Multivariate volatility forecasts for stock market indices

Volatility forecasts aim to measure future risk and they are key inputs for financial analysis. In this study, we forecast the realized variance as an observable measure of volatility for several major international stock market indices and accounted for the different predictive information present in jump, continuous, and option-implied variance components. We allowed for volatility spillovers in different stock markets by using a multivariate modeling approach. We used heterogeneous autoregressive (HAR)-type models to obtain the forecasts. Based an out-of-sample forecast study, we show that: (i) including option-implied variances in the HAR model substantially improves the forecast accuracy, (ii) lasso-based lag selection methods do not outperform the parsimonious day-week-month lag structure of the HAR model, and (iii) cross-market spillover effects embedded in the multivariate HAR model have long-term forecasting power.     

Minnesota-type adaptive hierarchical priors for large Bayesian VARs

Large Bayesian VARs with stochastic volatility are increasingly used in empirical macroeconomics. The key to making these highly parameterized VARs useful is the use of shrinkage priors. We develop a family of priors that captures the best features of two prominent classes of shrinkage priors: adaptive hierarchical priors and Minnesota priors. Like adaptive hierarchical priors, these new priors ensure that only ‘small’ coefficients are strongly shrunk to zero, while ‘large’ coefficients remain intact. At the same time, these new priors can also incorporate many useful features of the Minnesota priors such as cross-variable shrinkage and shrinking coefficients on higher lags more aggressively. We introduce a fast posterior sampler to estimate BVARs with this family of priors—for a BVAR with 25 variables and 4 lags, obtaining 10,000 posterior draws takes about 3 min on a standard desktop computer. In a forecasting exercise, we show that these new priors outperform both adaptive hierarchical priors and Minnesota priors.     

Self-enforcing international environmental agreements with a stock pollutant

In this paper the stability of an International Environmental Agreement (IEA) among N identical countries that emit a pollutant are studied using a two-stage game. In the first stage each country decides noncooperatively whether or not to join an IEA, and in the second stage signatories jointly against nonsignatories determine their emissions in a dynamic setting defined in continuous time. A numerical simulation shows that a bilateral coalition is the unique self-enforcing IEA independently of the gains coming from cooperation and the kind of strategies played by the agents (open-loop or feedback strategies). We have also studied the effects of a minimum participation clause finding that for this case a self-enforcing IEA just consists of the number of countries established in the clause.JEL Classification: C73, D62, Q28 Corresponding author : Santiago J.

财政透明化背景下的政府治理变革

财政透明度是民主社会中更为广泛的公众知情权和政府信息披露制度的重要组成部分。中国财政透明度同发达国家相比存在很大的差距，甚至落后于许多发展中国家。本文通过对财政透明度的基础理论分析，认为财政透明化作为政府治理变革的核心，对于政府治理效率的提高有积极性影响。为了适应经济全球化发展趋势，在更多领域内参与国际竞争与合作，就必须规范政府行为，实现政府治理再造，

Pure joint production and international trade: a note

This paper applies the principles of the neo-Ricardian (or Sraffian)theory of international trade to certain joint production systems.It is shown that, in contrast with single-product systems, (i)there is not always a pattern of international specialisation,which would entail the increase of the real wage rate in botheconomies, and (ii) the ‘law of comparative advantage’has no general validity. Furthermore, not only the existenceof such a pattern of specialisation but also the validity ofthis law depend on the values of the variables of distributionof income. The analysis is wholly based on two of the numericalexamples formulated by Bidard in 1997, and further generalisedin an elementary way only when this is considered necessary.
