolus as solution concepts of the game are derived on its alternative forms, and robustness of the solutions when the evaluation of the coalition values is varied is examined. For solving this problem, parametric linear programming is used. This approach provides in a resemblant form an-alternative device to solving the fuzzy linear programming based on interval analysis.     

Pasinetti after Sen: Towards a Capability Approach to Structural Dynamics of Consumption

Pasinetti's theory of structural dynamics has, as well as the capability approach, normative implications about income distribution and economic growth. Compared with the latter, however, the individual character of consumption is rather neglected in Pasinetti's framework, but the macro‐economic viability is examined here more intensively as a main issue. In this paper, we will show it possible and fruitful to consistently integrate both complementary approaches and present an analytical foundation of a normative theory of the structural dynamics of consumption.     

Welfare Effects of Reducing Home Bias in Government Procurements: A Dynamic Contest Model

This paper models an international contest for government procurement as a dynamic game between a domestic firm and a foreign firm. We show that trade liberalization, in the form of a reduction in bias against the foreign firm, improves both domestic and global welfare if (i) either the foreign firm's profit is sufficiently large or (ii) the initial degree of home bias is sufficiently small. If the initial home bias is large, a small reduction in the bias may reduce welfare.     

A dynamic linear economy with characteristic-based endogenous technical coefficients

We develop a characteristic-based model for the endogenous determination of technical coefficients in a linear economy and use it to describe the dynamics of the economy as driven by changes in knowledge. The use of the characteristic approach to determine technical coefficients makes our model suitable to be interpreted as a first attempt towards the formulation of a formal knowledge-based model of technology.     

Marketing Channels and Retail Store Density in East Asia*

By measuring retail store density with regard to population, several studies have indicated that marketing channels in Asia are different from those in the USA and European countries. The present paper investigates to what extent a model similar to Flath and Nariu (1996) can empirically predict retail densities in Japan and China. The results suggest that the secular decline in the number of retail stores in Japan primarily results from the proliferation of car ownership and the expansion in the average size of a dwelling. We also demonstrate that the model accounts for the large variations in China's retail density.     

An implementation of the HJM model with application to Japanese interest futures

In this paper, we propose a new specification of the forward rate model of Heath, Jarrow and Morton [5] and apply it to the Japanese 3 month interest rate futures. Our empirical result shows that the model we propose can capture the forward interest rate movement.     

Crisis and Creative Destruction: Cases of Korean and Japanese Stock Markets

In this essay, we investigate the contrasting performance of Korean and Japanese stock markets before and after the East Asian currency crisis. The Korean stock markets showed a sharper decline and a faster recovery than the Japanese stock markets. First, we theoretically explain these contrasting movements of stock markets by explicitly modeling and adding some new elements to the idea of IT revolution in Greenwood and Jovanovic (Amer. Econom. Rev. 89, 1999, 116–122). Then we empirically prove that the theoretical model in this paper has some quantitative support by considering the level of monthly stock market capitalization and the return on daily stock index in Korea and Japan.JEL Classification Code: F43     

Secure implementability under Pareto-efficient rules in linear production economies with classical preferences

This paper studies secure implementability (Saijo et al. (2007) “Secure Implementation,” Theoretical Economics 2, pp.203–229) in linear production economies with classical preferences. Although secure implementability is in general stronger than the combination of strategy-proofness and non-bossiness (Satterthwaite and Sonnenschein (1981) “Strategy-Proof Allocation Mechanisms at Differentiable Points,” Review of Economic Studies 48, pp.587–597), this paper shows that both properties are equivalent under Pareto-efficient rules in the economies. In addition, this paper characterizes securely implementable and Pareto-efficient rules in the economies when the number of agents is two.
