This paper explores the direct effects and spillovers of unconventional monetary and exchange rate policies. We find that official purchases of foreign assets have a large positive effect on a country’s current account that diminishes considerably as capital mobility rises. There is an important additional effect through the lagged stock of official assets. Official purchases of domestic assets, or quantitative easing (QE), appear to have no significant effect on a country’s current account when capital mobility is high, but there is a modest positive impact when capital mobility is low. The effects of purchases of foreign assets spill over to other countries in proportion to their degree of international financial integration. We also find that increases in US bond yields are associated with increases in foreign bond yields and in stock prices, as well as with depreciations of foreign currencies, but that all of these effects are smaller on days of US unconventional monetary policy announcements. We develop a theoretical model that is broadly consistent with our empirical results and that highlights the potential usefulness of domestic unconventional policies as responses to the effects of foreign policies of a similar type. 相似文献

We study men's adult mortality and longevity by socio-occupational status during industrialization in Saguenay-Lac-Saint-Jean, Quebec. Data were extracted from the BALSAC database (Université du Québec à Chicoutimi), which comprehensively traces the demographic history of the region since the beginning of the French Canadian settlement in 1840 up to the early 1970s. Using five occupational classes and controlling for year, age at marriage, urban/rural residence, and literacy, we found no evidence for the emergence of a socioeconomic gradient in mortality. At least until the early 1970s, mortality in the region is the lowest for farmers and appears to be driven by occupational risk rather than fundamental social causes. 相似文献

AbstractCertain elicitation techniques exert some control on expert opinions by leading them to a consensus or to a specific choice. In the absence of such guidelines, experts rely on their own knowledge to formulate opinions. This can result in large dispersions and affects the decision maker’s judgment. In this situation, we wonder what the relevant elicitation techniques are and how we can help experts to express their knowledge. From literature review, it is hard to decide if elicitation techniques are equivalent or not, which justifies the reproducibility analysis that we carry out in this paper. In this study, multiple experts have been involved in order to predict the defect size in hydraulic turbines, according to four proposed elicitation techniques. The comparison between these techniques was performed based on a suggested algorithm using the area metric concept. Our Findings show that elicitation techniques with ‘support’ tend to limit variations between experts and might be suitable only when prior knowledge on the expected elicited variable is available. Otherwise, we can end up with a distorted opinion of the elicited variable and an erroneous risk assessment. 相似文献

Many countries are promoting biofuels as a substitute for scarce oil. This paper develops a dynamic model of land allocation between food and energy and shows how the model can be calibrated using standard optimization techniques. Some possible implications of the trade-offs between food and energy are discussed. Specifically, we show that the effect of mandates is mainly felt through increased land conversion, which increases indirect carbon emissions Crude oil prices do not decrease significantly because of leakages. 相似文献

If collateral for bank loans is scarce and, if as a result, access to secured loans is restricted, the allocation of resources is inefficient. In anticipation of future borrowing constraints, individuals over-invest in collateralized types of capital, and consume and invest inefficiently low levels while they are borrowing constrained. The dual counterpart of this misallocation of resources is inefficiently low interest rates. In this situation, bank reserves play a positive welfare role by adding liquidity to the economy and by increasing not only bank lending rates, but also, paradoxically, bank deposit rates. As a result, in economies with scarce collateral the optimal reserves–requirement ratio is positive. 相似文献

This paper analyzes the stability and fluctuations of the exchange rate with a speculative bubble using the methods of evolutionary
finance and stochastic differential equations. It constructs a hybrid stochastic system for the financial market involving
a discrete time process and a continuous time process. The discrete process models the bubble and is meant to capture the
behavior of less sophisticated investors who trade infrequently. The continuous time process is a stochastic differential
equation for monetary policy together with a backward stochastic equation for the exchange rate. Monetary policy is affected
by the bubble and in turn affects the exchange rate as well as speculation. The bubble and exchange rate exhibit a form of
bifurcation. This means the bubble and exchange rate experience fluctuations as the propensity to chase trends or switch predictors
changes. 相似文献

Most macroeconomic models imply that faster income growth tends either to lower a country’s trade balance by raising its imports with little change to its exports or to reduce its terms of trade in order to maintain balanced trade. Krugman (1989 ) proposed a model in which countries grow by producing new varieties of goods. In his model, faster‐growing countries are able to export these new goods and maintain balanced trade without suffering any deterioration in their terms of trade. This paper analyzes the growth of US imports from different source countries and finds strong support for Krugman’s model. 相似文献

This paper exploits the unique experimental setting created by nearly 1,300 new single stock futures listings on the OneChicago exchange between 2003 and 2009. I investigate the impact of derivatives introductions on the tightness of short sale constraints facing their underlying assets. After controlling explicitly for supply and demand conditions in the stock lending market, this experiment reveals a precipitous decline in active utilization rates and loan fees in the lending market, after the futures introductions. The paper provides strong evidence that supports the view that derivatives represent a viable alternate synthetic short selling venue relaxing short sale constraints facing their underlying assets. 相似文献
