Exchange rate volatility and regime change: A Visegrad comparison

We analyze exchange rate volatility in the Visegrad Four countries during the period in which they abandoned tight regimes for more flexible ones. We account for path dependency, asymmetric shocks, and movements in interest rates. In addition, we allow for a generalized error distribution. The overall findings are that path-dependent volatility has a limited effect on exchange rate developments and that the introduction of floating regimes tends to increase exchange rate volatility. During the period of flexible regimes, volatility was mainly driven by surprises. Asymmetric effects of news tend to decrease volatility under the floating regime. Interest differentials impact exchange rate volatility contemporaneously under either regime, although we find no intertemporal effect of interest differentials.

Spillovers from foreign direct investment and firm growth: technological,financial and market structure effects

This article examines spillover effects from inward investment on domestic firm growth in the case of a developed host country. The emphasis is placed on the role of the technological gap between domestic and foreign firms in identifying the importance of technology diffusion from the presence of multinationals. An augmented production function is employed to account for technological, financial and market structure effects. Based on a sample of 2589 manufacturing firms operating in Greece between 1992 and 1997, the analysis provides evidence that the significance of spillovers varies with the relative technological position of domestic firms and is higher in the middle and upper quantiles of the growth distribution. It was estimated that a unit increase in the foreign presence in Greek industry raises output growth by 7% on average, in a five‐year period, after controlling for technological differences among firms. This result is consistent with the ‘absorptive capacity’ hypothesis that the technological capability of the host country relates positively to FDI spillover benefits.     

Determinants of the Use of Advanced Technologies

There is an extensive literature about the influences on the adoption of new technologies. However, while we often assert the role of qualifications and skills in the innovation and diffusion processes, there has been little formal econometric work in this area. One of the key reasons for this is the lack of information about human capital in firm accounts, at all levels of the organisation, including the top executive and board of directors. This paper draws on a large, firm level data set to explore the linkages between the adoption and use of 13 advanced technologies and the qualification and skill structure of the enterprise. In addition, it provides a number of further insights about the effects of ownership, firm size and industry structure.     

Two-earner households and housing demand: The effect of the wife's occupational choice

This article analyzes the impact of the occupational choice of married women in two-earner households on the level of housing expenditures. In recent years married women have chosen professional and managerial occupations with increasing frequency. Because entry and exit from such occupations is costly, households will tend to view the incremental income as permanent. To analyze the housing market impact of this trend, a housing expenditure function is estimated using a national data set for the 1979 to 1987 period. The results indicate that households in which the wife is employed in a professional or managerial occupation spend considerably more on housing for given levels of current income. Furthermore, the effect is most pronounced among move-up homebuyers. To the extent that recent trends in female occupational choice continue, the impact on the housing market may be substantial.     

A qualitative analysis of factors associated with user acceptance and rejection of a new workplace information system in the public sector: a conceptual model

This study examines the factors that lead employees to endorse or resist the introduction of a new information system (IS). Findings suggest that attitudes toward adopting IS are related to psychological characteristics of the potential adopters, including, open‐mindedness, self‐efficacy, interest in the information and communication technology, and time remaining before retirement. Also figuring prominently in influencing attitudes are the end‐users' perceptions and expectations with respect to project management, IS quality, IS usefulness, and its effects on organizational positions, work organization, performance, skills, jobs, and worker health. Finally, user attitudes also relate to features of change management practices, including leadership, training, support, recognition, communication, and participation. An integrative conceptual model of IS user adoption is proposed and suggestions for future research are offered. Copyright © 2008 ASAC. Published by John Wiley & Sons, Ltd.

跨国公司国际研发的新趋势与发展中国家的对策

跨国公司作为全球经济的发动机，依然是国际研发的主体。但是，随着经济全球化的不断深入发展，跨国公司的国际研发也出现了新的发展趋势，跨国公司在发展中国家的研发投入日益增加，给发展中国家带来了机遇和挑战。本文认为，发展中国家在积极吸引跨国公司研发投资的同时，应该趋利避害，发展本国的经济。     

Liquidity and Twin Crises

This paper proposes a simple analytical framework for understanding 'twin crises'– i.e. crises where a currency crisis and banking crisis occur simultaneously and reinforce each other. The distinguishing feature of such crises is the spill‐over effects across financial institutions through collateral constraints, declines in market values of assets, currency mismatches on the balance sheet and the endogenous amplification of financial distress through asset sales. We explore the role of liquidity and the role of monetary policy in such crises. In particular, a central question is whether raising interest rates in the face of a twin crisis is the appropriate policy response. Raising interest rates has two countervailing effects. Holding the domestic currency becomes more attractive (other things being equal), but the value of the domestic banking system falls due to the fall in asset prices. When assets are marked to market, there is a potential for endogenously generated financial distress that leads to a collapse of asset prices, as well as the exchange rate. It is thus possible that raising interest rates can have the perverse effect of exacerbating both the currency crisis and the banking crisis.
