Pricing Reinsurance Contracts on FDIC Losses

This paper proposes a pricing model for the FDIC's reinsurance risk. We derive a closed‐form Weibull call option pricing model to price a call‐spread a reinsurer might sell to the FDIC. To obtain the risk‐neutral loss‐density necessary to price this call spread we risk‐neutralize a Weibull distributed FDIC annual losses by a tilting coefficient estimated from the traded call options on the BKX index. An application of the proposed approach yield reasonable reinsurance prices.     

The Effect of Regulatory Harmonization on Cross‐Border Labor Migration: Evidence from the Accounting Profession

The paper examines whether international regulatory harmonization increases cross‐border labor migration. To study this question, we analyze European Union initiatives that harmonized accounting and auditing standards. Regulatory harmonization should reduce economic mobility barriers, essentially making it easier for accounting professionals to move across countries. Our research design compares the cross‐border migration of accounting professionals relative to tightly matched other professionals before and after regulatory harmonization. We find that international labor migration in the accounting profession increases significantly relative to other professions. We provide evidence that this effect is due to harmonization, rather than increases in the demand for accounting services during the implementation of the rule changes. The findings illustrate that diversity in rules constitutes an economic barrier to cross‐border labor mobility and, more specifically, that accounting harmonization can have a meaningful effect on cross‐border migration.     

Financial Exposure and the International Transmission of Financial Shocks

This paper analyzes the transmission mechanism of banking sector shocks in an international real business cycle model with heterogeneous bank sizes. We examine to what extent the financial exposure of the banking sector affects the transmission of foreign banking sector shocks. In our model, the more exposed domestic banks are to the foreign economy via lending to foreign firms, the greater are the spillovers from foreign financial shocks to the home economy. The model highlights the role of openness to trade and the dynamics of the terms of trade in the international transmission mechanism of banking sector shocks: spillovers from foreign banking sector shocks are greater the more open the home economy is to trade and the less the terms of trade respond to foreign shocks.     

Shuttling Goods,Weaving Consumer Tastes: Informal Trade between Turkey and Russia

In ‘top down’ conceptualizations of globalization, people often enter the analytical picture merely as resisters to globalization or as receivers of corporate produced goods, messages and ideas. This article, in contrast, focuses on a process in which ‘ordinary’ people are the active makers of global processes and meanings. I describe the transnational trade network between post-Soviet countries and Turkey, in which Western fashions and images get circulated and transformed through the activities of informal entrepreneurs. I thus challenge accounts of globalization in which the dissemination of images is depicted as a top down process originating in corporations located in metropolitan countries. Based on ethnographic evidence collected in Istanbul and Moscow on the informal ‘shuttle trade’, I demonstrate that the mobility of ‘ordinary’ people across borders facilitates the flows of signs and images. Moreover, Western images and fashions get remoulded and acquire new meanings in the process of circulation.     

Firm Size and Wages in Germany – Trends and Impacts of Mobility

The analysis of firm-size wage differentials in Germany, using data from the German Socio-Economic Panel, firstly corroborates the finding that wages rise with firm-size and shows that the rank order of mean wages between firm-size classes is stable for the period 1984–1993. Secondly, the most important novel results are as follows: (i) wage differentials between firm-size classes increased during the period investigated after controlling for individual attributes and computing with deflated values; (ii) average levels of the qualification of employees have diverged noticeably between small and large firms; (iii) movers from small to larger firms have to accept wages below the average pay of incumbents with comparable attributes in the new firms: (iv) movers to smaller firms, however, retain a portion of their higher wages in larger firms; and (v) wage differentials between smaller and larger firms decline with increasing unemployment.     

Tradable and non-tradable expenditure and aggregate demand for imports in an emerging market economy

Using an assumption of non-separability of non-tradable expenditure from imports, this paper examines the impact of the structural transformation undertaken after 2001 on imports and, in turn, the current account stance of Turkey. In this regard, an import demand function is derived under the assumption of non-separability, and is estimated using quarterly time series data from Turkey. The empirical results show that the assumption of non-separability cannot be rejected in the case of Turkey and the relative prices of non-tradable and tradable goods must be among the determinants of import demand in addition to the relative price of imports and real GDP. This result accordingly implies that recent increases in import expenditure are, to some extent, due to changes in the relative price structure in favour of non-tradable goods.     

Price Discovery in Illiquid Markets: Do Financial Asset Prices Rise Faster Than They Fall?

We study price discovery in municipal bonds, an important OTC market. As in markets for consumer goods, prices “rise faster than they fall.” Round‐trip profits to dealers on retail trades increase in rising markets but do not decrease in falling markets. Further, effective half‐spreads increase or decrease more when movements in fundamentals favor dealers. Yield spreads relative to Treasuries also adjust with asymmetric speed in rising and falling markets. Finally, intraday price dispersion is asymmetric in rising and falling markets, as consumer search theory would predict.     

传统酱菜中降解亚硝酸盐枯草芽孢杆菌的筛选和鉴定

酱菜是我国传统风味的调味佳品,但在酱菜的生产过程中易产生大量的亚硝酸盐,因此从酱菜中分离、筛选出能降解亚硝酸盐的高效菌株尤为重要。本实验利用传统分离纯化方法从酱菜中筛选出的能高效降解亚硝酸盐的菌种,并通过现代分子生物学鉴定方法对其进行分析。结果表明,该筛选出的菌株具有一定的降解亚硝酸盐能力,通过分子生物学鉴定为枯草芽孢杆菌。研究为酱菜生产提供优质菌种资源奠定了一定的基础。
