Renewable energy consumption and unemployment: evidence from a sample of 80 countries and nonlinear estimates

This article contributes to the discussion on the dynamic nexus of renewable energy consumption and unemployment by incorporating nonlinear cointegration and causality analysis. Using a sample of 80 countries spanning the period 1990–2013 and the advanced generation of unit root, cointegration and nonlinear Granger causality methodological approaches in panel data, we obtain mixed results about the impact of renewable energy consumption on unemployment. Although the total findings document a positive impact of renewable energy consumption on unemployment, disaggregated data across specific regions, such as Asia and Latin America, highlight the favourable effect on unemployment, implying that the effect of renewable energy consumption on jobs creation depends on the cost of adopting renewable energy technologies and energy efficiencies that seem to vary across the regions under investigation.     

‘The Navigator Network’: a New Zealand futurewatch case study

New Zealand's ‘Navigator Network’ is a national scanning network of scientists and policy analysts providing ‘early alert’ advice about emerging areas of science and technology. It was established by the Ministry of Research, Science and Technology (MoRST) to enhance the government's readiness to respond to the opportunities and risks around new technologies, particularly in biotechnology and nanotechnology. The Navigator Network has been tailored to the New Zealand context, which is characterised by a small, well-connected government sector and a strong focus on agricultural biotechnology and food. The network builds on these features, and is ‘people-centric’ rather than ‘information-centric’, using dialogic approaches to generate new knowledge between diverse stakeholder groups. It also focuses on building futures capability in the government and science sectors. Representatives from government agencies are integrated into the process as scanners to facilitate uptake. It also has an adaptive development process via an action learning component.     

Estimating and testing the compensated double-log demand model

In spite of the proliferation of flexible functional forms for consumer demand systems, the double-log demand model continues to be popular, especially in applied work calling for single-equation models. It is usually estimated in uncompensated form. It can also be estimated in compensated form, by deflating the income variable alone using Stone's price index. The compensated form has the same right-hand side as a single-equation version of the popular linear approximation to the Almost Ideal demand model, facilitating the construction of a test for choosing between the two alternatives. This paper demonstrates these results, develops the specification test, and illustrates its application using US meat consumption data. Simulations suggest that the test is well-behaved with good power in typical applications.     

Geographic scope of proximity effects among small life sciences firms

A large number of studies have demonstrated that proximity effects from knowledge spillovers, network externalities and other forms of knowledge transfers among like firms are geographically bounded. However, only a few studies have measured the strength and geographic scope of such externalities and even fewer have done so for firms in very close proximity. In this study, we examine the size and geographic scope of proximity effects among all life science firms that have received Small Business Innovation Research (SBIR) grants in the US over a 23-year period while controlling for relevant regional and firm characteristics. From our empirical analysis, we conclude that proximity effects among nearby small life science firms are strong within one-tenth of a mile distance and are exhausted within a radius of 1.5 miles. By examining the location of all firms in the sample, we offer possible explanations for the narrow geographic scope of the measured proximity effects. We also explain the significance of such findings for academic research that seeks to understand the nature of spatial externalities and for public policy.     

Exploring Comparative Ratings and Constituent Facets of Public Trust in Risk Regulatory Bodies and Related Stakeholder Groups

This paper reports on two comparative ranking tasks performed by a sample of the British citizens (N = 304). The first was designed to compare levels of relative trust vested in a sample of UK risk regulatory bodies and associated stakeholder groups. The second sought to elicit a ranking of a range of previously identified facets of social trust referenced to their desirability as attributes of a government funded risk regulatory body. The ranking tasks were embedded within a broader programme of research focused on “Evaluating public understandings of and trust in the Health and Safety Executive” (Pidgeon et al., 2003). It is argued that deriving rankings of multi‐faceted phenomena using the method of paired comparisons offers a more robust approach to rating social trust entities than the direct ranking techniques used in previous studies in this area. Results are discussed with reference to qualitative findings from the broader programme of work on public trust in HSE (Pidgeon et al., 2003) and the wider literature on public trust in risk regulation.     

Baltic Dry Index and the democratic window of opportunity

In their seminal paper, Brückner and Ciccone (2011) document that a significant effect of democratic change may be triggered by negative transitory economic shocks, and that rainfall can open a democratic window of opportunity in sub-Saharan Africa (SSA). As a complement, this paper uses within-country variation in the Baltic Dry Index (BDI) as a source of transitory negative income shocks to SSA countries. The BDI reflects the cost of utilizing dry bulk carriers, which are specially designed vessels for transporting primary goods internationally, where these goods dominate the output and export sectors of the SSA economies. We find that positive BDI cost shocks are followed by significant contraction in income through trade channel and significant improvement in democratic institutions, where BDI can open a window of opportunity for democratic improvement. Instrumental variables estimates indicate that following a negative income shock of one percentage point, democracy scores improve by around 4–5 percentage points on average.     

Cherries for sale: The incidence and timing of cross-border M&A

This paper develops a model of cross-border M&A activity that features firm-level productivity shocks and endogenous export activity. We show that foreign firms will be relatively more attracted to targets in the domestic country that had high productivity levels that induced them to invest in large export networks several years prior to acquisition, but subsequently experienced a negative productivity shock (i.e., cherries for sale). From the theory we derive a dynamic panel binary choice empirical model to predict cross-border M&A activity, and find strong evidence for our hypotheses connecting the evolution of firm-level productivity to the ultimate targets of cross-border acquisitions using French firm-level data.     

EXPLORING THE IMPACT OF FOREIGN AID ON CORRUPTION: HAS THE “ANTI‐CORRUPTION MOVEMENT” BEEN EFFECTIVE?

Though many studies have referred to an “anti‐corruption movement” beginning in the 1990s by major international organizations, none has empirically tested its effectiveness on corruption. The data show that from 1997 onward, the impact of multilateral aid is strongly and robustly associated with lower corruption levels, while bilateral aid is shown to be an insignificant determinant. An increase in any official development assistance (ODA) pre‐1997 is associated with higher levels of corruption or has no impact at all. Using panel data from 1986 to 2006, this study reveals a more nuanced relationship between ODA and corruption than previous studies and demonstrates that when disaggregating the time periods, there are sensitive temporal effects of ODA's effect on corruption overlooked by earlier studies, and provides initial evidence of the effectiveness of the international organization anti‐corruption movement in the developing world.     

The Economics of Pensions

This paper sets out the economic analytics of pensions. Afterintroductory discussion, successive sections consider the effectsof different pension arrangements on labour markets, on nationalsavings and growth, and on the distribution of burdens and benefits.These areas are controversial and politically highly salient.While we are open about expressing our own views, the main purposeof the paper is to set out the analytical process by which wereach them, to enable readers to form their own conclusions.

Regulation and Productivity Performance

The paper reviews theory and evidence on the ways in which regulationaffects productivity outcomes. In a context of endogenous growth,it is argued that traditional measures of compliance costs missthe potentially most important impacts of regulation on productivitywhich occur through changes in incentives to invest and to innovate.Recent attempts to measure cross-country variations in the strengthof product-market and employment regulation are considered andsome weaknesses are highlighted. Nevertheless, consistent withendogenous growth models, there appears to be quite strong evidencethat regulations which inhibit entry into product markets havean adverse effect on TFP growth in OECD countries. Althoughthere are some discrepancies in the evidence, on most measuresthe UK appears lightly regulated relative to France and Germany,and this may have contributed to a reduction in the recent pastin the UK's TFP gap.
