New challenges for the welfare state: The emergence of youth unemployment regimes in Europe?

In this article we discuss the emergence of ‘youth unemployment regimes’ in Europe, that is, a set of coherent measures and policies aimed at providing state responses to the problem of unemployment and, more specifically, youth unemployment. We classify these measures and policies along two main dimensions: unemployment regulations and labour market regulations. Using original data, we show how seven European countries locate on these two dimensions as well as within the conceptual space resulting from the combination of the two dimensions. Our findings show cross‐national variations that do not fit the traditional typologies of comparative welfare studies. At the same time, however, the findings allow for reflecting upon possible patterns of convergence across European countries. In particular, we show some important similarities in terms of flexible labour market regulations. In this regard, the recent years have witnessed a trend towards a flexibilisation of the labour market, regardless of the prevailing welfare regime.     

Political,Biographical, and Cultural Consequences of Social Movements

This essay reviews recent and less recent literature on the consequences of social movements and protest activities. It focuses on three types of consequences: political, personal and biographical, and cultural. Political consequences and, in particular, policy outcomes receive most attention, as they are those which have been addresses most often by students of social movements. The review of existing work shows that the field is full of valuable works dealing with this crucial issue and is rapidly growing thanks in particular to a new wave of scholars interested in this topic. Further work should pay more attention to the unintended consequences of social movements, look also at other types of impacts, and carry more comparative analyses.     

ENDOGENOUS NETWORKS IN RANDOM POPULATION GAMES

Population learning in dynamic economies traditionally has been studied in contexts where payoff landscapes are smooth. Here, dynamic population games take place over “rugged” landscapes, where agents are uncertain about payoffs from bilateral interactions. Notably, individual payoffs from playing a binary action against everyone else are uniformly distributed over [0, 1]. This random population game leads the population to adapt over time, with agents updating both actions and partners. Agents evaluate payoffs associated to networks thanks to simple statistics of the distributions of payoffs associated to all combinations of actions performed by agents out of the interaction set. Simulations show that: (1) allowing for endogenous networks implies higher average payoff compared to static networks; (2) the statistics used to evaluate payoffs affect convergence to steady-state; and (3) for statistics MIN or MAX, the likelihood of efficient population learning strongly depends on whether agents are change-averse or not in discriminating between options delivering the same expected payoff.     

Ethno-cultural diversity and the limits of the inclusive nation

ABSTRACT

Migration is often said, in the public discourse, to pose a threat to the nation. Yet, Western societies are undergoing an irreversible demographic change spurred in great part by international migration. Thus, the question about how to reconcile nation and diversity remains of crucial importance for many countries. By focusing on the case of Italy, the article attends to this issue, by exploring the response of leftist political parties. We analyse parliamentary debates and laws related to immigration and integration issues (1986–2014), focusing specifically on the Turco-Napolitano Law (1998), possibly the most progressive legislative attempt at incorporating migrants into the Italian nation. Our analysis shows a clear incongruence between the pluralist rhetoric of the political left and its legislative acts on migrants’ national incorporation. This finding is used to reflect on the limits and possibilities of the very idea of inclusive nation in the age of migration.     

Living Arrangements and the Elderly: An Analysis of Old-Age Mortality by Household Structure in Casalguidi, 1819–1859

The elevated levels of protection, assistance, and care enjoyed by the elderly living in complex households has long been a key assumption of many family system theories. However, although this hypothesis has been demonstrated for contemporary contexts, quantitative evidence for past populations is particularly scarce, if not nonexistent. This article investigates the relationship between old-age mortality and living arrangements in a mid–nineteenth century Tuscan population, where the joint family system of sharecroppers coexisted alongside the nuclear system of day laborers. Our findings demonstrate that within complex households, the complexity of relationships, gender inequalities, and possible competition for care and resources among the most vulnerable household members—namely, the elderly and the young—weakens the assumption that the elderly benefitted from lower rates of old-age mortality.     

Vertrauensunterstützung für sozio-technische ubiquitäre Systeme

Trust has been shown as a crucial factor for the adoption of new technologies. Surprisingly, trust literature offers very little guidance for systematically integrating the vast amount of behavioral trust results into the development of computing systems. The aim of this article is to develop a method for deriving trust supporting components for ubiquitous computing systems. The method is used to derive four trust supporting components for a ubiquitous restaurant recommendation system. Afterwards, the system is evaluated using a laboratory experiment with 166 undergraduate students. The results show that the users’ trust as well as their intention to use the system could be significantly increased. To the best of our knowledge, this is the first article developing and evaluating a method for systematically integrating the behavioral trust results into the development of a computing system and its value.     

CATEGORIZE THEN CHOOSE: BOUNDEDLY RATIONAL CHOICE AND WELFARE

We propose a boundedly rational model of choice where agents categorize alternatives before choosing. The model explains some behavioral anomalies, and it is fully characterized by a property of choice data: a categorizer can never exhibit certain patterns of “revealed preference reversals”. This model offers clues on the problem of making welfare judgements in the presence of boundedly rational agents.     

LEGAL STANDARDS,ENFORCEMENT, AND CORRUPTION

Stricter laws require more incisive and costlier enforcement. Because enforcement activity depends both on available tax revenue and the honesty of officials, the optimal legal standard of a benevolent government is increasing in per capita income and decreasing in officials' corruption. In contrast to the “tollbooth view” of regulation, the standard chosen by a self‐interested government is a non‐monotonic function of officials' corruption, and can be either lower or higher than that chosen by a benevolent regulator. International evidence on environmental regulation shows that standards correlate positively with per‐capita income, and negatively with corruption, consistent with the model's predictions for benevolent governments.

Controlling the size of multivariate outlier tests with the MCD estimator of scatter

Multivariate outlier detection requires computation of robust distances to be compared with appropriate cut-off points. In this paper we propose a new calibration method for obtaining reliable cut-off points of distances derived from the MCD estimator of scatter. These cut-off points are based on a more accurate estimate of the extreme tail of the distribution of robust distances. We show that our procedure gives reliable tests of outlyingness in almost all situations of practical interest, provided that the sample size is not much smaller than 50. Therefore, it is a considerable improvement over all the available MCD procedures, which are unable to provide good control over the size of multiple outlier tests for the data structures considered in this paper.     

A Note on the Inoperability Input-Output Model

In this note, we propose some comments and some extensions of the inoperability input-output model (IIOM), as recently proposed by Santos and Haimes (2004). In particular, we propose the use of some analytic tools capable of providing information on the reaction of sectors subsequent to a terrorist attack on infrastructure service sectors. These tools, namely, the field of influence and the multiplier product matrix, provide information on the way sectors react to a shock on the aggregate demand and/or to a (temporary or permanent) change of production function coefficients. Finally, using the 2003 65 sectors input-output matrix for the U.S. economy, a simple empirical example is presented.
