General equilibrium impact of an energy-saving policy in the public sector

We analyse a disregarded environmental policy instrument: a switch in government expenditure away from energy (or other natural resources) and toward a composite good which includes energy-saving expenditure. We first develop two variants of an analytical general equilibrium model. A composite good is produced with constant returns to scale, and energy is imported or produced domestically with diminishing returns, yielding a differential rent to its owners. The government purchases energy and composite goods from private firms. Such a policy unambiguously increases employment. It also raises private consumption and welfare under two conditions: (i) it is not too costly and (ii) the initial share of the resource is smaller in public spending than in private consumption, or the difference is small enough. We then run numerically a model featuring both importation and domestic production of energy (oil, gas and electricity), for the OECD as a whole. Simulations show that employment, welfare and private consumption rise. We provide magnitudes for different parameter values.

The Euro Effect on Eurozone Exports

In this article, we examine the impact of the real effective exchange rate for several countries in the Euro area over the period before and after the introduction of the euro. Based on ARDL modeling techniques, we estimate the long-run and short-run relationships between exports volumes and a number of key variables, namely Real Effective Exchange Rate, weighted GDP and Output Gap. This article is particularly oriented towards the study of long-term relationships between the exchange rate and global exports performance, on the one hand; and between exchange rates and intra-European exports performance, on the other. Two measures of exchange rate are considered: a global real exchange rate to investigate the impact of exchange rates on overall exports and an intra European real exchange rate calculated to detect its effect on intra-European trade. The study shows that there is a big difference between the impact of exchange rates on exports before and after the establishment of the European Monetary Union on the one hand, and between the impacts of exchange rates on intra-European global exports on the other hand.     

Dual Job Holding and the Gig Economy: Allocation of Effort across Primary and Gig Jobs

This article explored motivations for allocating effort between “gig” and primary jobs using a sample of Amazon Mechanical Turk workers. We found that main job hour constraints, a commonly cited rationale for traditional moonlighting, were a motivation for men but not for women. Other factors affecting effort were also gender specific: Men were driven to spend more time on gig jobs to increase their incomes, while women were motivated by insecurity in their main job. Women, though not men, who were more depressed based on the Center for Epidemiologic Studies Depression scale earned less in their gig economy job. Finally, higher risk aversion reduced income from gig work for men, but not women. We concluded that motivations for effort allocated between the primary and gig jobs differ from those identified in past literature as important for traditional moonlighting decisions.     

Foreign Banks and Credit Volatility: The Case of Latin American Countries

The number of foreign banks in Latin America increased substantially over the period 1995–2001, prompting a debate on the potential consequences for host countries. Discussions focused on efficiency, the impact on competition and product market diversification in the banking industry, and the quality of the regulatory environment, among other issues. Against this background, this paper uses ARCH techniques to test the impact of foreign banks on both the level and the volatility of real private bank credit in a panel of eight Latin American countries, using quarterly data over the period 1995–2001. The empirical findings show that, together with financial development, the presence of foreign banks has contributed to reducing real credit volatility, improving the buffer shock function of the banking sector.
