The advanced countries are now going through the worst crisis since the Depression, but today's dominant current theories and econometric models proved unable to predict the crisis. The paper investigates whether the financial instability hypothesis of Hyman P. Minsky offers a better explanation. Minsky argued that in a period of economic growth and tranquility economic agents are more prone to take risk, and banks are more willing to finance borrowers. Meanwhile, in the course of the boom over-indebtedness and financial innovations make the financial system more fragile, and more exposed to adverse effects. We show that both these effects made themselves felt in the subprime loan crisis. Specifically, the main determinants of the crisis have been the increasing appetite for risk and financial innovations. So, we conclude that, although this crisis differs in some of its features from previous crashes and from Minsky's account, the mechanisms underscored by Minsky were and are nevertheless at work. 相似文献

We develop and test a fast and accurate semi‐analytical formula for single‐name default swaptions in the context of a shifted square root jump diffusion (SSRJD) default intensity model. The model can be calibrated to the CDS term structure and a few default swaptions, to price and hedge other credit derivatives consistently. We show with numerical experiments that the model implies plausible volatility smiles. 相似文献

ABSTRACT 1 : The paper studies the determinants of regular volunteering, taking its cue from the previous literature on extrinsic and intrinsic motivations. Its main contribution lies in the analysis of the role of monetary rewards in influencing intrinsic motivation. It uses frameworks that allow empirical hypotheses to be made about the effects of monetary rewards, intrinsic motivation and the combined term on volunteer labour supply. With an Italy‐based survey, the paper shows, controlling for endogenous bias, that monetary payments as well as intrinsic motivation have roles in the real‐life decision to supply volunteer work, but monetary rewards do not crowd out intrinsic motivation. 相似文献

This paper uses network analysis to study how employment intermediaries have influenced inter-firm worker mobility in a region of Italy, in response to a 1997 reform that introduced temporary employment agencies. Worker reallocations from a matched employer-employee dataset are mapped onto a directed graph where the vertices are firms and the links denote transfers of workers between firms. Temporary employment agencies significantly improve network integration and practicability, while rapidly increasing the control over mobility channels. The trade off inherent in intermediation activity is captured and discussed. The potential of network analysis as a tool for monitoring regional labor markets is highlighted. 相似文献

We consider a two-sided, finite-horizon search and matching model with heterogeneous types and complementarity between types. The quality of the pool of potential partners deteriorates as agents who have found mutually agreeable matches exit the market. When search is costless and all agents participate in each matching round, the market performs a sorting function in that high types of agents have multiple chances to match with their peers. However, this sorting function is lost if agents incur an arbitrarily small cost in order to participate in each round. With a sufficiently rich type space, the market unravels as almost all agents rush to participate in the first round and match and exit with anyone they meet. 相似文献

The article assesses the stabilization effects of the EU import regime for fresh fruit and vegetables based on the entry price system (EPS). The analysis is carried out on the EU prices of tomatoes and lemons and those of imports from some of the main competing countries on the EU domestic markets: Morocco, Argentina, and Turkey. It is based on the estimation of a threshold vector autoregressive econometric model that is shown capable of taking the workings of the import regime into account. The model shows that prices behave differently when import prices are above/below the trigger entry price. This article allowed to highlight the cases for which the isolation effect of EPS seems reached and the resulting stabilization effects. 相似文献

The paper assesses the causal relationship between formal volunteering and individual health. The econometric analysis employs data provided by the Income and Living Conditions Survey for the United Kingdom carried out by the European Union’s Statistics (UK-SILC) in 2006. Based on 2SLS, treatment effect and recursive bivariate probit models, and religious participation as instrument variable, and controlling for social and cultural capital, our results show a positive effect of formal volunteering on self-perceived health. 相似文献

Credit default swap calibration and derivatives pricing with the SSRD stochastic intensity model 总被引:1,自引:0,他引:1
We introduce the two-dimensional shifted square-root diffusion (SSRD) model for interest-rate and credit derivatives with (positive) stochastic intensity. The SSRD is the unique explicit diffusion model allowing an automatic and separated calibration of the term structure of interest rates and of credit default swaps (CDSs), and retaining free dynamics parameters that can be used to calibrate option data. We propose a new positivity preserving implicit Euler scheme for Monte Carlo simulation. We discuss the impact of interest-rate and default-intensity correlation and develop an analytical approximation to price some basic credit derivatives terms involving correlated CIR processes. We hint at a formula for CDS options under CIR + + CDS-calibrated stochastic intensity.Received: March 2004, Mathematics Subject Classification (2000):

ABSTRACTThe link between social relations and psychological wellbeing is well established in sociological and mental health studies. Since the beginning of the 2000s, this link has been garnering new attention and interest in economic and public health studies. Almost twenty years of empirical studies testing this relationship have established contrasting results for two main reasons. First, the majority of the studies are based on cross-sectional data, leaving out endogeneity and heterogeneity problems; second, mental health measurements are often discordant from each other. This study investigates the relationship between structural social capital and individual self-rated mental health using five waves of the British Household Panel Survey from 1991 to 1995 (unbalanced panel N = 44,684). We take into account the heterogeneity and endogeneity issues and implement fixed effects and lag-dependent variable estimations. Moreover, we used different methodologies to measure mental health as a robustness check. Our findings show the existence of a negative relationship between being both a member of and active in an organization and worse mental health. In addition, being active within an organization in the previous year has a negative effect on worse mental health in the following year. 相似文献
