Abstract The aim of this paper is to investigate the links between oil prices and various macroeconomic and financial variables for a large set of countries, including both oil‐importing and oil‐exporting countries. Both short‐run and long‐run interactions are analysed through the implementation of Granger‐causality tests, evaluation of cross correlations between the cyclical components of the series in order to identify lead/lag relationships and cointegration analysis. Our results highlight the existence of various relationships between oil prices and macroeconomic variables and, especially, an important link between oil and share prices on the short run. Turning to the long run, numerous long‐term relationships are detected, the Granger‐causality generally running from oil prices to the other variables. An important conclusion is relating to the key role played by the oil market on stock markets.

This article analyses the interactions between various dimensions of corporate social responsibility (CSR) that mediate the relationship between CSR and financial performance. We hypothesize that the absence of consensus in the empirical literature on the CSR–financial performance relationship may be explained by the existence of synergies (complementarity) and trade-offs (substitutability) between the different CSR components. We investigate such relationship using a final unbalanced panel sample of 1094 observations (around 300 firms per year) from 15 countries over the 2002–2007 period. Our results show that responsible behaviours towards employees (human resources dimension) and towards customers and suppliers (business behaviour dimension) appear as complementary inputs of financial performance, indicating mutual benefits and less conflict between those stakeholders. Conversely, responsible behaviours towards customers and suppliers and towards the environment appear as substitutable inputs of financial performance, suggesting more conflict between or over-investment towards those stakeholders.

In this paper we evaluate the respective effects of demographic change, changes in morbidity and changes in practices on growth in health care expenditures. We use microdata, i.e. representative samples of 3441 and 5003 French individuals observed in 1992 and 2000. Our data provide detailed information about morbidity and allow us to observe three components of expenditures: ambulatory care, pharmaceutical and hospital expenditures. We propose an original microsimulation method to identify the components of the drift observed between 1992 and 2000 in the health expenditure age profile. On the one hand, we find empirical evidence of health improvement at a given age: changes in morbidity induce a downward drift of the profile. On the other hand, the drift due to changes in practices is upward and sizeable. Detailed analysis attributes most of this drift to technological innovation. After applying our results at the macroeconomic level, we find that the rise in health care expenditures due to ageing is relatively small. The impact of changes in practices is 3.8 times larger. Furthermore, changes in morbidity induce savings which more than offset the increase in spending due to population ageing.

Abstract. In this paper, we present an overview of a number of issues relating to the equilibrium exchange rates of transition economies of the former soviet bloc. In particular, we present a critical overview of the various methods available for calculating equilibrium exchange rates and discuss how useful they are likely to be for the transition economies. Amongst our findings is the result that the trend appreciation usually observed for the exchange rates of these economies is affected by factors other than the usual Balassa–Samuelson effect, such as the behaviour of the real exchange rate of the open sector and regulated prices. We then consider three main sources of uncertainty relating to the implementation of an equilibrium exchange rate model, namely: differences in the theoretical underpinnings, differences in the econometric estimation techniques, and differences relating to the time‐series and cross‐sectional dimensions of the data. The ensuing three‐dimensional space of real misalignments is probably a useful tool in determining the direction of a possible misalignment rather than its precise size.

The aim of this article is to investigate the link between currency misalignments and economic growth. Relying on panel cointegration techniques, we calculate Real Exchange Rate (RER) misalignments as deviations of actual RERs from their equilibrium values for a set of advanced and emerging economies. Estimating Panel Smooth Transition Regression (PSTR) models, we show that RER misalignments have a differentiated impact on economic growth depending on their sign: whereas overvaluations negatively affect economic growth, RER undervaluations significantly enhance it. This result indicates that undervaluations may drive the exchange rate to a level that encourages exports and promotes growth.

This paper introduces a kernel-based nonparametric inferential procedure to test for Granger-causality in distribution. This test is a multivariate extension of the kernel-based Granger-causality test in tail-event introduced by Hong et al. (2009) and hence shares its main advantage, by checking a large number of lags with higher order lags discounted. Besides, our test is highly exible as it can be used to check for Granger-causality in specific regions on the distribution supports, like the center or the tails. We prove that it converges asymptotically to a standard Gaussian distribution under the null hypothesis and thus it is free of parameter estimation uncertainty. Monte Carlo simulations illustrate the excellent small sample size and power properties of the test. This new test is applied for a set of European stock markets in order to analyse the spill-overs during the recent European crisis and to distinguish contagion from interdependence effect.

Abstract This paper examines empirically the interaction between immigration and host country economic conditions. We employ panel vector autoregression (VAR) techniques for a large annual data set on 22 OECD countries over the period 1987–2009. The VAR approach addresses the endogeneity problem by allowing for endogenous interactions between the variables in the system. Our results provide evidence of migration contribution to host economic prosperity (positive impact on GDP per capita and negative impact on aggregate unemployment, native‐ and foreign‐born unemployment rates). We also find that migration is influenced by host economic conditions (migration responds positively to host GDP per capita and negatively to host total unemployment rate).

We use a price-based methodology to assess the global energy-return-on-investment (EROI) of coal, oil, and gas, from the beginning of their reported production (respectively 1800, 1860, and 1890) to 2012. It appears that the EROI of global oil and gas productions reached their maximum values in the 1930s–40s, respectively around 50:1 and 150:1, and have declined subsequently. Furthermore, we suggest that the EROI of global coal production has not yet reached its maximum value. Based on the original work of Dale et al. (2011), we then present a new theoretical dynamic expression of the EROI. Modifications of the original model were needed in order to perform calibrations on each of our price-based historicalestimates of coal, oil, and gas global EROI. Theoretical models replicate the fact that maximum EROIs of global oil and gas productions have both already been reached while this is not the case for coal. In a prospective exercise, the models show the pace of the expected EROIs decrease for oil and gas in the coming century. Regarding coal, models are helpful to estimate the value and date of the EROI peak, which will most likely occur between 2025 and2045, around a value of 95(±15):1.

This paper aims to evaluate the economic and fiscal effects of inflows of asylum seekers into Western Europe from 1985 to 2015. It relies on an empirical methodology that is widely used to estimate the macroeconomic effects of structural shocks and policies. It shows that inflows of asylum seekers do not deteriorate host countries' economic performance or fiscal balance because the increase in public spending induced by asylum seekers is more than compensated for by an increase in tax revenues net of transfers. As asylum seekers become permanent residents, their macroeconomic impacts become positive.

Measures of the direction and strength of the interdependence among time series from multivariate systems are evaluated based on their statistical significance and discrimination ability. The best-known measures estimating direct causal effects, both linear and nonlinear, are considered, i.e., conditional Granger causality index (CGCI), partial Granger causality index (PGCI), partial directed coherence (PDC), partial transfer entropy (PTE), partial symbolic transfer entropy (PSTE) and partial mutual information on mixed embedding (PMIME). The performance of the multivariate coupling measures is assessed on stochastic and chaotic simulated uncoupled and coupled dynamical systems for different settings of embedding dimension and time series length. The CGCI, PGCI and PDC seem to outperform the other causality measures in the case of the linearly coupled systems, while the PGCI is the most effective one when latent and exogenous variables are present. The PMIME outweighs all others in the case of nonlinear simulation systems.

Context. The first Gaia Data Release contains the Tycho-Gaia Astrometric Solution (TGAS). This is a subset of about 2 million stars for which, besides the position and photometry, the proper motion and parallax are calculated using Hipparcos and Tycho-2 positions in 1991.25 as prior information. Aims. We investigate the scientific potential and limitations of the TGAS component by means of the astrometric data for open clusters. Methods. Mean cluster parallax and proper motion values are derived taking into account the error correlations within the astrometric solutions for individual stars, an estimate of the internal velocity dispersion in the cluster, and, where relevant, the effects of the depth of the cluster along the line of sight. Internal consistency of the TGAS data is assessed. Results. Values given for standard uncertainties are still inaccurate and may lead to unrealistic unit-weight standard deviations of least squares solutions for cluster parameters. Reconstructed mean cluster parallax and proper motion values are generally in very good agreement with earlier Hipparcos-based determination, although the Gaia mean parallax for the Pleiades is a significant exception. We have no current explanation for that discrepancy. Most clusters are observed to extend to nearly 15 pc from the cluster centre, and it will be up to future Gaia releases to establish whether those potential cluster-member stars are still dynamically bound to the clusters. Conclusions. The Gaia DR1 provides the means to examine open clusters far beyond their more easily visible cores, and can provide membership assessments based on proper motions and parallaxes. A combined HR diagram shows the same features as observed before using the Hipparcos data, with clearly increased luminosities for older A and F dwarfs.

Previous literature has identified oil and gas prices as being the main drivers of CO2 prices in a univariate Generalized Autoregressive Conditional Heteroscedasticity (GARCH) econometric framework (Alberola et al., 2008; Oberndorfer, 2009). By contrast, we argue in this article that the interrelationships between energy and emissions markets shall be modelled in a Vector Autoregressive (VAR) and Multivariate GARCH (MGARCH) framework, so as to reflect the dynamics of the correlations between the oil, gas and CO2 variables overtime. Using the Baba–Engle–Kraft–Kroner (BEKK), Constant Conditional Correlation (CCC) and Dynamic Conditional Correlation MGARCH (DCC-MGARCH) models on daily data from April 2005 to December 2008, we highlight significant own-volatility, cross-volatility spillovers, and own persistent volatility effects for nearly all markets, indicating the presence of strong Autoregressive Conditional Heteroscedasticity (ARCH) and GARCH effects. Besides, we provide strong empirical evidence of time-varying correlations in the range of [−0.3; 0.3] between oil and gas, [−0.05; 0.05] between oil and CO2, and [−0.2; 0.2] between gas and CO2, that have not been considered by previous studies. These findings are of interest for traders and utilities in the energy sector, but also for a broader applied economics audience.

We investigate the impact of new work practices and information and communication technologies (ICT) on working conditions in France. We use a unique French dataset providing information on individual workers for the year 1998. New work practices include the use of quality norms, job rotation, collective discussions on work organization, and work time flexibility. Working conditions are captured by occupational injuries as well as indicators of mental strain. We find that individuals working under the new practices face greater mental strain than individuals who do not. They also face a higher probability of work injuries, at least for benign ones. In contrast, our results suggest that ICT contribute to make the workplace more cooperative and to reduce occupational risks and injuries.

This document describes and discusses a new supply side framework that quantifies the impact of structural reforms on per capita income in OECD countries. It obtains the overall macroeconomic reform impacts by aggregating over the effects on physical capital, employment and productivity through a production function. On the basis of reforms defined as observed changes in policies, the paper finds that product market regulation has the largest overall single policy impact five years after the reforms. But the combined impact of all labour market policies is considerably larger than that of product market regulation. The paper also shows that policy impacts can differ at different horizons. The overall long-term effects on GDP per capita of policies transiting through capital deepening can be considerably larger than the 5- to 10-year impacts. By contrast, the long-term impact of policies coming only via the employment rate channel materialises at shorter horizon.

As the financial crisis reached its climax in September 2008, the most important figure on the planet was Federal Reserve chairman Ben Bernanke. The whole financial system was collapsing, with little to stop it. When a senator asked Bernanke what would happen if the central bank did not carry out its rescue package, he replied, "If we don't do this, we may not have an economy on Monday." What saved finance, and the Western economy, was fiscal and monetary stimulus – an influx of money, created ad hoc. It was a strategy that raised questions about the unexamined nature of money itself, an object suddenly revealed as something other than a neutral signifier of value. Through its grip on finance and the debt system, money confers sovereign power on the economy. If confidence in money is not maintained, crises follow. Looking over the last 5, 000 years, Michel Aglietta explores the development of money and its close connection to sovereign power. This book employs the tools of anthropology, history and political economy in order to analyse how political structures and monetary systems have transformed one another. We can thus grasp the different eras of monetary regulation and the crises capitalism has endured throughout its history.

This paper seeks to understand the drivers of country-level multi-factor productivity (MFP) with a special emphasis on product and labour market policies and the quality of institutions. For a panel of OECD countries, we find that anticompetitive product market regulations reduce MFP levels and that higher innovation intensity and greater openness result in higher MFP. We also find that the impact of product market regulations on MFP may depend on the level of labour market regulations. Better institutions, a more business friendly environment and lower barriers to trade and investment amplify the positive impact of R&D spending on MFP. Finally, we also show that cross-country MFP variations can be explained to a considerable extent by cross-country variation in labour market regulations, barriers to trade and investment and institutions.

Employees who work in complex environments are often evaluated by their supervisors. Data on these evaluations promise to be valuable for analyzing career dynamics and human resources practices. However, existing literature on subjective evaluations is based on data from individual firms. Furthermore, how supervisors evaluate workers and how firms use these evaluations might vary substantially with context, precisely because these evaluations are subjective. Thus, little is known regarding whether findings from single-firm studies generalize to broader settings. We examine personnel data from six large companies and establish how subjective performance ratings correlate with objective career outcomes. We find many similarities across firms in how these ratings correlate with base pay, bonuses, promotions, demotions, separations, quits, and dismissals and cautiously propose these as empirical regularities.
