Stable Asymptotics for M‐estimators

We review some first‐order and higher‐order asymptotic techniques for M‐estimators, and we study their stability in the presence of data contaminations. We show that the estimating function (ψ) and its derivative with respect to the parameter play a central role. We discuss in detail the first‐order Gaussian density approximation, saddlepoint density approximation, saddlepoint test, tail area approximation via the Lugannani–Rice formula and empirical saddlepoint density approximation (a technique related to the empirical likelihood method). For all these asymptotics, we show that a bounded ψ (in the Euclidean norm) and a bounded (e.g. in the Frobenius norm) yield stable inference in the presence of data contamination. We motivate and illustrate our findings by theoretical and numerical examples about the benchmark case of one‐dimensional location model.     

Fiscal policy under loose commitment

Due to time-inconsistency or political turnover, policymakers' promises are not always fulfilled. We analyze an optimal fiscal policy problem where the plans made by the benevolent government are periodically revised. In this loose commitment setting, the properties of labor and capital income taxes are significantly different than under the full-commitment and no-commitment assumptions. Because of the occasional reoptimizations, the average capital income tax is positive even in the long-run. Also, the autocorrelation of taxes is lower, their volatility with respect to output increases and the correlation between capital income taxes and output changes sign. Our method can be used to analyze the plausibility and the importance of commitment in a wide-class of dynamic problems.     

Productivity,innovation strategies and industrial relations in SMEs. Empirical evidence for a local production system in northern Italy

The paper aims to provide an original contribution to evaluating several kinds of relations between four areas of innovation activities – training, technology, organization, ICT (information and communication technologies) – and industrial relations and firm’s economic performance. Quantitative evidence for a SME‐based local production system is provided by exploiting two datasets: the first is derived from a direct survey carried out in 2005 collecting data on innovations, labour flexibility and industrial relations; the second is represented by a panel of official balance sheets data for the period 1998–2004. The analysis is divided in two consequential parts. We first examine the drivers of different innovation strategies and subsequently we exploit innovation indicators as potential drivers of firm’s productivity. The results show that training activities and organizational changes have strong links with many industrial relations indicators, thus emerging as industrial relations driven innovations. On the contrary, ICT and technological innovation seem to be more influenced by firms’ past performances than by industrial relations. The analysis on labour productivity drivers shows that training activities are the most relevant factors; then, ranked consequently, technological innovation, organisational innovations and, finally, ICT also appear to impact on productivity levels. It is worth noting that the role of ICT emerges more robustly when endogeneity is specifically addressed. Finally, the role of firm size seems here to be overshadowed by other drivers.     

The two sides of academic research: do basic and applied activities complement each other?

It is generally acknowledged that the cuts in government funding for research implemented in several European countries will induce academic researchers to increase their interaction with non academic entities to promote the acquisition of external funding for research. Indirectly this implies that there will be a shift in the focus of academic scientific activity from basic to applied research via private research contracts and consultancy work. The aim of our paper is to assess the extent of the trade-off between basic research and applied activity in academic research departments. We use data for the universe of Italian academic departments over the period 2006–2011 and estimate whether increased applied activity is substituting or complementing basic research activity. We provide empirical evidence of a strong substitution effect for life sciences departments and, to a lesser extent, for engineering and technology departments, while there does not seem to be evidence of a substitution effect for departments whose scientific activity revolves around basic science.     

Reshaping the schooling system: The role of immigration

This paper studies how the schooling system may be impacted by the number and skill type of immigrants. When the number of low-skilled immigrants is large, the education regime tends to become segregated. Wealthy locals are more likely to choose private schools and vote for a lower tax rate to finance public education. In contrast, high-skilled immigrants tend to reinforce the public system. The optimal immigration policy is highly skill-biased. The admission of high-skilled immigrants expedites redistribution toward the less-skilled local households through both a stronger fiscal support for public education and a reduction in the skill wage premium.     

Exploring the role of human resources in technology out-licensing:an empirical analysis of biotech newtechnology-based firms

Out-licensing is a technology exploitation option to generate revenues without investing in downstream complementary assets. Despite its increasing strategic relevance, the strong complexity of out-licensing activity determines a substantial discrepancy in firms’ ability to extract monetary benefits from this practice. Searching for determinants of out-licensing performance, the paper focuses in particular on the role of licensing managers. Based on a multiple case study analysis involving 26 out-licensing deals executed in seven Italian biotech NTBFs, the study shows that expert scientific skills, extensive licensing practice and prior employment in multinationals, but not an intense social network, characterise successful licensing managers, while high delegation and powerful intrinsic rewards enable individual capacities of licensing managers to translate into actual economic value.     

Stiglitz on Globalization and Development with an Eye to Keynes

Abstract

Joseph Stiglitz has laid out many of the issues central to the debate on globalization in a compelling story in a recent influential book. Globalization has become a contentious issue because the economic policies advocated for and, at times, almost imposed upon developing countries by international organizations such as the International Monetary Fund, the World Bank and the World Trade Organization are based on misconceptions about how market systems work. Market fundamentalism underlies the entire policy framework of the Washington Consensus. The limits of this approach are nowhere clearer than in the examples presented by developing and transition economies. Many policy missteps could have been avoided by adopting the main insights of traditional Keynesian theory, the basic lessons of which remain valid, even if it has been largely excised from the IMF's recipe book. The results of 20 years of market fundamentalism make it clear that globalization and development are distinct issues and that the former does not necessarily entail the latter. In order to understand how they are connected we need to supplement macroeconomic analysis with studies of how international economic integration comes about.     

THE (IR)RELEVANCE OF THE NRU FOR POLICY MAKING: THE CASE OF DENMARK

We reconsider the central role of the natural rate of unemployment (NRU) in forming policy decisions. We show that the unemployment rate does not gravitate towards the NRU due to frictional growth, a phenomenon that encapsulates the interplay between lagged adjustment processes and growth in dynamic labour market systems. We choose Denmark as the focal point of our empirical analysis and find that the NRU explains only 33% of the unemployment variation, while frictional growth accounts for the remaining 67%. Therefore, our theoretical and empirical findings raise doubts as to whether the NRU should play such a key instrumental role in policy making.     

The effects of universities' proximity to industrial districts on university–industry collaboration

There is increasing awareness that university–industry collaboration provides an important knowledge transfer channel and, thus, is a powerful driver of innovation. Universities are increasingly being asked to play incisive roles in the process of regional economic development. This paper assesses the extent to which university–industry collaboration, expressed in terms of private funding for university consulting research activities, is affected by the geographic proximity of an academic institution to an Industrial District (ID). Although the economic literature insists on the positive effects of proximity for these collaborations, empirical work on Italian ID so far shows no particular effects. This paper provides new insights into the effects of academic proximity to ID on university–industry collaboration, by presenting robust evidence that proximity to districts promotes the establishment of collaboration agreements. This sheds new light on the need for targeted policies to support local productive systems. The empirical evidence is based on an analysis of qualitative information and an econometric analysis of financial data for the whole population of Italian university departments engaged in research in the Engineering and Physical Sciences.
