From the ‘econometrics of capital punishment’ to the ‘capital punishment’ of econometrics: on the use and abuse of sensitivity analysis

The academic debate over the deterrent effect of capital punishment has intensified again with a major policy outcome at stake. About two dozen empirical studies have recently emerged that explore the issue. Donohue and Wolfers (2005 Donohue, J and Wolfers, J. 2005. Uses and abuses of empirical evidence in the death penalty debate. Stanford Law Review, 58: 791–845. [Web of Science ®] , [Google Scholar]) claim to have examined the recent studies and shown the evidence not to be robust to specification changes. We argue that the narrow scope of their study does not warrant this claim. Moreover, focusing on our two studies that they have examined, we show the deterrence findings to be robust, while their work has serious flaws and their reporting appears to be selective. The selectivity is biased towards showing ‘no deterrence’.     

A wavelet analysis of capital markets’ integration in Latin America

The continuous wavelet transform analysis may provide a rich and flexible framework for the analysis of time series which exhibit less stable statistical properties, such as the ones describing the dynamic trajectory of capital markets. In contrast to the Fourier analysis, wavelet transform preserves information on both time and frequency. We provide a summary of the most important features of this framework. By involving the concept of coherence as well as its partial and multiple forms, we analyse the connections between Santiago Stock Exchange, Mexican Stock Exchange and BM&FBOVESPA São Paulo Stock Exchange, for a time span which covers the 23 September 2003–12 March 2014 period. We highlight the existence of several significant forces of regional integration and of a short- to medium-run synchronization process between these markets. We conclude that deeper structural and institutional reforms are required in order to enhance the sustainable development and more profound integration of these markets.     

Measuring the degree of competition in Pakistan’s banking industry: an empirical analysis

Pakistan’s banking industry has gone through significant transformation from being in a heavily state regulated and controlled environment to a more liberalized market structure in recent years. This liberalization of banking industry in Pakistan has raised concerns over the dominant banks’ exercise of market power on account of increase in market concentration due to mergers and acquisitions, high profitability in banking sector and increasing interest rate spread. Present study therefore explicitly tests the market conduct of banks using quarterly panel data of 30 banks from 2004 to 2012 and employing Panzar–Rosse, Bresnahan–Lau, Hall–Roeger and Boone’s approaches to study market power. Our findings suggest that Pakistan’s banking industry is working in a competitive environment and we find little evidence for the exercise of market power by the dominant banks. Our results remain robust across all these approaches to measure market power. These findings indicate that the liberalization and deregulation of Pakistan’s banking industry has been successful in improving the competitive conditions in the market.     

Sraffa: the theoretical world of the ‘old classical economists’ *

Sraffa's mature work is seen here as a re-discovery and resumption of the ‘submerged and forgotten’ approach of the ‘old classical economists from Adam Smith to Ricardo’. Wages determined by broad economic and social forces entail there product prices determined independently of demand and supply functions. Some main questions raised for the modern economists by this radical reorientation of economic theory are then considered in order to conclude that it is aginst that background that Sraffa's mature work should be set with its three main contributions, of a rediscovery of the approach, of a complete and transparent solution of the problems of price determination it raises, and of its application to the critique of neoclassical theory. Among several developments originating from Sraffa's seminal work, two are singled out for mention: (i) the possibility of deficiencies of aggregate demand in the long period no less than in the short one; this follows naturally from the abandonment of the neoclassical theory of distribution, of which the role of the interset rate in equilibrating savings and investment is a corollary; (ii) the question of the distribution of the surplus between wages and profits in a modern economy where wages are no longer confined to subsistence.     

Walras’ theory of capital formation: an intertemporal equilibrium reformulation

We develop a mainstream reformulation of the original Walras?? model of capital accumulation. We overcome the shortcomings of the original model. First, we prove the existence of intertemporal competitive equilibria. Our proof combines a well known theorem due to Yannelis and Prabhakar (J Math Econ 12:233?C245, 1983) with a lemma due to Geanakoplos (Econ Theory 21:585?C603, 2003). Secondly, we remedy the indeterminacy of allocation of savings across multiple types of capital goods by introducing a storage technology. Finally, we show that, for stored capital goods, the equality of rates of returns emerges endogenously in equilibrium, while it was imposed by Walras from the outset in his original contribution.     

‘Social enterprise spin-outs’: an institutional analysis of their emergence and potential

The recent phenomenon of public sector ‘social enterprise spin-outs’ is examined in order to critically assess their nature and innovative potential as providers of public services. The study utilises a theoretical model of institutional creation and change which incorporates key characteristics of ‘corporate spin-outs’ and ‘university spin-outs’ to facilitate the examination of their public sector counterparts, drawing on interview evidence from 30 newly-established social enterprise providers of health and care services in England. A main contribution of the paper is to provide a conceptual framework which sheds light on the strengths and potential vulnerabilities of social enterprise spin-outs as novel organisations that span the public, private and civil society sectors.     

Quantifying the impacts of China’s currency depreciation and capital control: a CGE analysis

A dynamic global multi-regional computable general equilibrium (CGE) model is built to study the effects of Renminbi (RMB) depreciation and capital account liberalization. The simulation results suggest that although the depreciation of RMB can promote China’s trade surplus, it will nevertheless discourage domestic investment, consumption and lead to a decrease of real GDP.     

The ‘Rise of the South’: Global Convergence at Last?

This article offers a political economy review of the literatures and the empirical evidence concerning the ‘Rise of the South’. The study focuses on global convergence (in the long-term, in the last 30 years, and in the aftermath of the 2008 global crisis), economic decoupling between developing and advanced economies, and the economic strategies which may help catching-up, especially the ‘flying geese’ paradigm and industrial policies supporting manufacturing sector growth. It shows that the mainstream literature suffers from significant weaknesses; that empirical claims concerning convergence and decoupling have been exaggerated, and that flying geese-type strategies are severely limited. Examination of the drivers of growth in the South and the policies implemented in key converging countries support the claim that political economy approaches can offer valuable policy insights to countries grappling with the challenges of long-term growth and development.     

Professional ‘amateurs’ in the NCAA: the impact of downstream demand

We argue that student-athletes are amateur in title only; they are actually professional athletes in all accounts of their actions. This occurs because of the downstream demand of their athletic success: coaches are paid professionals. As a paid professional, these coaches are held accountable for the performances of their team, i.e. they are hired and fired based on this performance. Within the constraints of the National Collegiate Athletic Association guidelines, coaches make the rules for their athletes, which the athletes are required to follow. As such, the athletes themselves are professionals acting under professional incentives and are amateurs in title only.     

Robots and us: towards an economics of the ‘Good Life’

(Expected) adverse effects of the ‘ICT Revolution’ on work and opportunities for individuals to use and develop their capacities give a new impetus to the debate on the societal implications of technology and raise questions regarding the ‘responsibility’ of research and innovation (RRI) and the possibility of achieving ‘inclusive and sustainable society’. However, missing in this debate is an examination of a possible conflict between the quest for ‘inclusive and sustainable society’ and conventional economic principles guiding capital allocation (including the funding of research and innovation). We propose that such conflict can be resolved by re-examining the nature and purpose of capital, and by recognising mainstream economics’ utilitarian foundations as an unduly restrictive subset of a wider Aristotelian understanding of choice.     

Anti-poverty competences in a multilevel government: an empirical analysis of citizens’ preferences in Europe

This article aims to investigate individuals’ perceptions about institutions that should be primarily responsible for reducing or preventing poverty, which is a dramatic phenomenon that became a crucial issue in European countries over recent years. We propose an empirical analysis based on European survey data and investigate some citizens’-level and country-level variables that potentially affect individuals’ attitudes. Our results suggest that country-level economic and institutional characteristics do significantly affect individual preferences for the governance of anti-poverty policies.     

The determinants of cleaner energy innovations of the world’s largest firms: the impact of firm learning and knowledge capital*

In this paper, we address the determinants of clean energy inventions by 946 large firms. We use a new set of large firms’ patent portfolios and we broaden and deepen existing literature on this issue in two main ways: first, we conduct our study directly at the firm level and not at the industry or national levels and second, we do not focus on a single industry but encompass all industrial sectors. Drawing on firm (internal and external) knowledge and knowledge accumulation, we show there is a robust positive association between the (past) knowledge accumulated capital related to clean technologies and the number of inventions produced in that field, even after controlling for industry and nation fixed effects and other factors. The same relation works for (past) knowledge-accumulated capital in other (non-clean) technologies. However, the relation’s impact on the number of clean inventions produced is much lower. The magnitudes of our coefficient are in line with that obtained previously on firms in the auto-industry or at the sectoral level.     

Beach ‘lovers’ and ‘greens’: A worldwide empirical analysis of coastal tourism

This paper examines worldwide tourist coastal destination choice using a comprehensive global dataset at the country level, for both domestic and international tourists. This data includes a systematic profile of the countries' coastline with respect to economic and natural environments, such as marine biodiversity related indicators. Tourist demand is modelled using a system of simultaneous structural equations estimated by a 3SLS routine. We identify two tourist demand segments, denoting different preferences for the worldwide coastal destinations. International tourists choose their coastal destination because they have a strong preference for the cultural and natural environments. This, in turn, depends on the destination of country's coastal habitat abundance and marine biodiversity. We label this segment of coastal tourism, as “greens”. Alternatively, domestic tourists have a preference for beach characteristics, in particular beach length. This in turn depends on anthropogenic pressure, the built environment and climatic variables. For this reason we interpret this tourism segment as “beach lovers”. This information is, in turn, of high significance for stimulating coastal tourism demand as well as for identifying market based policy instruments with the objective to finance the conservation of environmental and cultural capital hosted at the coastal communities.     

Physicians’ use of medical technology: an analysis of the introduction and subsequent failure of drug-eluting stents

Using data on cardiac patients in Florida hospitals from 2003 to 2007, we analyse the adoption and deadoption of a major new medical technology, drug-eluting stents (DESs). The Food and Drug Administration approved DESs in April 2003 and physicians rapidly adopted the new technology. In March 2006, a presentation was made at the American Cardiology Conference which showed that patients receiving DES in real-world settings suffered higher rates of mortality and myocardial infarction than those receiving stents without drugs. We examine the utilization of DES from April 2003 to the end of 2007. Using a hospital fixed-effects model, we find that board-certified and top-trained physicians were initially quicker to adopt DES. Over time, this effect dissipated and top-trained physicians were less likely to use DES by the time new clinical trials indicated they could be problematic. After the news, board-certified and top-ranked physicians were less likely to change their behaviour. Physicians’ own experience also contributes to the use of technology and the effects are stronger for non-board-certified physicians. We conclude that even within hospitals, physician training and experience play an important role in explaining differences in rates of technology use.     

Stochastic accumulation of human capital and welfare in the Uzawa–Lucas model: an analytical characterization

Stochastic growth models are often solved numerically, because they are not tractable in general. However, recent several studies find the closed-form solution to the stochastic Uzawa–Lucas model in which technological progress or population dynamics follow a Brownian motion process with one or two parameter restriction(s). However, they assume that the return on the accumulation of human capital is deterministic, which is inconsistent with empirical evidence. Therefore, I develop the Uzawa–Lucas model in which the accumulation of human capital follows a mixture of a Brownian motion process and many Poisson jump processes, and obtain the closed-form solution. Moreover, I use it to examine the nexus between human capital uncertainty, technological progress, expected growth rate of human capital, and welfare.
