Tracking, monitoring and steering the evolution of public debt over time will be a major policy challenge for almost all governments in the advanced countries in the years to come, in particular for those belonging to the European Monetary Union. In this paper I study public debt dynamics in a two-country monetary union where a representative, risk-averse wealth-owner optimizes his/her portfolio of sovereign bonds issued in the common currency. I obtain two main results with respect to the standard country-by-country approach. First, the interest-rate spread between the two countries is endogenized as the higher-debt country pays a risk premium which is proportional to the level of its own debt with respect to the debt of the other. Second, its debt dynamic path becomes nonlinear and dependent on the evolution of the other country’s debt. The most important policy implication is that “dynamic interdependence” is not fully considered in the implementation of EMU fiscal rules, but it may may jeopardize their goal of convergence and stability of debt stocks. 相似文献
Are firm entry and fixed exporting costs relevant for understanding the international transmission of business cycles? We revisit this question using a model that includes entry, selection to exporting activity, physical capital accumulation and endogenous labor supply. We determine that once the stochastic process for exogenous productivity is calibrated to consider the endogenous dynamics in TFP created by the number of firms and the time series volatility of entry is calibrated to the data, our model yields minimal departures from the Backus et al. (1992) benchmark. The richer model shares all of the successes of the previous model in terms of the volatilities of aggregate quantities, as well as its failures, in terms of replicating patterns of international co-movement and the volatility of international relative prices. 相似文献
The recent financial crisis has highlighted the need to go beyond a purely micro approach to financial regulation and supervision. As a consequence, the number of policy speeches, research papers and conferences that discuss a macro perspective on financial regulation has grown considerably. The policy debate is focusing in particular on macroprudential tools and their usage, their relationship with monetary policy, their implementation and their effectiveness. Macroprudential policy has recently also attracted considerable attention among researchers. This paper provides an overview of research on this topic. We also identify important future research questions that emerge from both the literature and the current policy debate. 相似文献
We use a version of the Global Projection Model covering the United States, Euro area and Japan to assess options for dealing with the looming risk of international deflation. The zero floor to interest rates constrains monetary policy. Confidence intervals, derived from stochastic simulations, indicate ranges of uncertainty. The results suggest a high probability of a declining price level for a couple of quarters in 2009. Suitable policy adaptations reduce the risk that this might turn into a prolonged, global deflation. These include: a price level path target for monetary policy, which would respond to previous, as well as expected, shortfalls from the desired inflation rate; a more stimulative fiscal policy; and an increase in the long-run target for inflation. 相似文献
This paper applies data envelopment analysis (DEA) to assess technical efficiency in a big public university. Particular attention has been paid to two main activities, teaching and research, and on two large groups, the Science and Technology (ST) sector and the Humanity and Social Science (HSS) sector. The findings, based to data from 2005 to 2009, suggest that the ST sector is more efficient in terms of quality of research than the HSS sector, that instead achieves higher efficiency in teaching activities. The efficiency estimates strongly depend on the output specification, given that the use of several quality proxies, such as three research and two student questionnaire-based teaching alternative indices, reduce performance and its differentials for both research and teaching activities. A bootstrap technique is also used to provide confidence intervals for efficiency scores and to obtain bias-corrected estimates. The Malmquist index is calculated to measure changes in productivity. 相似文献
This article provides new evidence on the contribution of local banking to local economic growth (i.e. at county level – the Italian ‘province’) in Italy. A comprehensive data set is used, which includes control variables for social capital and human capital as well as indicators of the quality of local infrastructures and the production structure of the local economy. A linear within-estimator technique with fixed effects is applied to a modified version of the so-called Barro regression in order to address the well-known econometric issues of reverse causality and estimation bias resulting from unobserved district-specific influences. 相似文献
The long-term growth in the air transport is leading to the need to expand airport infrastructure but this has serious environmental implications. Thus, there is the need to establish an alternative to the traditional airport pricing structure for landing fees, which reflects the overall costs that air transport operators impose on others. Airport pricing should provide a sound guide for future investments, and at the same time reflect whether additional facilities are needed and at what price, by taking into account all costs, including environmental costs. This paper analyses one application of Ramsey Pricing on uncongested Spanish airport, by considering the CO2 emission costs as a valuable input. 相似文献
In this work we explore how the international outsourcing of production impacts the skill composition of employment within Italian manufacturing firms. In particular, our aim is to assess whether the choice to offshore production activities to cheap‐labour countries implies a bias in the employment of skilled workers relative to unskilled ones.
Using a balanced panel of firms covering the period 1995–2003, we set up a counterfactual analysis in which, by using a difference‐in‐differences propensity score matching estimator, we compare the dynamics of skill demand for treated and control firms while addressing the possible problem of selection bias.
Our results identify a ‘potential’ skill bias effect of production offshoring. In particular, we find that treated firms tend to show an upward shift in the skill ratio with respect to the counterfactual sample, but coefficients are not significantly different from zero. When we look at the elements of the skill ratio separately, we find that the skill bias is driven by a fall in the employment of production workers (blue collars), rather than by the increase in the employment of non‐production workers (white collars), thus providing further evidence on the unskilled labour‐saving nature of international outsourcing. 相似文献
In contingent valuation studies, observed behavioral choices often enter as independent variables in the willingness to pay function. However, these variables may be endogenously determined when the error term in the behavioral model is correlated with the error term in the willingness to pay model. We investigate the effects of correcting for the endogeneity of a variable, namely membership status in environmental organizations that proxies unobservable characteristics of the respondents. Jointly modeling the membership variable and the willingness to pay response yields an estimate for the effect of the former that contradicts previous findings but is intuitive and agrees with theoretical expectations. 相似文献
