Technological change and wage premiums: historical evidence from linked employer-employee data
2013
Abstract This study analyses the impacts of a technological change (the steam engine) on wage premiums. Using historical employer–employee panel data, we found that steam technology had both new skill-demanding and skill-replacing aspects. The former manifested itself as an increase in the demand for high-skilled engineers, the latter in a decline in the demand for intermediate-skilled, able-bodied seamen and an increase in the demand for unskilled engine room operators. Our panel data analysis, which controls for unobserved heterogeneity, implies that high-skilled labourers in abstract tasks and unskilled labourers in manual tasks improved their wage positions relative to intermediate-skil…
Sanctions and the exit from unemployment in two different benefit schemes
2016
This paper investigates the effect of benefit sanctions on the exit rate from unemployment using a unique set of rich register data on unemployed Finnish individuals. The timing-of-events approach is applied to distinguish between the selection and causal effects of sanctioning. The results imply that the effect of sanctions differs according to the benefits received. Sanctions encourage unemployed individuals receiving flat-rate labour market support (LMS) to find jobs, whereas unemployed individuals receiving earnings-related (UI) allowances to leave the labour force. The encouraging effect of sanctions on active labour market policy programmes is relatively small and statistically signif…
Gender differences in ultimatum games: Despite rather than due to risk attitudes
2012
Abstract We analyze experimental data obtained from an ultimatum game framed as a situation of employee–employer negotiation over salaries. Parallel to this, we elicit subjects’ risk attitudes. In the existing literature, it has often been conjectured that gender differences in strategic environments are partly due to differences in risky decision making. Our evidence suggests that both gender and risk-related effects co-exist in ultimatum bargaining. However, differences in risk attitudes cannot explain gender effects in ultimatum bargaining.
Peer Discipline and Incentives Within Groups
2014
We investigate how a collusive group can sustain non-Nash actions by enforcing internal discipline through costly peer punishment. We give a simple and tractable characterization of schemes that minimize discipline costs while preserving incentive compatibility. We apply the model to a public goods contribution problem. We find that if the per-capita benefit from the public good is low, then regardless of whether peer discipline is feasible or not only small groups will contribute to the good. If the public good benefit is significant but peer discipline is infeasible it remains the case that only small groups contribute. On the other hand, if the public good benefit is significant but peer…
Correlation, hierarchies, and networks in financial markets
2010
We discuss some methods to quantitatively investigate the properties of correlation matrices. Correlation matrices play an important role in portfolio optimization and in several other quantitative descriptions of asset price dynamics in financial markets. Specifically, we discuss how to define and obtain hierarchical trees, correlation based trees and networks from a correlation matrix. The hierarchical clustering and other procedures performed on the correlation matrix to detect statistically reliable aspects of the correlation matrix are seen as filtering procedures of the correlation matrix. We also discuss a method to associate a hierarchically nested factor model to a hierarchical tre…
Alimentare sogni, destrutturare speranze. Politiche di offerta e dinamica della domanda di gioco aleatorio nell’Italia contemporanea
2013
I dati sul coinvolgimento degli italiani nel consumo di giochi di tipo alea (gambling in genere, scommesse, lotterie ecc.) evidenziano come negli ultimi dieci anni la pratica della “scommessa” sia diventata oltremodo diffusa. A questa crescita ha certamente contribuito, oltre alla crisi congiunturale richiamata da alcuni studiosi quale causa contingente, sia l‘aumento dell’offerta di gioco, cresciuta notevolmente rispetto al passato e in Italia fondamentalmente gestita dal monopolio statale, sia la maggiore accessibilità consentita dalle nuove tecnologie della comunicazione. Nell’intervento si descrive lo stato attuale della domanda e dell’offerta del consumo di gioco, prendendo in consider…
Structural contagion and vulnerability to unexpected liquidity shortfalls
2012
This paper assumes that financial fluctuations are the result of the dynamic interaction between liquidity and solvency conditions of individual economic units. The framework is an extention of Sordi and Vercelli (2012) designed as an heterogeneous agent model which proceeds through discrete time steps within a finite time horizon. The interaction at the micro-level between economic units monitors the spread of contagion and systemic risk, producing interesting complex dynamics. The model is analysed by means of numerical simulations and systemic risk modelling, where local interaction of units is captured and analysed by the bilateral provision of liquidity among units. The behaviour and e…
An assessment of the 2011 Spanish pension reform using the Swedish system as a benchmark
2013
AbstractThe aim of this paper is to make an assessment of the 2011 reform of the public pension system in Spain using the Swedish pension system as a benchmark, although some reference to the US pension system is also made. The paper focuses on the reform, explaining its aims, breaking down the main contents, critically examining the official view and describing the expected ageing of the Spanish population. This approach complements the quantitative analyses performed by other researchers and will enable us to assess the reformed system with the focus on four main areas: actuarial fairness, actuarial transparency, solvency and communication with the public. The main conclusion is that the …
Endogenous R&D Symmetry in Linear Duopoly with One-way Spillovers
2005
A duopoly model of cost reducing R&D-Cournot market competition is extended to encompass endogenous timing of R&D investments. Under the assumption that R&D spillovers are zero under simultaneous choices of R&D and only flow from the R&D leader to the follower under sequential choices, sequential and simultaneous play at the R&D stage are compared in order to assess the role of technological externalities in stimulating or attenuating endogenous firm asymmetry. The only timing structure of the R&D stage sustainable as subgame–perfect Nash equilibrium involves simultaneous play and thus zero spillovers.
Interbank lending and the spread of bank failures: A network model of systemic risk
2012
We model a stylized banking system where banks are characterized by the amount of capital, cash reserves and their exposure to the interbank loan market as borrowers as well as lenders. A network of interbank lending is established that is used as a transmission mechanism for the failure of banks through the system. We trigger a potential banking crisis by exogenously failing a bank and investigate the spread of this failure within the banking system. We find the obvious result that the size of the bank initially failing is the dominant factor whether contagion occurs, but for the extent of its spread the characteristics of the network of interbank loans are most important. These results ha…
