This article analyses co‐movements in a wide group of commodity prices during the time period 1992–2010. Our methodological approach is based on the correlation matrix and the networks inside. Through this approach we are able to summarize global interaction and interdependence, capturing the existing heterogeneity in the degrees of synchronization between commodity prices. Our results produce two main findings: (a) we do not observe a persistent increase in the degree of co‐movement of the commodity prices in our time sample, however from mid‐2008 to the end of 2009 co‐movements almost doubled when compared with the average correlation; (b) we observe three groups of commodities which have exhibited similar price dynamics (metals, oil and grains, and oilseeds) and which have increased their degree of co‐movement during the sampled period. 相似文献

This paper demonstrates a time-series production technique to quantify the deer harvest and deer hunting benefits of controlled burns or prescribed fire. The time series regression model showed a statistically significant and positive effect of prescribed fire on deer harvest. The net economic value of the resulting additional deer hunting benefit was estimated using the Contingent Valuation Method at $ 98 per additional deer harvested. The initial deer hunting benefits of an additional 1,000 acres of prescribed burning are between $ 2,674 and $ 3,128 or $ 2-3 per acre. The costs of prescribed burning greatly exceed these benefits, suggesting that deer hunting benefits represent only a small part of the multiple use benefits of prescribed fire. 相似文献

We study the dynamics of inflation persistence in 45 countries for the period 1960–2008 using a recently developed test for multiple changes in persistence, which decomposes the sample information between adjacent I (0) and I (1) periods. We find that: (i) inflation persistence and average inflation tend to fall and rise at the same time; (ii) in some countries there are changes in the level of inflation which do not seem to be related to changes in inflation persistence; (iii) around half of the countries analyzed do not present any burst of I (1) behavior, and hence have stationary inflation throughout; (iv) for the other half, we detect switches of the type I (0) ? I (1) ? I (0), hence, inflation persistence, when it has occurred, has been temporal; and, (v) for about half of the countries in which inflation has presented I (1) behavior, persistent inflation lasted more than a decade. In addition, we find that in the last 50 years there have been mainly two episodes where long bursts of I (1) inflation took place simultaneously among groups of countries. In general, the “Great Inflation” occurred during the seventies and eighties in advanced economies, whereas it occurred during the eighties and nineties in emerging economies, particularly in Latin America. 相似文献

Most studies on skill transferability focus on the return to capabilities developed in the initial job and disregard the different characteristics of the origin and the destination industries. In contrast, this article assesses the borders of skill transferability by comparing the return to skills for firm stayers, firm changers in the same industry, and firm changers to other industries. Based on a sample of Portuguese employees in retail banking, our results confirm significant inter‐firm and inter‐industry skill transferability. Difference‐in‐differences estimates with propensity score matching show that firm switchers benefit from a wage premium compared to firm stayers. However, the wage premium drops sharply when movers leave the banking sector. 相似文献

Informality is a defining characteristic of labour markets in developing and transition countries. This paper analyzes patterns of mobility across different forms of formal and informal employment in Russia. Using the Russian Longitudinal Monitoring Survey household panel we estimate a dynamic multinomial logit model with individual heterogeneity and correct for the initial conditions problem. Simulations show that structural state dependence is weak and that transition rates from informal to formal employment are not lower than from non-employment. These results lend support to the integrated view of the labour market. 相似文献

The concern for the existence of solution to the Walras - Cassel model is usually dated at the beginning of the 1930s, and one decade later the proof of existence of utility function. Ugo Broggi, however, posed both issues in 1923 and 1919, respectively, and even hinted at modern ways of solving them. He was an outstanding mathematician, a former disciple of David Hilbert and collaborator with the Giornale degli Economisti. Broggi's achievements are also linked to a critical reading of Osorio's treatise on Paretian economics. 相似文献

Shifts in Portfolio Preferences of International Investors: An Application to Sovereign Wealth Funds
We develop a dynamic general equilibrium model to analyze the macroeconomic effects of a shift in portfolio preferences of foreign investors. The model has two countries and two asset classes (equities and bonds). It is characterized by imperfect substitutability between assets and allows for endogenous adjustment in interest rates and asset prices. To illustrate the mechanics of the model, we calibrate it to analyze a transfer of reserves from central banks to sovereign wealth funds (SWFs). We look separately at two diversification paths: a shift away from dollar assets (path 1), and a shift away from US bonds to US equities (path 2). In path 1, the dollar depreciates and US net debt falls on impact and increases in the long run. In path 2, the dollar depreciates and US net debt increases in the long run. 相似文献

This study sets out to explore variation in the consumer choice structure in relation to three types of products with different levels of search, experience and credence attributes. The decision structures of rice, wine and functional food (experience, search and credence products) consumers were explored by means of laddering. The results suggest the presence of an emotional component in foods that increases in complexity (becomes more abstract) with the number of credence attributes. The findings recommend adjusting the complexity of advertising campaigns and product positioning to the type of product being promoted. 相似文献
