Systemic risk measurement: Multivariate GARCH estimation of CoVaR

We modify Adrian and Brunnermeier’s (2011) CoVaR, the VaR of the financial system conditional on an institution being in financial distress. We change the definition of financial distress from an institution being exactly at its VaR to being at most at its VaR. This change allows us to consider more severe distress events, to backtest CoVaR, and to improve its consistency (monotonicity) with respect to the dependence parameter. We define the systemic risk contribution of an institution as the change from its CoVaR in its benchmark state (defined as a one-standard deviation event) to its CoVaR under financial distress. We estimate the systemic risk contributions of four financial industry groups consisting of a large number of institutions for the sample period June 2000 to February 2008 and the 12 months prior to the beginning of the crisis. We also investigate the link between institutions’ contributions to systemic risk and their characteristics.     

Sub-sovereign bond buyback: a way forward for debt-laden regions in austerity

ABSTRACT

Previous academic literature has criticised bond buyback as a ‘”boondoggle” benefiting a country’s creditors’—meaning that buybacks are a wasteful use of public money. This paper challenges the narrow financial–economic perspective behind that statement by adopting a broader socio-political framework that includes the potential benefits of buyback for citizens, not just financial market costs. In particular, buyback does not necessarily require a budget surplus via higher local taxes and/or increased austerity measures.     

Scope and scale economies in multi-utilities: evidence from gas,water and electricity combinations

Within the recent debate on liberalization of local public services, the paper investigates the cost properties of a sample of Italian public utilities providing in combination gas, water and electricity. The estimates from a Composite Cost Function econometric model (Pulley and Braunstein, 1992 Pulley, LB and Braunstein, YM. 1992. A composite cost function for multiproduct firms with an application to economies of scope in banking. Review of Economics and Statistics, 74: 221–30.  ) are compared with the ones coming from other traditional functional forms such as the Standard Translog, the Generalized Translog, and the Separable Quadratic. The results highlight the presence of global scope and scale economies only for multi-utilities with output levels lower than the ones characterizing the ‘median’ firm. This indicates that relatively small specialized firms would benefit from cost reductions by evolving into multi-utilities providing similar network services such as gas, water and electricity. However, for larger-scale utilities the hypothesis of null cost advantages is not rejected. Thus, it is possible that the recent diversification waves of leading companies are explained by factors other than cost synergies, so that the welfare gains that can be reasonably expected from such examples of horizontal integration, if any, are likely to be very low.     

Pricing to market, firm heterogeneity and the role of quality

We build a pricing-to-market (PTM) model with firm heterogeneity, which allows for imperfect competition and market segmentation in the presence of flexible exchange rates, horizontal and vertical differentiation and different tastes of consumers in destination markets. We derive firm’s pricing behaviour in response to price and quality competition shocks. We show that there is PTM heterogeneity across firms if quality has a role. We empirically assess the main predictions of our theoretical framework on Italian firm-level data. We document that export-domestic price margins are significantly affected by price and quality competitiveness factors even controlling for foreign demand conditions, size, export intensity, destination markets and unobservables. Finally, we provide evidence of strong heterogeneity across firms in their reaction to price and quality competitiveness.     

Age and firm growth: evidence from three European countries

This article provides new insights into the dependence of firm growth on age along the entire distribution of growth rates, and conditional on survival. Using data from the European firms in a global economy survey, and adopting a quantile regression approach, we uncover evidence for a sample of French, Italian and Spanish manufacturing firms with more than ten employees in the period from 2001 to 2008. We find that: (1) young firms grow faster than old firms, especially in the highest growth quantiles; (2) young firms face the same probability of declining as their older counterparts; (3) results are robust to the inclusion of other firms’ characteristics such as labor productivity, capital intensity and the financial structure; (4) high growth is associated with younger chief executive officers and other attributes that capture the attitude of the firm toward growth and change. The effect of age on firm growth is rather similar across countries.     

Fiscal Convergence, Business Cycle Volatility, and Growth

This paper analyzes the effects of fiscal convergence on business cycle volatility and growth. Using a panel of 11 EMU and 21 OECD countries and 40 years of data, we find that countries with similar government budget positions tend to have smoother business cycles. That is, fiscal convergence (in the form of persistently similar ratios of government surplus/deficit to GDP) is systematically associated with smoother business cycles. We also find evidence that reduced business cycle volatility through higher fiscal convergence stimulates growth. Our empirical results are economically and statistically significant, and robust.     

The strength of science and technology drivers for SME innovation

This analysis feeds into the academic debate on the most proficient innovation mode across firms, placing special emphasis on the characteristic case of small and medium enterprises (SMEs). Of the three main approaches considered, the first stresses the importance of innovation based on science and technology (STI) drivers, such as research and development (R&D) and human capital, whereas the second approach emphasises innovation based on learning by doing, by using and by interacting (DUI); the third, more recent approach is conceived as a combination of the former two (STI?+?DUI). In this paper, the three models are tested on a sample of 409 SMEs that have been supported by a public programme for innovation promotion developed by the Basque Government in Spain. The result is quite different from what is expected, yet it is insightful and potentially useful for both academics and policy-makers. Contrarily to what one would expect, SME innovation output is in fact more sensitive to STI drivers than to DUI drivers.     

The Stagnation Tendencies of Neoliberalism: A Review Essay

In his 2012 book, From Financial Crisis to Stagnation, Thomas Palley argued that the financial crisis of 2008 would be likely to result in a period of long-term stagnation. Both the crisis and the predicted stagnation, Palley argued, were the outcomes of policies pursued since the 1980s; the persistence of those policies explains the stagnation. Underpinning the policies and their consequences are the flaws of the neoliberal macro model and the particular role played by finance in that model. The rejection of Keynesianism meant the abandonment of the commitment to full employment. The neoliberal paradigm rests upon a foundation of ‘bad ideas’ that are located in political philosophy as much as in economic theory. Palley’s argument has a bearing on recent discussions among mainstream macroeconomists, whose interest in secular stagnation has been revived by the ‘ongoing crisis’. These discussions have left mostly unanswered the question of the causes of stagnation. The present essay argues that Palley’s concept of ‘structural Keynesianism’ can benefit from a closer association with the analysis of structural transformation and its effects on policy regimes and stagnation tendencies.     

You get what you give: theory and evidence of reciprocity in the sharing economy

We develop an analytical framework of peer interaction in the sharing economy that incorporates reciprocity, the tendency to increase (decrease) effort in response to others’ increased (decreased) effort. In our model, buyers (sellers) can induce sellers (buyers) to exert more effort by behaving well themselves. We demonstrate that this joint increased effort can improve the utility of both parties and influence the market equilibrium. We also show that bilateral reputation systems, which allow both buyers and sellers to review each other, are more responsive to reciprocity than unilateral reputation systems. By rewarding reciprocal behavior, bilateral reputation systems generate trust among strangers and informally regulate their behavior. We test the predictions of our model using data from Airbnb, a popular peer-to-peer accommodation platform. We show that Airbnb hosts that are more reciprocal receive higher ratings and that higher rated hosts can increase their prices. Therefore, reciprocity affects equilibrium prices on Airbnb through its impact on ratings, as predicted by our analytical framework.     

Fairness and intentionality in children’s decision-making

Few studies have addressed the role of different aspects of the Theory of Mind (ToM) (intentionality and false belief understanding) in decision-making by adults playing strategic games where the importance of fairness is crucial. Even more interesting, this topic has been less investigated with children. The goal of this research was to explore the development of the decisional behavior along with the understanding of fairness, intentions and first- and second-order false belief understanding in children who are just acquiring those abilities. Multiple rounds of the ultimatum game with a human and a non-human partner (child/roulette wheel) were played by 177 children in the age range of 5–10 years, who also completed classic false belief tasks. Results confirm the key role of fairness sensibility across age groups and different degrees of the relevance of ToM according to the variability of children’s decisional behavior (stable vs. dynamic).
