Competition, Market Structure and Job Turnover

Does internationalization mean increased reallocation of employment among plants and thus higher adjustment costs? This paper studies the reallocation of jobs among plants in the Swedish economy 1986–97 using micro data. It turns out that the rate of job turnover is high in industries with high rates of innovation and employment growth, and low in concentrated industries with limited competition. However, we find no evidence for the view that increased openness to international competition would increase job turnover. In fact turnover is lower in export oriented industries where foreign ownership is frequent.     

Corporate credit risk modeling and the macroeconomy

Despite a surge in the research efforts put into modeling credit and default risk during the past decade, few studies have incorporated the impact that macroeconomic conditions have on business defaults. In this paper, we estimate a duration model to explain the survival time to default for borrowers in the business loan portfolio of a major Swedish bank over the period 1994–2000. The model takes both firm-specific characteristics, such as accounting ratios and payment behaviour, loan-related information, and the prevailing macroeconomic conditions into account. The output gap, the yield curve and consumers’ expectations of future economic development have significant explanatory power for the default risk of firms. We also compare our model with a frequently used model of firm default risk that conditions only on firm-specific information. The comparison shows that while the latter model can make a reasonably accurate ranking of firms’ according to default risk, our model, by taking macro conditions into account, is also able to account for the absolute level of risk.     

Implicit water pricing in Namibian farmland markets

Groundwater can augment total agricultural water supply in areas where rainfall is persistently low, but can also function as a buffer source of water in areas where rainfall is high but variable. In arid countries it is important to examine which of these functions dominates, as this has implications for water policy. As aquifers become depleted, the buffer function can be replaced by other local water supply schemes. However, if groundwater is mainly used to augment total water supply, the only replacement is long-distance supply schemes that may not be economically desirable. This study used Namibian farm price data to estimate implicit water values. The results are consistent with a buffer function for groundwater, but do not show conclusively that this function is more important than other functions. On precautionary principles, one should therefore assume that it will become necessary to decrease agricultural water use as aquifers become depleted.     

The Dilemmas of Tax Coordination in the Enlarged European Union

This study evaluates the economic effects of corporate tax coordinationin the enlarged European Union (EU) using a computable generalequilibrium model. Our main findings are as follows: (i) Corporatetax coordination can yield modest aggregate welfare gains. The2004 enlargement of the EU has increased the potential gainsfrom tax harmonization, provided corporate tax rates and taxbases are harmonized at their unweighted averages. (ii) Allscenarios for coordination leave some EU Member States as winnersand others as losers. An agreement on tax coordination is thereforelikely to require elaborate compensation mechanisms. (iii) Thelarge and diverse country effects suggest that Enhanced Cooperationfor a subset of the Member States may be the most likely routetowards tax coordination. (iv) Identifying winners and losersfrom coordination for the purpose of a compensation mechanismmay be problematic, since countries experiencing gains in GDPand welfare tend to lose tax revenues, and vice versa.

Plural governance: The effect of internal production on supplier performance

We suggest that both making and buying the same product or service has several effects on supplier performance. A model is developed and tested by use of answers gathered from the Danish municipalities. The results support the three hypotheses that (1) the negative effects of technological uncertainty on supplier performance decrease when buyers combine internal production and external sourcing, (2) the negative effects of performance uncertainty on supplier performance decrease when buyers combine internal production and external sourcing, and (3) the negative effects of asset specificity on supplier performance decrease when buyers combine internal production and external sourcing. However, the moderating effects depend on how the plurality is measured. The results indicate that internal production may facilitate effective governance of the relationships with external suppliers. Implications for research on make-or-buy decisions and for practice are also discussed.     

Corporate legitimacy in risk society: the case of Brent Spar

The aim of this paper is to understand what lessons on corporate legitimacy can be drawn from the Shell – Greenpeace conflict in 1995 about the dumping of the Brent Spar oil storage platform in the North-East Atlantic. Based on theories of corporate legitimacy and risk society, it is argued that the Brent Spar conflict reflects a new balance between business, government and civil society as well as a radicalization of the requirements for corporate legitimacy. As a part of these new and more demanding requirements, corporations will need to address a much broader scope of responsibilities and a wider circle of stakeholders than suggested so far by theories of stakeholder management. In addition, corporations will need to develop new and trustworthy forms of dialogue with the public. © 1998 John Wiley & Sons, Ltd and ERP Environment.     

Global restructuring—a place for ecology?

This introductory article summarizes the discussions and results of the Fifth Annual Greening of Industry Conference, Global Restructuring—A Place for Ecology?, held in Heidelberg, Germany, November 25–27, 1997. The Greening of Industry Network is concerned with the transition of industry towards sustainable production as an essential part of achieving a sustainable society. The Network conferences, held at different locations around the world, promote this goal by bringing together participants from different regions and with different backgrounds (academia, industry, governments and NGOs). The conferences are venues for information exchange, learning and dialogue about different aspects of the greening of industry and possible pathways to a sustainable society. © 1997 John Wiley & Sons, Ltd and ERP Environment.     

Energy use in the Namibian economy from 1995 to 1998

As part of a natural resource accounting project being undertaken in Namibia, energy accounts have been compiled and are used to analyse energy use by different economic sectors. Households account for most energy use, especially of traditional fuels, and many households continue to rely on firewood even when they have access to electricity. A new paraffin tax was introduced in 1999, because it was believed that the price differential between diesel (which was already taxed) and paraffin encouraged substitution, but there is little indication that substitution was actually taking place. The policy goal of increasing mines' use of electricity at the expense of fossil fuels appears to have been met during the period studied, but this is entirely due to the problems of one mining company which is expected to resume operations shortly. The results also suggest that there is room for improved efficiency in energy use for water supply, and that instituting measures against theft and non-payment of electricity might save substantial amounts of electricity.     

The Effects of Temporary Exchange-Rate-Based Stabilizations when Money Serves a Productive Role

This paper investigates the effects on production, consumption, and welfare that result from a temporary exchange-rate-based (ERB) stabilization plan. The analysis is based on a dynamic optimizing model of a small open economy where real money is assumed to be a factor that is used in the production of goods. The assumption of money serving a productive role makes the model capable of generating a boom-bust cycle in output, as is often experienced during ERB stabilization plans. It is shown that if the stabilization plan is expected not to be too short and/or the costs associated with the breakdown of the plan are not too high, a temporary decrease in the rate of exchange rate devaluation will increase economic welfare. It is also found that if some of the increase in output in the initial phase of the stabilization plan is saved for periods after the plan has broken down, there is a greater chance that the ERB plan will increase economic welfare. On the other hand, if the plan is not sufficiently credible at the outset, or there is not enough intertemporal transference of output, the stabilization plan is likely to be harmful to economic welfare.

Asymptotic normality of narrow-band least squares in the stationary fractional cointegration model and volatility forecasting

We consider semiparametric frequency domain analysis of cointegration between long memory processes, i.e. fractional cointegration, allowing derivation of useful long-run relations even among stationary processes. The approach is due to Robinson (1994b. Annals of Statistics 22, 515–539) and uses a degenerating part of the periodogram near the origin to form a narrow-band frequency domain least squares (FDLS) estimator of the cointegrating relation, which is consistent for arbitrary short-run dynamics. We derive the asymptotic distribution theory for the FDLS estimator of the cointegration vector in the stationary long memory case, thus complementing Robinson's consistency result. An application to the relation between the volatility realized in the stock market and the associated implicit volatility derived from option prices is offered.
