Labour market implications of EU product market integration

European labour markets are in a state of flux due to the changing market situation induced by international integration. This process affects wage formation through more fierce product market competition and increased mobility of jobs. This development is by some observers taken to enforce labour market flexibility, while for others it signals an erosion of social standards and in turn possibly the welfare society. Since labour is not very mobile in Europe, the effects of international integration on labour markets are mostly indirect via product market integration. We review the channels through which product market integration affects labour markets and perform an empirical analysis of the convergence and interdependencies in wage formation among EU countries. We find that integration is changing labour market structures and inducing wage convergences as well as stronger wage interdependencies, but it is a gradual process. Moreover, the present study does not support the view that international integration will lead to a 'race to the bottom' and rapidly erode domestic labour markets standards, nor that it will relieve politicians of the need to consider labour market reforms to improve labour market performance.     

The Causal Effect of Retirement on Health: Understanding the Mechanisms

This article examines the direct effects of retirement on health, as well as its indirect effects, through a mediation analysis. Using Australian panel data, analysis reveals that changes in retirement status and retirement duration imply positive causal effects on self‐assessed health as well as physical health and mental health. Gender plays an important role in shaping these relationships. For women, the positive relationship between retirement duration and health can be attributed to physical activity. In contrast, men appear to enjoy better health when staying retired for longer because they participate more in outdoor activities.     

Innovation and export activities in the German mechanical engineering sector: an application of testing restrictions in production analysis

Since Solow (Q J Econ 70:65–94, 1956) the economic literature has widely accepted innovation and technological progress as the central drivers of long-term economic growth. From the microeconomic perspective, this has led to the idea that the growth effects on the macroeconomic level should be reflected in greater competitiveness of the firms. Although innovation effort does not always translate into greater competitiveness, it is recognized that innovation is, in an appropriate sense, unique and differs from other inputs like labor or capital. Nonetheless, often this uniqueness is left unspecified. We analyze two arguments rendering innovation special, the first related to partly non-discretionary innovation input levels and the second to the induced increase in the firm’s competitiveness on the global market. Methodologically the analysis is based on restriction tests in non-parametric frontier models, where we use and extend tests proposed by Simar and Wilson (Commun Stat Simul Comput 30(1):159–184, 2001; J Prod Anal, forthcoming, 2010). The empirical data is taken from the German Community Innovation Survey 2007 (CIS 2007), where we focus on mechanical engineering firms. Our results are consistent with the explanation of the firms’ inability to freely choose the level of innovation inputs. However, we do not find significant evidence that increased innovation activities correspond to an increase in the ability to serve the global market.     

Access regulation with asymmetric termination costs

In many telecommunications markets incumbent providers enjoy a demand-side advantage over any entrant. However, market entrants may enjoy a supply-side advantage over the incumbent, since they are more efficient or operate on innovative technologies. Considering both a supply-side and a demand-side asymmetry, the present model analyzes the effect of two regulatory regimes: an access markup for a low cost network and reciprocal charges below the costs of a high cost network. Both regimes may have adverse effects on subscribers, market shares, and profits. It can be shown that an access markup is not generally beneficial and an access deficit not generally detrimental for the respective networks.     

Building a computable general equilibrium tax model for Italy

In this paper, we develop a multi-sectoral computable general equilibrium tax model for Italy allowing for a number of fiscal tools. We illustrate the methodology for modelling and accommodating the full range of direct and indirect taxes into the national general equilibrium model. In particular, we build a commodity tax matrix by commodity, source, user and tax type; and a production tax matrix by industry and tax type. We also put a special emphasis on the institutional sector accounts, incorporating a detailed system of equations. Our model provides a powerful tool for acquiring new insights in fiscal policy analysis, through the assessment of tailored tax reforms, which can consist of either changes in tax rates and tax bases for indirect and direct taxes. Finally, to validate the model we perform an equalizing Value-Added-Tax rates reform. We find that a budget-neutral uniform tax rate reform would be GDP and welfare improving. However, results across agents and sectors vary.     

Improved estimators in some linear errors-in-variables models in finite samples

The paper uses a Monte Carlo study to demonstrate the dominance under mean squared errors or quadratic loss of a new improved estimator for some linear errors-in-variables models in finite samples. The new estimator is non-linear and biased in a conventional sense and has a smaller risk than the least squares and the Stein estimators. Standard errors for this estimator can be conveniently obtained by bootstrapping methods.     

Interest-rate policy and rational expectations

The choice of monetary instrument under rational expectations is discussed in a general equilibrium model for the financial sector. It is shown that a supply rule leads to indeterminate asset prices, whereas the prices are determinate under an appropriately formulated interest-rate policy.     

Attitudes toward foreign assignments among Danish economists

This article addresses attitudinal issues toward foreign assignments and reports on data collected from a distinct sample of respondents—Danish economists. One of the much‐debated questions is whether foreign assignments are becoming less attractive, in particular among the younger employees, who tend to follow more narrow self‐interests and stay home. This is supposed to be reinforced by deteriorating corporate policies (i.e., offers being less attractive). The present study provides the basis for rather significant findings. The economists tend to look quite positively on expatriation (across age, gender, seniority, former foreign assignment, and unemployment), and this finding is supported by the fact that about 25% of the respondents already had experiences with foreign assignment. © 2004 Wiley Periodicals, Inc.
