On the frequency of wage indexation

This paper analyzes the optimal frequency of wage indexation. It demonstrates that a change in the expected value of money does not affect the optimal frequency, but that an increase in the riskiness of the value of money leads to an increase in the optimal frequency. An increase in the worker's risk aversion also leads to an increase in the optimal frequency, while an increase in the cost of indexation leads to a decrease in the optimal frequency.     

Collective bargaining and regional wage differences in Spain: an empirical analysis

This article analyses the importance of labour market institutions and, in particular, collective wage bargaining in shaping regional wage differences in the Spanish labour market. Using microdata from the Spanish Structure of Earnings Survey, our results reveal that there are significant inter-regional wage differences for similarly skilled workers. These differences are present throughout the whole wage structure and can be explained by both competitive and non-competitive factors, such as insufficient competition in product markets. In this context, industry-level collective bargaining plays a major role in accounting for regional wage differences, a role that in the Spanish case is enhanced due to its unusual regional dimension.     

The effects of indexation of wage contracts on macro-economic stability

The paper develops a simple analytical framework in which the shortrun affects of wage indexation on the dynamic stability of inflation can be analyzed. It consists of a unlonized labor market faced by a competitive demand. Without indexation, the wage contract is based upon the union's prediction of the price level during the period of the contract. With indexation, the same objective is achieved by contracting only once at some initial period, subject to the stipulation that the nominal wage is linked to the price level. The main result is that when the demand for money is sensitive to changes in the expected rate of inflation, nominal variables like prices and wages are more likely to yield an unstable dynamic response with wage indexation, thus endangering the monetary system.     

Immigration and domestic wage: an empirical study on competition among immigrants

While studies on the wage effects of immigration focus on native workers, there is significantly less information on the wage effects of immigration on domestic foreign-born workers. In addition to analysing the impact of immigration on wages of native workers, in this article, we estimate the internal competition among foreign-born workers in the United States. Firstly, using data from the Current Population Survey, we find no empirical evidence supporting the substitutability of native workers for immigrants. Secondly, there is no statistical difference between skilled and unskilled immigrants on the influence of the domestic labour market outcomes. Finally, there is no internal competition among immigrants. The income of non-citizen workers mainly depends on state and national levels of economic situations, not the number of non-citizen workers available in the labour market.     

The competitive and anticompetitive aheories of advertising: an empirical analysis

Pairs trading is a popular dollar-neutral trading strategy. This article, using the components of the S&P 500 index, explores the performance of a pairs trading system based on various pairs selection methods. Whereas large empirical applications in the literature focus on the distance method, this article also deals with well-known statistical and econometric techniques such as stationarity and cointegration which make the trading system much more demanding from a computational point of view. Trades are initiated when stocks deviate from their equilibrium. Our results confirm, after controlling for risk and transaction costs, that the distance method generates insignificant excess returns. While a pairs selection following the stationarity criterion leads to a weak performance, this article reveals that cointegration provides a high, stable and robust return.     

An explorative empirical analysis of the influence of labour flows on wage formation

This study presents an explorative econometric analysis of the influence of labour market flows on wage formation. It applies the vector cointegration and common trends methodology of Johansen (Likelihood-based Inference in Cointegrated Vector Autoregresssive Models, OUP, Oxford, 1995). According to this approach, a combination of the flow of layoffs (flow from employment to unemployment) and the flow of filled vacancies (successful matches) appears to be an adequate alternative to the unemployment rate as indicator of labour market tightness in the wage equation for The Netherlands.     

Coordination and price shocks: an empirical analysis

This paper outlines a new technique, which makes optimal control in a stochastic minimum variance framework computationally feasible. The new approach is then used to evaluate gains to policy coordination in the context of a macroeconometric model for the G-3. More specifically, we consider policy responses to a temporary price shock in a single country and in multi-country cases. The results show that coordination brings about a striking improvement in the overall control of inflation and a reduction in output costs.     

Prostitution services: an exploratory empirical analysis

This study provides an empirical analysis of the market for some male prostitution services in the UK. Flexible working hours, part-time working, and multiple job holding are considered as important labour market characteristics in this service sector. Statistical models helping explain the provision of a deviant and a more mainstream sexual service is reported, utilizing cross-section data drawn from individual prostitute advertisements. The significance of various declared intrinsic endowments of the prostitutes are examined in relation to the offer of these services, including age, ethnicity, physique, and masculine demeanour.     

Temporary employment and segmentation in the Spanish labour market: An empirical analysis through the study of wage differentials

We aim to add empirical evidence to the already studied field of wage differentials between temporary and permanent workers in Spain. Our goal is to find out which determinants of wage differentials are relevant when explaining such differences. Furthermore, the endogeneity of such feature (the type of contract) is controlled for. The same exercise is done with two data sets: the ECHP and the Structure of Earnings Survey. Results show that wage differentials between temporary and permanent workers are explained by the differences in the distribution of personal and job characteristics in both groups, but not by differences in the rewards for those characteristics. These results remain mostly unchanged during the second part of the 1990s, using information from five waves of the ECHP, and are robust to different changes in the econometric specification.JEL Classification: J31, J41The authors would like to thank the participants in the 3rd Summer School of Labour Economics (organised by IZA in Amersee, Munich), in a seminar in the University of Alcalá and in another seminar in the European University Institute in Florence and especially Alison Booth, Luis Toharia, Juan F.

Financial system and technological catching-up: an empirical analysis

This paper explores the role of the financial system in technological catching-up in the expectation that financing mechanisms affect the production and the exports of new or “new to the market” commodities. We have developed indices of related export variety (REV) and of unrelated export variety (UEV) by using the informational entropy function for a sample of 97 countries using NBER & UN trade data for the period 1992–2005. We used these indices sequentially as dependent variables with the bank credit ratio and stock market capitalization ratio as independent variables. In addition, we include the education system, natural resources and four principal component factors characterizing the cost of doing business, political system, quality of governance and the degree of openness of the countries as control variables in our regressions. Our pooled regression models show that the financial system is an important determinant of both types of export variety for all countries but that, for the most successful developers, the banking system and the stock market play different roles, with the former being relatively more appropriate for REV and the latter for UEV. Such specialization of different forms of the financial system seems to confirm that stock markets are likely to be relatively more appropriate to fund the exploratory type of innovations which are required to increase UEV.     

The effects of economic freedom on FDI inflows: an empirical analysis

There is a regular emphasis on the significant role of inward Foreign Direct Investment (FDI) in promoting economic growth. This favourable relationship has induced many governments to adopt policies intended to increase FDI inflows and, thereby, to create conducive business and economic conditions for Multinational Enterprises (MNEs). This paper examines the effects of Economic Freedom (EF) and its sub-components reflecting the Quality of Institutions (QIs) on FDI inflows, using indices derived from the Fraser Institute and from the Heritage Foundation. The empirical analysis is carried out for a panel dataset using different econometric methodologies and empirical specifications. The results underline positive effects of EF on FDI inflows. They reveal that EF sub-components have varying impacts on FDI inflows, where rule of law, market openness, and less-restrictive regulatory environment stand out as the major FDI-promoting institutional factors. Also, there is an empirical evidence that the effects of EF sub-components on FDI inflows exhibit variations through the economic characteristics of the host countries and across geo-economic regions. The results suggest that governments should pursue EF-improving policies, which should be tailored according to the economic and geo-economic characteristics of the host countries, to increase FDI inflows.     

The organizational goal and work effort: an efficiency wage model

This paper sets up an efficiency wage model which combines goal-attainment theory and the expectancy-valence approach. Taking account of the psychological work motivation, we find that the aspiration for goal attainment may be a substitute for unemployment as an instigator of work motivation in full employment. In addition, since raising the firm’s goal has a diverse impact on the high and low need-for-achievement workers, a higher goal-setting does not appear capable of increasing worker effort within firms. This finding reconciles the conflicting experimental results in industrial psychology literature.

Taxing capital flows: an empirical comparative analysis

Recent studies have analysed the impact of capital account opening on income growth, implicitly assuming that the various forms of foreign savings have similar effects. In fact, theoretical considerations suggest that the individual components of private capital inflows have different effects on growth. This paper analyses the link between income growth and private capital inflows. It presents system GMM estimates with annual observations from 1985 to 1996 for 72 countries. When full-sample results are checked for country and period changes, most of capital inflow series lose their ability to explain income growth. Bank flows stand as the sole source of foreign financing that displays a positive and robust correlation with growth.     

The labour market and the distribution of earnings: an empirical analysis for Italy

Using four waves of data from the Participation Labour Unemployment Survey, a database of information on the Italian labour market supply, we address the question of earnings dispersion by applying a ‘nested’ decomposition procedure of the Theil inequality measure, which combines into a unified framework the standard decompositions by population subgroups and income sources. The empirical evidence obtained points to the key role played by the self-employees in shaping labour income inequality, especially at the upper extreme of the earnings distribution, and the emergence of non-standard forms of employment as an important feature of the contemporary workplace.
