Capital's commodity frontiers strategy has at once woven together regional differences within an expanding world‐system and remade the productive and reproductive activities of humans and the rest of nature. The development of successive commodity frontiers gave way to long waves of economic expansion that have been pivotal to accelerating accumulation and transcending capital's recurrent crises. In short, commodity frontiers are constitutive of world‐ecological moments premised on booms and crises of accumulation. In this paper, I examine the coal commodity frontier in Appalachia, to illustrate the region's history as one of succeeding frontiers in and out of the region over the long twentieth century of American capitalism. I argue that the origin of Appalachia's coal frontier was decisively made through the nineteenth‐century agricultural revolution expressed outside of the region. Appalachia's full‐fledged development was an outcome of capital's under‐reproduction strategies. The crisis of the region's frontier turned on a lack of surplus from under‐reproduction strategies, competing coal basins, economic diversification and competing energy sources. I find that the commodity frontier concept not only illuminates regional political economies and ecologies of difference, but also explains the production of nature of historical capitalism.  相似文献

ABSTRACT

Based on the theoretical foundation of emotion regulation, this exploratory study aimed to examine changes in tourists’ perceived well-being and to determine whether these changes were due to use of emotion regulation strategies (ERSs) during their vacation. This study used travel diaries to record tourists’ use of ERSs on a daily basis, and also measured tourists’ perceived well-being one day before and after their vacation. Results indicated that tourists had significantly higher perceptions of well-being after vacation, and those who used ERSs were more likely to indicate a higher sense of well-being after vacation. The results provide new insight into which aspects of tourists’ subjective and psychological well-being can be boosted by taking vacations and how these aspects may be enhanced by using different ERSs.  相似文献

In this paper we discuss how repetition of a single statement affects its perceived credibility. Using an experimental design, our results support previous psychological studies on the “truth-effect”, which have shown that repeated messages are considered more credible than non-repeated messages. In addition, our study sheds light on the unanswered question why the truth-effect vanishes or reverses if statements are repeated too often. Analysis strongly points to a parallel, indirect negative effect, caused by participants showing reactance as a consequence of repetition.  相似文献

The scarcity of talent is a tremendous challenge for firms in the globalized world. This paper investigates the role of labor market imperfection in open economies for the usage of talent in the production process of firms. For this purpose, I set up a heterogeneous firms model, where production consists of a continuum of tasks that differ in complexity. Firms hire low‐skilled and high‐skilled workers to perform these tasks. How firms assign workers to tasks depends on factor prices for the two skill types and the productivity advantage of high‐skilled workers in the performance of complex tasks. I study the firms’ assignment problem under two labor market regimes, which capture the polar cases of fully flexible wages and a binding minimum wage for low‐skilled workers. Since the minimum wage lowers the skill premium, it increases the range of tasks performed by high‐skilled workers, which enhances the stock of knowledge within firms to solve complex tasks and reduces the mass of active firms. In a setting with fully flexible wages trade does not affect the firm‐internal assignment of workers to tasks. On the contrary, if low‐skilled wages are fixed by a minimum wage, trade renders high‐skilled workers a scarce resource and reduces the range of tasks performed by this skill type with negative consequences for the human capital stock within firms. In this case, trade leads to higher per‐capita income for both skill types and thus to higher welfare in the open than in the closed economy, whereas – somewhat counter‐intuitive – inequality between the two skill types decreases, as more low‐skilled workers find employment in the production process.  相似文献

In this article, we combine two so far separate strands of the economic literature and argue that democratization leads to a real exchange rate appreciation. We test this hypothesis empirically for a sample of countries observed from 1980 to 2007 by combining a difference‐in‐difference approach with propensity score matching estimators. Our empirical results reveal a strong and significant finding: democratization causes real exchange rates to appreciate. Consequently, the ongoing process of democratization observed in many parts of the world is likely to reduce exchange rate distortions.  相似文献

We examine the implications of separating students of different grade levels across schools for the purposes of educational production. Specifically, we find that moving students from elementary to middle school in 6th or 7th grade causes significant drops in academic achievement. These effects are large (about 0.15 standard deviations), present for both math and English, and persist through grade 8, the last year for which we have achievement data. The effects are similar for boys and girls, but stronger for students with low levels of initial achievement. We instrument for middle school attendance using the grade range of the school students attended in grade 3, and employ specifications that control for student fixed effects. This leaves only one potential source of bias–correlation between grade range of a student's grade 3 school and unobservable characteristics that cause decreases in achievement precisely when students are due to switch schools–which we view as highly unlikely. We find little evidence that placing public school students into middle schools during adolescence is cost-effective.  相似文献

Existing studies have shown how the royal wardrobe, the king's personal administrative office, regularly handled between a quarter and a half of the Crown's annual cash income. Despite this, the financial contribution of the wardrobe to royal finance under Henry III is not fully understood. For a reign in which debates about royal fiscal strategies are so notable a feature, this represents a significant gap. This article will supplement existing studies of wardrobe finance under Henry III by collectively analysing all 15 of the king's wardrobe accounts that are enrolled on the exchequer pipe rolls. The article makes two important findings. Firstly, the wardrobe was financially strong when the period of baronial reform began in 1258. Secondly, the wardrobe's financial strength was the result of a new, and deliberate, approach to acquiring revenue beyond the treasury that targeted sources of income that could generate cash quickly. During Henry's final years, this included greater reliance on credit. These findings suggest Henry III was not incapable of making adroit financial decisions. They also reveal that the foundations for the financial system developed by the three Edwards, which was more reliant on credit and sources of ready cash, were laid under Henry III.  相似文献

Using two newly available ultrahigh-frequency datasets, we investigate empirically how frequently one can sample certain foreign exchange and U.S. Treasury security returns without contaminating estimates of their integrated volatility with market microstructure noise. Using the standard realized volatility estimator, we find that one can sample dollar/euro returns as frequently as once every 15 to 20 s without contaminating estimates of integrated volatility; 10-year Treasury note returns may be sampled as frequently as once every 2 to 3 min on days without U.S. macroeconomic announcements, and as frequently as once every 40 s on announcement days. Using a simple realized kernel estimator, this sampling frequency can be increased to once every 2 to 5 s for dollar/euro returns and to about once every 30 to 40 s for T-note returns. These sampling frequencies, especially in the case of dollar/euro returns, are much higher than those that are generally recommended in the empirical literature on realized volatility in equity markets. The higher sampling frequencies for dollar/euro and T-note returns likely reflect the superior depth and liquidity of these markets.  相似文献

This paper proposes a model to conduct macro stress test of credit risk for the banking sector based on scenario analysis. We employ an original bank-level data set that splits bank credit portfolios in 21 granular categories, covering household and corporate loans. The results corroborate the presence of a strong procyclical behavior of credit quality, and show a robust negative relationship between the logistic transformation of non-performing loans (NPLs) and GDP growth, with a lag response of up to three quarters. The results also indicate that the procyclical behavior of loan quality varies across credit types. This is novel in the literature and suggests that banks with larger exposures to highly procyclical credit types and economic sectors would tend to undergo sharper deterioration in the quality of their credit portfolios during an economic downturn. Lack of sufficient portfolio granularity in macro stress testing fails to capture these effects and thus introduces a source of bias that tends to underestimate the tail losses stemming from the riskier banks in a system.  相似文献
