Tareas,ocupaciones y salarios en países de la OCDE

En este artículo se investigan los vínculos entre ingresos, capital humano y tareas laborales, utilizando información internacionalmente comparable del PIAAC (OCDE) sobre competencias de adultos. Tomando el marco teórico de Autor y Handel (2013), se amplía el análisis empírico a 21 países de la OCDE. Los datos permiten tener en cuenta tanto el nivel de instrucción como una medida de las competencias cognitivas. Los resultados confirman que las tareas que implica cada ocupación tienen influencia en las diferencias salariales tanto entre ocupaciones como dentro de cada una y proporcionan pruebas empíricas del poder de predicción del modelo para un gran número de países.

The Evolution of the Credit‐to‐GDP Ratio: An Empirical Analysis

We assess the persistence of the credit‐to‐GDP ratio over more than 130 years of data for 11 advanced economies, employing an approach based on fractional integration and allowing for nonlinearities. We show how the time series properties of the data changed around World War II (WWII). Moreover, our findings are consistent with the idea that the supply of mortgage loans has been particularly strong since WWII, in the sense that the degree of integration of the leverage ratio obtained with only these loans is larger than that of the ratio obtained with the total loans for almost all the studied countries. Nevertheless, it is generally the case that both types of ratios show a higher degree of integration after WWII than before it, though often insignificantly, and that their time trends are significant only after WWII.     

Recent Developments at DG Competition: 2017/2018

The Directorate General for Competition at the European Commission enforces competition law in the areas of antitrust, merger control, and state aids. This year’s article provides first a general presentation of the role of the Chief Competition Economist’s team and surveys some of the main achievements of the Directorate General for Competition over 2017/2018. The article then reviews: the Google Search (Shopping) case, the role of price discrimination in state aid cases; and the use of counterfactuals in merger cases where alternative transactions might have occurred absent the merger.     

Fiscal Policies and Credit Regimes: A TVAR Approach

This work investigates how the state of credit markets affects the impact of fiscal policies. We estimate a threshold vector autoregression (TVAR) model on US quarterly data for the period 1984–2010. We employ the spread between BAA‐rated corporate bond yield and 10‐year treasury constant maturity rate as a proxy for credit conditions. We find that the response of output to fiscal policy shocks is stronger and more persistent when the economy is in the ‘tight’ credit regime. Fiscal multipliers are significantly different in the two regimes: they are abundantly and persistently higher than one when firms face increasing financing costs, whereas they are feebler and often lower than one in the ‘normal’ credit regime. The results appear to be robust to different model specifications, fiscal foresight, alternative threshold variables, different measure of variables and sample periods.

How competition affects schools' performances: Does specification matter?

If the number of individuals is odd, majority rule is the only non-dictatorial strategy-proof social choice rule on the domain of linear orders that admit a Condorcet winner (Campbell and Kelly, 2003). This paper shows that the claim is false when the number of individuals is even, and provides a counterpart to the theorem for the even case.     

Competition Among Italian Junior‐Secondary Schools: A Variance‐Decomposition Empirical Analysis

The public economic theory emphasizes the potential role of competition in fostering the performance of educational systems. The rationale for pro‐competitive policies in education (i.e. vouchers, charter schools, tax deductions) is that schools can improve their quality responding to ‘pressures’ from nearby competitors. The objective of this paper is to analyze the potential relationship between (i) competition among schools and (ii) students’ achievement in Italy. While previous studies used OECD‐Pisa data for this purpose, here a new dataset about Italian schools has been employed: about 19,000 students in 150 schools constitute the sample. The reference framework is the idea that the presence of more schools in a certain area, and/or the proportion of students enrolled in private schools, should raise the performance of schools operating in that area through a ‘competition effect’. A multilevel strategy, which allows separating between‐areas variance in achievement scores, is employed. The findings support the view that competition has an impact, albeit little, on students’ achievement, and such competitive pressure is due to the number of schools, no matter if public or private.     

Non-existence of competitive equilibria with dynamically inconsistent preferences

This paper shows the robust non-existence of competitive equilibria even in a simple three period representative agent economy with dynamically inconsistent preferences. We distinguish between a sophisticated and naive representative agent. Even when underlying preferences are monotone and convex, at given prices, we show by example that the induced preference of the sophisticated representative agent over choices in first-period markets is both non-convex and satiated. Even allowing for negative prices, the market-clearing allocation is not contained in the convex hull of demand. Finally, with a naive representative agent, we show that perfect foresight is incompatible with market clearing and individual optimization at given prices.
