Creative Destruction and the Rise of Inequality

Common wisdom interprets the rise in inequality of the last two decades as the result of a skill-biased labor demand shift. This explanation does not account for two important observations: (i) within-group inequality has also markedly risen, and (ii) the rise of inequality has been accompanied by a rise of the volatility of earnings. This paper argues that a dual labor market structure, where some workers are paid efficiency-wages can account for the empirical regularities, in the absence of skilled biased technological change. The analysis demonstrates that an unbiased innovation, as well as North–South trade, can contribute to the efficiency wage premium, and thus to wage inequality, by increasing labor turnover.     

Short‐term monitoring of fiscal policy discipline

Under the Maastricht Treaty and the Stability and Growth Pact (SGP), European Union (EU) Member States commit themselves to avoid excessive deficits over 3% of GDP and to pursue the medium‐term objective of budgetary positions close to balance or in surplus. The SGP also provides regulation for the surveillance of budgetary positions. An analysis of tools for the surveillance of budgetary positions is the focus of this paper. In particular, it addresses two open issues in the empirical public finance literature which are crucial for monitoring fiscal policy discipline in the EU. First, the estimation of the structural component of the fiscal balance ratio. Second, the computation, when only annual fiscal data are available, of quarterly budget balance ratios, using relevant information from quarterly measured macroeconomic series. An econometric model that addresses both issues is presented and estimated. Additionally, this modelling framework allows us to answer questions such as: what is the safety margin that will prevent a particular country from reaching, with certain probability, a budget deficit that breaches the 3% upper bound?

R&D personnel and human resource management in multinational companies: between homogenization and differentiation

This paper discusses the impact of globalization processes on models of R&D personnel management in multinational companies operating in Europe. Existing literature focuses on the globalization of R&D activity, on the one hand, and on national systems of innovation, on the other. By contrast, there are few studies of the linkage between the globalization of R&D and its impact on HRM. Drawing on the practices of multinationals in four sectors (pharmaceuticals, chemicals, computer hardware and software), the paper examines whether the hold of national differences in the area of HRM has been significantly weakened in the face of new models of competitiveness and management in multinationals. It focuses on two dimensions: recruitment and mobility. The studies highlight two major trends. The ‘internationalization’ of R&D clearly has effects on HRM models but not as great as might be expected. HRM policies such as recruitment and pay systems continue to be nationally based, reflecting legal and institutional differences. At the same time, in conjunction with new forms of R&D organization such as projects, the standardization of HRM tools may be observed. But this is partial and affects only a limited number of tools, notably individual evaluation.     

Index-futures arbitrage and the behavior of stock index futures prices

This article examines intraday transaction data for S&P500 stock index futures prices and the intraday quotes for theunderlying index. The data indicate that the futures price changesare uncorrelated and that the variability of these price changesexceeds the variability of price changes in the S&P 500index. This excess variability of the futures over the indexremains even after controlling for the nonsynchronous pricesin the index quotes, which induces auto-correlation in the indexchanges. We advance and examine empirically two hypotheses regardingthe difference between the futures price and its theoreticalvalue: that this 'mispricing' increases on average with maturity,and that it is path-dependent. Evidence supporting these hypothesesis presented.     

Mission Congruence and Organization Design: An Empirical Analysis of Childcare Facilities

The paper investigates the relationship between mission congruence and the reliance on incentives and delegation of decision making, using a dataset on 206 childcare centers. We find that mission congruence between childcare teachers and employers is negatively related to the likelihood of reliance on financial incentives and positively related to teacher autonomy. These results support the idea that worker preferences play an important role in the design of organizations.     

Perceived Ubiquity in Mobile Services

Ubiquity has been referred to as one of the most important characteristics of mobile services. In this study, an instrument for the measurement of perceived ubiquity reflecting the benefits derived from continuity, immediacy, portability, and searchability is developed using a multiple-stage approach. In the initial stage, perceived ubiquity is conceptualized through interdisciplinary perspectives as a multidimensional, 32-item eight-factor construct. In the second stage, the original measurement is pretested on a student sample and recalibrated into a 16-item four-factor instrument. In the third stage, general consumers are invited to complete a task in which they are asked to perform a search with a mobile device before rating the measurement items. A confirmatory factor analysis produces a 12-item four-factor instrument. Furthermore, a second-order structure results from a statistical comparison of alternative models through a competing model strategy. In the final stage, we use a scenario method to validate the measurement tool while establishing discriminant, nomological, and known-group validities. The thorough validation results demonstrate the value of our instrument as a measurement tool of perceived ubiquity that is useful in describing the unique nature of mobile devices and predicting differences in user perceptions of mobile services and desktop PC services. Theoretical and managerial implications are discussed, important limitations are recognized and future research directions are suggested.     

Data-snooping biases in tests of financial asset pricing models

Tests of financial asset pricing models may yield misleadinginferences when properties of the data are used to constructthe test statistics. In particular, such tests are often basedon returns to portfolios of common stock, where portfolios areconstructed by sorting on some empirically motivated characteristicof the securities such as market value of equity. Analyticalcalculations, Monte Carlo simulations, and two empirical examplesshow that the effects of this type of data snooping can be substantial.
