Trade‐related Job Loss,Wage Insurance and Externalities: An Ex Ante Efficiency Rationale for Wage Insurance

The extension of adjustment assistance to those who have suffered trade‐related job displacement is widely supported on both sides of the economics of globalisation debate. The form that such assistance should take, namely wage insurance, is also the subject of wide agreement. Nevertheless, the formal economic rationales offered for such a policy are varied, including political economy arguments, equity arguments and market failure/ex post efficiency arguments. This note proposes an ex ante efficiency‐based rationale for the provision of adjustment assistance in the specific form of wage insurance. Job displacement imposes pecuniary externalities on displaced workers, which, in a complete markets setting, induce only shifts along the ex ante Pareto‐efficient frontier. However, when markets are incomplete, pecuniary externalities become welfare‐relevant. Without the possibility of diversifying or hedging the risk of pecuniary external diseconomies of job displacement using contingent claims, welfare is reduced ex ante. Wage insurance – whether publicly underwritten, privately underwritten (as in Shiller's (2003 ) ‘livelihood insurance’), or supplied on a mixed public/private basis – completes the market for contingent claims, allowing workers to diversify or hedge the risk of trade‐related pecuniary external diseconomies. By facilitating risk sharing, wage insurance removes an impediment to ex ante Pareto efficiency. Moreover, wage insurance affects not only post‐displacement behaviour by increasing the incentive to reacquire employment quickly, but it also affects pre‐displacement consumption and investment behaviour, in particular, lowering the threshold at which workers will be willing to undertake irreversible investment in industry‐specific skills.     

Are Asian stock markets efficient? Evidence from new multiple variance ratio tests

This paper tests for the martingale hypothesis in the stock prices of a group of Asian markets. We use new multiple variance ratio tests based on the wild bootstrap and signs. These are non-parametric finite sample tests, which do not rely on large sample theories for statistical inference. This paper also presents Monte Carlo results that these non-parametric tests show superior small sample properties to those of the conventional Chow–Denning test. Both weekly and daily data from 1990 are considered, while moving sub-sample windows are used for the latter to control the sensitivity of the results to a particular sample period. It is found that the Hong Kong, Japanese, Korean and Taiwanese markets have been efficient in the weak-form. The markets of Indonesia, Malaysia and Philippines have shown no sign of market efficiency, despite financial liberalization measures implemented since the eighties. We have also found evidence that the Singaporean and Thai markets have become efficient after the Asian crisis. In general, the results point toward the notion that the pricing efficiency of a market depends on the level of equity market development as well as the regulatory framework conducive of transparent corporate governance.     

Unanimous subjective probabilities

This note shows that if the space of events is sufficiently rich and the subjective probability function of each individual is non-atomic, then there is a σ-algebra of events over which everyone will have the same probability function, and moreover, the range of this common probability is the entire unit interval.      

National Ownership and Hr Practices In Uk Greenfield Sites

This article reports research on the influence of country of ownership on HR policy and practice in UK establishments. It is hypothesised that establishments will conform to national stereotypes in the practices they adopt and that establishments owned by firms from the USA, Japan and Germany, will, albeit in different ways, adopt more HR practices and report better outcomes than their UK counterparts. the research is based on the Third Workplace Industrial Relations Survey and on a sample of new establishments, opened in the 1980s. Analysis of the data from the 1990 Workplace Industrial Relations Survey finds no evidence that foreign-owned firms are more likely to adopt HR practices. the study of new workplaces finds that UK-owned establishments are as enthusiastic as the foreign-owned in their adoption of HR policy and practice. There is also evidence to support, at least partially, the stereotypes of the American and Japanese approaches. However German-owned establishments do not conform to the expected home country pattern. They are the least likely to adopt HR practices and also report poorer HR and employee relations outcomes. the study challenges the assumption that foreign-owned firms in the UK are more likely to adopt HR practices and indicates that we must be cautious in applying stereotypical national approaches to HRM both among foreign and UK establishments.     

Failure Prediction: Evidence from Korea

This study is an attempt to construct and test a distress classification model for Korean companies. Utilizing a sample of 34 distressed firms from the recent 1990-1993 period and a matched (by industry and year) sample of non-failed firms, we observe the classification accuracy of two models. Both models utilize measures of firm size, asset turnover, solvency and leverage with one model available for testing only on publicly traded companies and one model applicable to all public and private entities. We observe excellent classification accuracy based on data from the first two years prior to distress. And, although the accuracy drops off after t -2, the models still provide effective early warnings of distress in many cases. The results of this study are of particular relevance in the current financial market scenario of increased deregulation and greater individual financial institution decision making. It is somewhat ironic for us to be proposing the use of a financial distress early-warning model given the current robust economic growth and low bankruptcy rate in Korea. But, the financial problems in Japan are a sobering reminder that high growth can be followed by financial excesses, increased business failures and large loan losses.     

Vertical Integration and Competition Policy

Vertical integration can be a source of significant strategic advantage for firms, whether in the form of backward integration to gain security of some important supply or of forward integration to ensure adequate distribution of products or services. It may have profound effects on the competitive processes in an industry, substantially modify the threats from new entrants or substitute products, and mitigate the power of suppliers or buyers. Yet for exactly these reasons, vertical integration causes great concern to competition authorities. A number of consumer products markets with vertical ties have caused such disquiet to the UK's Office of Fair Trading (OFT) in recent years that they have been referred to the Monopolies and Mergers Commission (MMC) for further investigation. These include beer, petrol and soft drinks. The three cases illustrate the nature and importance of the strategic advantage derived from vertical integration. They also illustrate the concern competition authorities feel about vertical integration, and provide lessons for firms regarding the objections that may be raised towards their trading arrangements.     

Nonlinear regression for unit root models with autoregressive errors

This paper shows that the nonlinear least squares estimator for unit root models has the limiting distribution free of nuisance parameters and is more efficient than the augmented Dickey–Fuller estimator when the sum of coefficients for lagged variables is negative.     

Business model schema: business model innovation tool based on direct causal mechanisms of profit

ABSTRACT

Defining business model as the logic/mode/way/framework to seek profit/money and glancing at the evolution of concept business, this paper develops a business model schema (BMS) as a holistic two-dimensions multi-level tool/method for business model innovation (BMI) based on the direct causal mechanisms of profit (DCMP). First, this paper takes DCMP as the logical/theoretical framework by which business model innovation process is identified and specified. And according to that process, it develops a BMS, illustrates an example of BMS to show up its practical usefulness, compares the similarities and differences between BMS and the existing powerful one business model canvas (BMC), and finally asserts that BMS must be a good and useful method in theory and practice because it stands on DCMP that ensures the genuine causality of profit and also it turns out practically useful, recalling the Kurt Lewin’s maxim (1945), “There is nothing so practical as a good theory.
