The environmental Kuznets curve in a world of irreversibility

This paper develops an overlapping generations model where consumption is the source of polluting emissions. Pollution stock accumulates with emissions but is partially assimilated by nature at each period. The assimilation capacity of nature is limited and vanishes beyond a critical level of pollution. We first show that multiple equilibria exist. More importantly, some exhibit irreversible pollution levels although an abatement activity is operative. Thus, the simple engagement of maintenance does not necessarily suffice to protect an economy against convergence toward a steady state having the properties of an ecological and economic poverty trap. In contrast with earlier related studies, the emergence of the environmental Kuznets curve is no longer the rule. Instead, we detect a sort of degenerated environmental Kuznets curve that corresponds to the equilibrium trajectory leading to the irreversible solution. I would like to thank Alain Venditti, Mabel Tidball, Alain Jean-Marie and Thierry Bréchet for their helpfull comments and suggestions. I am deeply grateful to an anonymous referee whose comments have greatly improved the paper.     

The transmission of business cycles: Lessons from the 2004 enlargement of the EU and the adoption of the euro

This paper evaluates the macroeconomic interdependencies of seven Central and Eastern European Countries (CEECs) with the Euro Area (EA) through trade relationship. We estimate a near‐VAR model and simulate the responses of activity in those CEECs to output shocks for 12 former members of the EA before and after the 2004 enlargement of the European Union. During both periods, empirical results show that spillover effects come through the main economies of the EA: Germany, France and Italy. Furthermore, CEECs were more responsive to output shocks in the EA after 2004 than before (3.3 times more on average). Increases in spillover effects are larger for the three CEECs that adopted the Euro early (Slovenia, Slovakia and Estonia) than the other CEECs but without higher trade intensity with the EA. Our results show that trade effects are positive inside the same currency area but negative for the CEECs without the euro.     

Uncertainty and the macroeconomy: evidence from an uncertainty composite indicator

This article proposes a uncertainty composite indicator (UCI) based on three distinct sources of uncertainty (namely financial, political, and macroeconomic) for the US economy on the period 1985–2015. For that, we use a dynamic factor model, summarizing efficiently six individual uncertainty proxies, namely two macroeconomic and financial uncertainty factors based on the unpredictability, a measure of (micro)economic uncertainty, the implied volatility index, the corporate bond spreads, and an index of economic policy uncertainty. We then compare the effects of uncertainty on economic activity when the UCI is used instead of individual uncertainty proxies in structural VAR models. The interest of our UCI is to synthesize theses effects within one measure of uncertainty. Overall, the UCI was able to account for the most important dynamics of uncertainty which play an important role in business cycles.     

The Bourdieusian Conception of Social Capital: A Methodological Reflection and Application

This paper is on social capital and the meaning that Bourdieu has given to this concept in his Notes provisoires, published in 1980. He considered social capital as one of the most important forms of capital, along with economic capital and cultural capital. Even though he did not propose an explicit measure of social capital, so it remained in a conceptual state, he promoted an innovative research programme. Our contribution is to propose a generic method to empirically measure and test hypotheses on social capital, based on Bourdieu's work. We aim at creating an analytical framework that places this concept at the centre of the Bourdieusian theoretical approach. For this purpose, we combine two sociological tools that relate to two different sociological traditions, namely social network analysis and multiple correspondence analyses. Thus, our paper describes the ways to combine field and network analyses, and illustrates this with an empirical study.     

Towards Multilife Marketing: How Goods Multiple Lives Practices Create Value for Consumers

Goods multiple lives practices (GMLPs) encompass a wide range of diverse practices that extend product lifecycles. We propose that it is through a holistic consideration of the concept that it is possible to understand its breadth and scope as well as its potential consequences in terms of increased value for consumers. Through 15 in-depth interviews and secondary data analysis, this study explores the value-creating potential of GMLPs for consumers. The results suggest that these practices are based upon three key dimensions to create perceived value for consumers: polymorphous exchanges, protean intermediation, and multichannel structuration.     

A Monte Carlo filtering application for systematic sensitivity analysis of computable general equilibrium results

ABSTRACT

Parameter uncertainty has fuelled criticisms on the robustness of results from computable general equilibrium models. This has led to the development of alternative sensitivity analysis approaches. Researchers have used Monte Carlo analysis for systematic sensitivity analysis because of its flexibility. But Monte Carlo analysis may yield biased simulation results. Gaussian quadratures have also been widely applied, although they can be difficult to apply in practice. This paper applies an alternative approach to systematic sensitivity analysis, Monte Carlo filtering and examines how its results compare to both Monte Carlo and Gaussian quadrature approaches. It does so via an application to rural development policies in Aberdeenshire, Scotland. We find that Monte Carlo filtering outperforms the conventional Monte Carlo approach and is a viable alternative when a Gaussian quadrature approach cannot be applied or is too complex to implement.     

The Distribution of Earnings in an Equilibrium Search Model with State‐Dependent Offers and Counteroffers*

We construct an equilibrium job search model with on‐the‐job search in which firms implement optimal‐wage strategies under full information in the sense that they leave no rent to their employees and counter the offers received by their employees from competing firms. Productivity dispersion across firms results in wage mobility both within and across firms. Workers may accept wage cuts to move to firms offering higher future wage prospects. Equilibrium productivity dispersion across ex ante homogeneous firms can be endogenously generated. Productivity dispersion then generates a nontrivial wage distribution which is generically thin‐tailed, as typically observed in the data.     

Ecological responsiveness and business performance: Four scenarios of compatibility and a multi-faceted strategies framework

This paper investigates the link between business actors' perceptions of the compatibility between ecological responsiveness and business performance and the level of corporate commitment to address ecological issues. The dichotomy between peripheral (or symbolic) actions and embedded (or substantive) actions traditionally assumed in business research arguably reflects a limited conceptualisation of the link between ecological responsiveness and business performance. It fails to exhaustively explain how companies create, maintain, or disrupt practices that affect the natural environment. Combining insights from a conceptual framework that encompasses four scenarios of compatibility (trade-off, ambidexterity, synergy, and symbiosis) and 50 interviews with 25 management consultants, the results show that perceptions of compatibility are associated with a valence of business responses towards either maturation strategies (accommodative, philanthropic, progressive, and consolidative) or minimalistic strategies (lackadaisical, compliance, opportunistic, and cosmetic). The findings bring greater nuance to key forms of corporate ecological responsiveness, and how business agents' interpretations play a key role in shaping a firm's activities in this domain.     

The Challenges for Labour Market Policy during the COVID-19 Pandemic*

The COVID-19 pandemic is having a dramatic economic impact in most countries. In the UK, it has led to sharp falls in labour demand in many sectors of the economy and to initial acute labour shortages in other sectors. Much more than in a typical downturn, the current crisis is not simply a general slowdown in economic activity but also a radical short-term shift in the mix of economic activities – of which an unknown, but possibly significant, amount will be persistent. The initial policy response has focused on cushioning the blow to families’ finances and allowing the majority of workers and firms to resume their original activities once the crisis subsides. These are crucial priorities. But there should also be a focus on reallocating some workers, either temporarily if working in shut-down sectors or permanently by facilitating transitions to sectors and jobs offering better prospects and facing labour shortages. The phasing-out of the furlough subsidies, which is projected to happen in Autumn 2020, brings this into even sharper focus since the alternative for many workers will be unemployment. Active labour market policy will need to be front and centre.
