Explaining the equity premium in Hong Kong with C-CAPM: The use of emigration growth as an instrument

We test the C-CAPM with CRRA utility using Hong Kong data. In 2SLS regressions, we obtain rather high estimates of the coefficient of relative risk aversion, which could explain the high equity premium in Hong Kong. Because we use lagged emigration growth as an instrument in the first-stage regression, which has significant negative impact on future stock market return in Hong Kong, the first-stage R² and F-statistics are rather high and the weak instrument critique of the validity of 2SLS regressions is potentially resolved. Weak-instrument-robust tests also confirm that the degree of risk aversion is indeed high for Hong Kong.     

Conglomerate Structure and Capital Market Timing

We examine the effects of keiretsu structure on capital market-timing. Keiretsu groups offer a hybrid structure between fully integrated conglomerates and stand-alone firms. We find that past market conditions affect the capital structure of keiretsu firms more than they affect the capital structure of unaffiliated firms. The decision to issue equity is more correlated with market conditions for keiretsu members than it is for unaffiliated firms. The stock returns of keiretsu firms following the issuance of equity decrease with the size of the issuance. These results suggest that keiretsu members time the issuance of equity more so than stand-alone firms.     

The examination of pseudo-allocative and pseudo-overall efficiencies in DEA using shadow prices

The original Data Envelopment Analysis (DEA) models developed by Charnes et al. (Eur J Oper Res 2:429–444, 1978), Banker et al. (Manag Sci 30:1078–1092, 1984) were both radial models. These models and their varied extensions have remained the most popular DEA models in terms of utilization. The benchmark targets they determined for inefficient units are primarily based on the notion of maintaining the same input and output mixes originally employed by the evaluated unit (i.e. disregarding allocative considerations). This paper presents a methodology to investigate allocative and overall efficiency in the absence of defined input and output prices. The benchmarks determined from models based on this methodology will consider all possible input and/or output mixes. Application of this methodology is illustrated on a model of the financial intermediary function of a bank branch network.     

Beyond bureaucracy? Work organization in call centres

Call centres are a rapidly growing, IT-based channel for service and sales delivery, particularly in the financial services and telecom industries. Although little research has been undertaken on the human resource aspects of call centres, two contrasting images are emerging. The first emphasizes the bureaucratic, constraining nature of these work settings, while the second image points towards worker empowerment characteristic of knowledge-intensive settings. Which of these two images more faithfully portrays the nature of work organization in call centres is the subject of our paper. Drawing on qualitative research undertaken in six call centres and a survey of front-line workers, we show that elements of both models coexist and that a hybrid model predominates. The theoretical basis for this contention, and its institutionalization as mass customized bureaucracy, lies in management's on-going attempts to reconcile two conflicting principles: standardization of processes and customization of products. The paper also explores, as key consequences of mass customized bureaucracy, front-line workers' satisfaction with various facets of their job and their overall job satisfaction, in addition to discretionary work effort. Only in relation to job security and co-worker relations could front-line workers be considered satisfied. Overall, these employees were ambivalent in their responses. They were however more likely to give more discretionary work effort than indicated by their extent of satisfaction. We conclude that, although the existing pattern of work organization may be superior to more bureaucratic forms, it is by no means ideal from the standpoint of either front-line workers or management.

War and socialism: why eastern Europe fell behind between 1950 and 1989†

This article reconsiders the relative growth performance of centrally planned economies in the broader context of postwar growth in Europe. It reports a new dataset of revised estimates for investment rates in eastern European countries between 1950 and 1989. Complemented with data on other growth determinants, this evidence is used to re‐evaluate the socialist growth record in a conditional convergence framework with a panel of 24 European countries. After controlling for relative backwardness, investment rates, and improvements in human capital, the findings show that centrally planned economies underperformed due to their relative inefficiency only after the postwar golden age. In the 1950s and 1960s, eastern Europe was falling behind mainly due to relatively low levels of investment and weak reconstruction dynamics. Both are explained, in part, by the lack of labour‐supply flexibility that, in turn, resulted from the comparatively much larger negative impact of the war on population growth in eastern Europe.     

Does timing of decisions in a mixed duopoly matter?

We determine the endogenous order of moves in a mixed price-setting duopoly. In contrast to the existing literature on mixed oligopolies we establish the payoff equivalence of the games with an exogenously given order of moves if the most plausible equilibrium is realized in the market. Hence, in this case it does not matter whether one becomes a leader or a follower. We also establish that replacing a private firm by a public firm in the standard Bertrand?CEdgeworth game with capacity constraints increases social welfare and that a pure-strategy equilibrium always exists.     

Global trade flows and economic policy uncertainty

ABSTRACT

This article investigates the impacts of economic policy uncertainty (EPU) on global trade flows in gauging international trade developments. We employ a global vector autoregressive (GVAR) trade model, augmented with value-added bilateral trade linkages, that allows for quantifying the effects of economy-specific uncertainty shocks on exports and imports of individual economies. We find substantial spatial propagation in the temporal dynamics of international transmission of shocks amidst the manifestations of cross-border global value chains (GVCs) with China’s accession into the WTO. We provide evidence for the significance of EPU of China and the United States, particularly the latter, in influencing global trade flows. Our results show that while the US impacts can largely be attributed to its indirect trade linkages with other economies, the impacts of China can be relegated more to its direct GVC linkages. The findings have implications on trade protectionist inclinations of the current-term US government and the ongoing efforts of China’s policymakers in steering macroeconomic rebalancing for sustainable growth.
