Building a System of Indicators to Evaluate the Right of a Child to Play

This study presents the results of a research project whose objective is to propose measures to evaluate the right of children to engage in play, as recognised in the Convention on the Rights of the Child. After exhausting documentation and statistical sources, a lack of measures related to this right was clear. This led to the formation of discussion groups about play with schools, families and social agents. From this, an initial matrix was developed and submitted to experts who selected the most suitable measures. This resulted in the SIDERJU matrix, composed of measures for the structure, process and result.     

COMPARATIVE ADVANTAGE AND THE CROSS‐SECTION OF BUSINESS CYCLES

Business cycles are both less volatile and more synchronized with the world cycle in rich countries than in poor ones. We develop two alternative explanations based on the idea that comparative advantage causes rich countries to specialize in industries that use new technologies operated by skilled workers whereas poor countries specialize in industries that use traditional technologies operated by unskilled workers. (1) Because new technologies are difficult to imitate, the industries of rich countries enjoy more market power and face more inelastic product demand than those of poor countries. (2) Because skilled workers are less likely to exit employment as a result of changes in economic conditions, industries in rich countries face more inelastic labor supplies than those of poor countries. We show that either asymmetry in industry characteristics can generate cross‐country differences in business cycles that resemble those we observe in the data. (JEL: E32, FA5, F41)     

COUNTRY PORTFOLIOS

Capital flows to developing countries are small and mostly take the form of loans rather than direct foreign investment. We build a simple model of North–South capital flows that highlights the interplay between diminishing returns, production risk, and sovereign risk. This model generates a set of country portfolios and a world distribution of capital stocks that resemble those in the data. (JEL: F32, F34)     

Strategies and Tools for Entrepreneurial Resource Access: A Cross‐disciplinary Review and Typology

Given that gaining access to external resources is a critical component of entrepreneurial activity, a great deal of research has been done in an attempt to predict and explain this phenomenon. Unfortunately, this literature is largely scattered across a wide variety of somewhat disconnected research streams, which makes interpreting the insights that have been hitherto gained challenging. In response, the authors identify a sample of 76 relevant articles from the leading management and entrepreneurship journals that examine entrepreneurial access to resources. Using a narrative synthesis approach, they then organize these articles based on the strategies (projective and/or interpersonal) and tools (words, actions, associations and/or intangibles) by which entrepreneurs gain access to resources. Based on this categorization, the authors discuss the major themes in the extant literature and offer suggestions for how to move research on entrepreneurial access forward in the future.     

Beyond Value‐at‐Risk: GlueVaR Distortion Risk Measures

We propose a new family of risk measures, called GlueVaR, within the class of distortion risk measures. Analytical closed‐form expressions are shown for the most frequently used distribution functions in financial and insurance applications. The relationship between GlueVaR, value‐at‐risk, and tail value‐at‐risk is explained. Tail subadditivity is investigated and it is shown that some GlueVaR risk measures satisfy this property. An interpretation in terms of risk attitudes is provided and a discussion is given on the applicability in nonfinancial problems such as health, safety, environmental, or catastrophic risk management.     

Duocentered networks

When a pair of individuals is central to a research problem (e.g., husband and wife, PhD student and supervisor) the concept of “duocentered” networks can be defined as a useful extension of egocentered networks. This new structure consists of a pair of central egos and their direct links with alters, instead of just one central ego as in the egocentered networks or multiple egos as in complete networks. The key point in this kind of network is that ties exist between the central pair of egos and between them and all alters, but the ties among alters are not considered. Duocentered networks can also be considered as a compromise between egocentered and complete networks. Complete network measurements are often costly to obtain and tend to contain a large proportion of missing data (especially for peripheral actors). Egocentered network data are less costly but a lot of information is lost with their use when a pair of individuals is the relevant unit of analysis.     

MANAGING CREDIT BUBBLES

We study a dynamic economy where credit is limited by insufficient collateral and, as a result, investment and output are too low. In this environment, changes in investor sentiment or market expectations can give rise to credit bubbles, that is, expansions in credit that are backed not by expectations of future profits (i.e., fundamental collateral), but instead by expectations of future credit (i.e., bubbly collateral). Credit bubbles raise the availability of credit for entrepreneurs: this is the crowding‐in effect. However, entrepreneurs must also use some of this credit to cancel past credit: this is the crowding‐out effect. There is an “optimal” bubble size that trades off these two effects and maximizes long‐run output and consumption. The equilibrium bubble size depends on investor sentiment, however, and it typically does not coincide with the “optimal” bubble size. This provides a new rationale for macroprudential policy. A credit management agency (CMA) can replicate the “optimal” bubble by taxing credit when the equilibrium bubble is too high and subsidizing credit when the equilibrium bubble is too low. This leaning‐against‐the‐wind policy maximizes output and consumption. Moreover, the same conditions that make this policy desirable guarantee that a CMA has the resources to implement it.     

Environmental taxation and the double dividend hypothesis in CGE modelling literature: A critical review

Computable general equilibrium (CGE) modelling is a flexible and open way to model the economic systems that allow practitioners to assess the impacts of different policies or external shocks over an economic system. There is some empirical literature dedicated to test the double dividend hypothesis of an environmental tax reform using CGE models. This hypothesis claims that is possible to obtain an improvement of both environmental and economic conditions by imposing an environmental tax and recycling revenues obtained to reduce other pre-existing taxes. This research provides a comprehensive review of this literature including a statistical and a meta-regression analysis. 69 different simulations from 40 studies have been analyzed. 55% of simulations have achieved a double dividend, concluding that although the environmental dividend is almost always achieved, the economic dividend still remains an ambiguous question that needs further research.
