Fiscal Policy and Economic Stability: Does PIGS stand for Procyclicality In Government Spending?

The Financial Crisis has hit particularly hard countries like Ireland or Spain. Procyclical fiscal policy has contributed to a boom-bust cycle that undermined fiscal positions and deepened current account deficits during the boom. We set up an RBC model of a small open economy, following Mendoza (1991), and introduce the effect of fiscal policy decisions that change over the cycle. We calibrate the model on data for Ireland, and simulate the effect of different spending policies in response to supply shocks. Procyclical fiscal policy distorts intertemporal allocation decisions. Temporary spending boosts in booms spur investment, and hence the need for external finance, and so generates very volatile cycles in investment and the current account. This economic instability is also harmful for the steady state level of output. Our model is able to replicate the relation between the degree of cyclicality of fiscal policy, and the volatility of consumption, investment and the current account observed in OECD countries.

The Impact of Regulation on Pricing Behavior in the Spanish Electricity Market

In this paper we measure the impact of regulatory measures which affected the Spanish electricity wholesale market in the period 2002-2005. Our approach is based on the fact that regulation changes firms' incentives and therefore their market behavior. In the absence of any regulation firms would choose profit- maximizing prices on their residual demands so that the observed gap between optimal and actual prices provides a measure of the effect of regulation. Our results indicate that regulation has decreased wholesale prices considerably, but became less effective at the end of the sample period which explains the change of regulatory regime introduced in 2006.

Strategic Interaction and Conventions

The scope of the paper is the literature that employs coordination games to study social norms and conventions from the viewpoint of game theory and cognitive psychology. We claim that those two alternative approaches are complementary, as they provide different insights to explain how people converge to a unique system of self-fulfilling expectations in presence of multiple, equally viable, conventions. While game theory explains the emergence of conventions relying on efficiency and risk considerations, the psychological view is more concerned with frame and labeling effects. The interaction between these alternative (and, sometimes, competing) effects leads to the result that coordination failures may well occur and, even when coordination takes place, there is no guarantee that the convention eventually established will be the most efficient.

New Keynesian Model Features that Can Reproduce Lead, Lag and Persistence Patterns

This paper uses a new method for describing dynamic comovement and persistence in economic time series which builds on the contemporaneous forecast error method developed in den Haan (2000). This data description method is then used to address issues in New Keynesian model performance in two ways. First, well known data patterns, such as output and inflation leads and lags and inflation persistence, are decomposed into forecast horizon components to give a more complete description of the data patterns. These results show that the well known lead and lag patterns between output and inflation arise mostly in the medium term forecasts horizons. Second, the data summary method is used to investigate a rich New Keynesian model with many modeling features to see which of these features can reproduce lead, lag and persistence patterns seen in the data. Many studies have suggested that a backward looking component in the Phillips curve is needed to match the data, but our simulations show this is not necessary. We show that a simple general equilibrium model with persistent IS curve shocks and persistent supply shocks can reproduce the lead, lag and persistence patterns seen in the data.

Travellers' Types

This paper uses subjects’ self-reported justifications to explain discrepancies between observed heterogeneous behavior and the unique equilibrium prediction in a one-shot traveler’s dilemma experiment (TD). Principal components (PC) analysis suggests that iterative reasoning, aspiration levels, competitive behavior, attitudes towards risk and penalties and focal points may be behind different choices. Such reasons are coherent with same subjects’ behavior in other tests and experiments in which these particular issues are prominent. Overall, we identify types of subjects whose motivations are consistent across tasks.

Unraveling Public Good Games: The Role of Priors

This paper provides experimental evidence on how players predict end game effects in a linear public good game. Our regression analysis yields a measure of the relative importance of priors and signals on subjects\' beliefs on contributions and allow us to conclude that, firstly, the weight of the signal is relatively unimportant, while priors have a large weight and, secondly, priors are the same for all periods. Hence, subjects do not expect end game effects and there is very little updating of beliefs.

La implicación del estudiante con la escuela

[Es]El objetivo de esta investigación ha sido analizar la implicación o compromiso de nuestros estudiantes con sus centros escolares. La implicación posee un componente conductual (la participación) y un componente psicológico (la identificación con el centro escolar). La muestra está compuesta por 656 alumnos de 14 colegios del País Vasco y Cataluña, divididos según diferentes tipologías de centro: 179 en pública-primaria, 151 alumnos en concertada-primaria, 203 alumnos en pública¬-secundaria y 123 alumnos en concertada-secundaria. Los resultados indican que las percepciones en las escalas de participación e identificación son más altas en los centros concertados, de primaria y con una sola línea educativa y modelo lingüístico. Así mismo hemos comprobado que existen correlaciones entre las dos dimensiones de la implicación y las variables independientes analizadas: autoconcepto y motivación académica, tipología de centro, trabajo de los profesores y el entorno familiar.

La evolución de la intensidad energética de la industria vasca entre 1982-2001: Un análisis de descomposición

In this article an index decomposition methodology is used to estimate the effect of intersectorial and intrasectorial changes in explaining the 38% reduction in industrial energy intensity in the Basque Autonomous Community from 1982 to 2001. Period-wise additive decomposition results show that (1) the decline is fully explained by intrasectorial changes and that (2) intersectorial changes have not contributed to reduce but to increase the energy intensity of the Basque industrial sector. However, timeseries decomposition analysis shows that (1) four different phases can be distinguished in the evolution of energy intensity of the Basque industry from 1982 to 2001 and (2) that the evolution of the “Iron and Steel” sector is determinant when explaining those phases. Moreover, the analysis stresses the necessity to disaggregate the “Iron and Steel” sector in order to be able to distinguish purely technological effects from the rest of intrasectorial changes.

Factors Facilitating Successful Educational Innovation with ICT in Schools

[EN]This paper proposes an approach to the concept of ICT-based innovation in schools, from the perspective of the factors that facilitate the innovative use of ICT. To this end, a scale has been developed and validated to identify these factors through the participation of 195 teachers from 16 schools considered by the Basque educational authorities as innovators in ICT. The results obtained attest to the validity and reliability of both the scale and the 5 key factors that influence innovation in technology-based teaching. This factor-based structure enables a holistic view of ICT innovation in schools across 3 key areas: school context, teachers and the education authorities.

On the Informational Role of Term Structure in the U.S. Monetary Policy Rule

This paper uses a structural approach based on the indirect inference principle to estimate a standard version of the new Keynesian monetary (NKM) model augmented with term structure using both revised and real-time data. The estimation results show that the term spread and policy inertia are both important determinants of the U.S. estimated monetary policy rule whereas the persistence of shocks plays a small but significant role when revised and real-time data of output and inflation are both considered. More importantly, the relative importance of term spread and persistent shocks in the policy rule and the shock transmission mechanism drastically change when it is taken into account that real-time data are not well behaved.

Endogenous Unions Formation

This paper analyzes the process of endogenous union formation in the context of a sequential bargaining model between a firm and several unions and tries to explain why workers may be represented by several unions of different sizes. We show that the equilibrium number of unions and their relative size depend on workers' attitudes toward the risk of unemployment and union configuration is independent of labor productivity.

Employment comovements at the sectoral level over the business cycle

This paper extends the technique suggested by den Haan (2000) to investigate contemporaneous as well as lead and lag correlations among economic data for a range of forecast horizons. The technique provides a richer picture of the economic dynamics generating the data and allows one to investigate which variables lead or lag others and whether the lead or lag pattern is short term or long term in nature. The technique is applied to monthly sectoral level employment data for the U.S. and shows that among the ten industrial sectors followed by the U.S. Bureau of Labor Statistics, six tend to lead the other four. These six have high correlations indicating that the structural shocks generating the data movements are mostly in common. Among the four lagging industries, some lag by longer intervals than others and some have low correlations with the leading industries indicating that these industries are partially influenced by structural shocks beyond those generating the six leading industries.
