The French wholesale market is set to expand in the next few years under European pressure and national decisions. In this article, we assess the forecasting ability of several classes of time-series models for electricity wholesale spot prices at a day-ahead horizon in France. Electricity spot prices display a strong seasonal pattern, particularly in France, given the high share of electric heating in housing during winter time. To deal with this pattern, we implement a double temporal segmentation of the data. For each trading period and season, we use a large number of specifications based on market fundamentals: linear regressions, Markov-switching (MS) models and threshold models with a smooth transition. An extensive evaluation on French data shows that modelling each season independently leads to better results. Among nonlinear models, MS models designed to capture the sudden and fast-reverting spikes in the price dynamics yield more accurate forecasts. Finally, pooling forecasts give more reliable results. 相似文献

The aim of this paper is to complement the minimum distance estimation–structural vector autoregression approach when the weighting matrix is not optimal. In empirical studies, this choice is motivated by stochastic singularity or collinearity problems associated with the covariance matrix of impulse response functions. Consequently, the asymptotic distribution cannot be used to test the economic model's fit. To circumvent this difficulty, we propose a simple simulation method to construct critical values for the test statistics. An empirical application with US data illustrates the proposed method. 相似文献

This paper documents a robust empirical regularity: in the long-run, higher trade openness is associated with a lower structural rate of unemployment. We establish this fact using: (i) panel data from 20 OECD countries, (ii) cross-sectional data on a larger set of countries. The time structure of the panel data allows us to control for unobserved heterogeneity, whereas cross-sectional data make it possible to instrument openness by its geographical component. In both setups, we purge the data of business cycle effects, include a host of institutional and geographical variables, and control for within-country trade. Our main finding is robust to various definitions of unemployment rates and openness measures. Our benchmark specification suggests that a 10 percentage point increase in total trade openness reduces aggregate unemployment by about three quarters of one percentage point. 相似文献

Evaluating the carbon-macroeconomy relationship: Evidence from threshold vector error-correction and Markov-switching VAR models 总被引:1,自引:0,他引:1

This paper studies the nonlinear adjustment between industrial production and carbon prices – coined as ‘the carbon-macroeconomy relationship’ – in the EU 27. We model carbon price returns and industrial production as nonlinear and state-dependent, with dynamics depending on the sign and magnitude of past realization of returns and the growth of industrial production. Our findings show that (i) macroeconomic activity is likely to affect carbon prices with a lag, due to the specific institutional constraints of this environmental market; (ii) the joint dynamics of industrial production and carbon prices seem adequately captured by two-regime threshold vector error-correction and two-regime Markov-switching VAR models compared to linear models as main competitors. The regime-switching models proposed are profoundly checked for their economic content and statistical congruency, and are found to provide a sound statistical framework for a comprehensive analysis of the carbon-macroeconomy relationship. 相似文献

We explore the social capital impacts of a community-driven development project in the Philippines in which communities competed for block grants for infrastructure investment. The analysis uses a unique panel data set of about 2100 households, aggregated at the village-level, collected in 66 treatment and 69 comparison communities. We provide both difference-in-differences and propensity score matching estimates. We find that the project increased participation in village assemblies and the frequency with which local officials meet with residents and had a negative impact on collective action. There is also more limited evidence of a positive impact of the project on bridging (i.e., generalized) trust and of a negative impact on group membership. 相似文献

Building upon a formerly performed study on port competitiveness, this article discusses the use of a stochastic frontier
model as an interesting novel use to test, identify and correct respondents’ bias by applying it to competitiveness analysis
based on perceptions of senior executives. Measuring the importance of competition determinants of seaports, conventionally
analyzed using a SWOT-analysis based on (transport) infrastructure as a prime requirement for port activity growth, is an
important issue to port management. However, it seems that the “institutional” environment of a seaport is also critical in
obtaining a competitive advantage. In Haezendonck et al. (2000 and 2001) those port specific advantages and disadvantages
were identified using factor analysis and L1-regression on the perceptions of 75 respondents, all senior executives and experts,
through a survey. As regards the results of this study, critiques were formulated on the use of perceptions, often biased
due to the political lobbying potential of the results. Since respondents often see independent studies as an opportunity
to obtain more or early government subsidies, attract new investment projects or at least highlight the attention on their
specific problems and demands, they were prone to underestimating the positive impact of the key success factors of the studied
seaport compared to its main rivals, in this case major seaports in the so-called Hamburg–Le Havre competitive range. The
purpose of this article is to test the assumption that respondents significantly underestimate the positive impact of port
specific advantages and to see which of the respondent subgroups within the 75 respondents sample are more responsible than
others for this underestimation. In addition, we argue and demonstrate that the use of a stochastic frontier method is appropriate
for this matter. Each of 25 considered competition determinants of the original study is decomposed into a noise and “efficiency”
term, based on the Bayesian stochastic frontier model (BSFM). In this article, we find evidence that BSFM could be used to
test the “lobby-effect” or underestimation of the real effect of determinants, that terminal operators as a subgroup of respondents,
are more likely to underestimate the key success factors than the subgroup of port experts and that those determinants that
are directly related to government action show more underestimation than competitiveness determinants that result from private
investments. 相似文献

In this article, we provide statistical evidence around jumps affecting commodity returns. Using nearly 20 years of daily data, we use Laurent, Lecourt, and Palm's (2011) methodology to jump extraction, and discuss various aspects of the estimated jump activity. On average across various commodity markets, we find a high number of days for which returns exhibit the presence of jumps, consistently with the intuition that commodities are affected by large price fluctuations. We emphasize that the post-jump average return depends on the commodity sector considered (e.g. agriculture, energy, or metals). We also show evidence of a jump-to-volatility channel for commodities (similar to the effect usually found for equities). Finally, we diagnose around 40 dates during which commodity indices, stocks, bonds and currencies `co-jump’, revealing a tail dependence between standard and alternative assets. 相似文献

The correlation among multiple lines of business plays a critical role in aggregating claims and thus determining loss reserves for an insurance portfolio. We show that the Sarmanov family of bivariate distributions is a convenient choice to capture the dependencies introduced by various sources, including the common calendar year, accident year, and development period effects. The density of the bivariate Sarmanov distributions with different marginals can be expressed as a linear combination of products of independent marginal densities. This pseudo-conjugate property greatly reduces the complexity of posterior computations. In a case study, we analyze an insurance portfolio of personal and commercial auto lines from a major U.S. property-casualty insurer. 相似文献

This paper studies a risk measure inherited from ruin theory and investigates some of its properties. Specifically, we consider a value-at-risk (VaR)-type risk measure defined as the smallest initial capital needed to ensure that the ultimate ruin probability is less than a given level. This VaR-type risk measure turns out to be equivalent to the VaR of the maximal deficit of the ruin process in infinite time. A related Tail-VaR-type risk measure is also discussed. 相似文献
