We use a factor model and elastic net shrinkage to model a high-dimensional network of European credit default swap (CDS) spreads. Our empirical approach allows us to assess the joint transmission of bank and sovereign risk to the nonfinancial corporate sector. Our findings identify a sectoral clustering in the CDS network, where financial institutions are in the center and nonfinancial entities as well as sovereigns are grouped around the financial center. The network has a geographical component reflected in different patterns of real-sector risk transmission across countries. Our framework also provides dynamic estimates of risk transmission, a useful tool for systemic risk monitoring.  相似文献

Growth in the current-dollar sales of agricultural machinery and equipment was almost six percent per annum during 2000-2005.1 This was much faster than the 2.6 percent growth for agricultural output and the 1.2 percent rate for population in the same period. JEL Classification L64  相似文献

World demand for heating, ventilating, and air-conditioning (HVAC) equipment is expected to rise in absolute terms during the current five-year period, but the rate of growth is slowing. However, growth is still in excess of that recorded by both global building construction expenditures and world gross domestic product. In 2007, $63.1 billion was spent on HVAC. The Asia-Pacific region now accounts for about 45 percent of the total. The two major categories of HVAC are cooling equipment, which accounts for 71 percent of the total, while heating equipment is responsible for the remaining 29 percent. The commercial market dominates the residential market by a ratio of 65:35. There are hundreds of suppliers around the world, but the eight leading firms have about 50 percent of the market.  相似文献

World demand for refractory products—heat-resisting ceramic materials used in metal refining, glass making, and other high-temperature industrial applications—will be slowing down considerably from an annual rate of 10.8 percent during 2002–07 to 3.5 percent during 2007–12. Such slower growth reflects many factors, but is due primarily to: unsettled economic conditions; better efficiencies in steelmaking (which accounts for about half of all end uses of refractories); and the preference of end-users for maintenance rather than new facilities. The four key markets or end uses for refractory materials are: iron and steelmaking; other metal-making; nonmetallic materials such as glass; and an all-other category. In 2007, world refractory demand was 38.1 million metric tons valued at $22.9 billion; the corresponding figures for 2012 are projected at about 45.2 million metric tons valued at $28.5 billion. The Asia-Pacific region accounted for about 45 percent of total weight in 2007; its share by 2012 should rise to about 69 percent, with China becoming the dominant producer and consumer of refractory materials.  相似文献

Exchange Rate Pass-Through and Rivalry in the Swiss Automobile Market. —This paper investigates the pricing rivalry among foreign automobile producers in the Swiss market. The main results from the dynamic analysis of two categories of automobiles between 1977 and 1991 are: First, the degree of exchange rate pass-through differs among source-countries despite the absence of quantitative restrictions on imports and of domestic production facilities. However, for some countries, pricing strategies show remarkable consistency across product categories and time spans. Second, the degree of exchange rate pass-through is low, especially in the market for small-size automobiles. Third, this low degree of pass-through may be attributed to a low degree of competition among foreign sellers.  相似文献

This essay reviews the international human rights standards that the Human Rights Watch Report uses as standards for judgment, summarises with some commentary the Report’s major findings and recommendations, comments more fully on certain findings and recommendations, and, in conclusion, raises several issues that need to be addressed given the state of freedom of association and other related human rights in the USA.  相似文献
