Buyer-seller relationships in international trade: Evidence from U.S. States' exports and business-class travel

International trade has become increasingly dependent on the transmission of complex information, often realized via face-to-face communication. This paper provides novel evidence for the importance of in-person business meetings in international trade. Interactions among trade partners entail a fixed cost of trade, but at the same time they generate relationship capital, which adds bilateral specific value to the traded products. Differences in the face-to-face communication intensity of traded goods, bilateral travel costs and foreign market size determine the optimal amount of interaction between trade partners. Using U.S. state level data on international business-class air travel as a measure of in-person business meetings, I find robust evidence that the demand for business-class air travel is directly related to volume and composition of exports in differentiated products. I also find that trade flows in R&D intensive manufactures and goods facing contractual frictions are most dependent on face-to-face meetings. The econometric identification exploits the cross-state variation in bilateral exports and business-class air travelers by foreign country and time period, circumventing any spurious correlation induced by cross-country differences driving aggregate travel and trade patterns.     

The role of banks in the Czech monetary policy transmission mechanism

With this work, I aim to enrich the knowledge about the monetary policy transmission mechanism in the Czech Republic with empirical evidence on the impact of monetary policy on bank lending. Using a panel of quarterly time series for Czech commercial banks for the period 1996–2001, I study the overall effect of monetary policy changes on the growth rate of loans and the characteristics of the supply of loans. The characterization of the credit market's supply side allows us to make inferences on the operativeness of the credit channel (the bank lending channel and the broad credit channel) of the monetary transmission mechanism. I find that changes in monetary policy alter the growth rate of loans, with considerably stronger magnitude in the period 1999–2001 than in the period 1996–1998. From the analysis intended to capture the characteristics of the supply of loans, I conclude that the lending channel was operative in the period 1996–1998: I find cross‐sectional differences in the lending reactions to monetary policy shocks due to the degree of capitalization and to liquidity. For the subsequent period 1999–2001, the results also show distributional effects of monetary policy due to bank size and its bank's proportion of classified loans. In the context of steadily decreasing interest rates, this can bolster the supposition of financial frictions between borrowers and lenders and hence, that of an operative broad credit channel.     

On expectations‐driven business cycles in economies with production externalities: A comment

Eusepi (2009, International Journal of Economic Theory 5, pp. 9–23) analytically finds that a one‐sector real business cycle model may exhibit positive co‐movement between consumption and investment when the equilibrium wage‐hours locus is positively sloped and steeper than the household’s labor supply curve. However, we show that this condition does not imply that expectations‐driven business cycles will emerge in Eusepi's model. Specifically, a positive news shock about future productivity improvement leads to an aggregate recession whereby output, employment, consumption and investment all fall in the announcement period.     

Taxation,redistribution, and observability in social dilemmas

In the presence of social dilemmas, cooperation is more difficult to achieve when populations are heterogeneous because of conflicting interests within groups. We examine cooperation in the context of a nonlinear common pool resource game, in which individuals have unequal extraction capacities and have to decide on their extraction of resources from the common pool. We introduce monetary and nonmonetary mechanisms in this environment. The two monetary mechanisms are tax extraction and redistribution of the tax revenue. These include a Pigovian per‐unit tax mechanism and an increasing block tax that only taxes units extracted above the social optimum. Another mechanism varies the observability of individual decisions. We find that the two tax and redistribution mechanisms reduce extraction, increase efficiency, and decrease inequality within groups. In contrast, observability impacts only the baseline condition by encouraging free‐riding instead of creating moral pressure to cooperate.     

A mixed C-vine copula model for hedging price and volumetric risk in wind power trading

When energy trading companies enter into long-term agreements with wind power producers, where a fixed price is paid for the fluctuating production, they are facing a joint price and volumetric risk. Since the pay-off of such agreements is non-linear, a hedging portfolio would ideally consist of not only forwards, but also a basket of e.g. call and put options. Illiquidity and an almost non-existent market for options challenge however the optimal hedging of joint price and volumetric risk in many market places. Here, we consider the case of the Danish power market, and exploit its strong positive correlation with the much more liquid German market to construct a proxy hedge. We propose a three-dimensional mixed vine copula to model the evolution of the Danish and German spot electricity prices and the Danish wind power production. We construct a realistic hedging portfolio by identifying various instruments available in the market, such as real options in the form of the right to transfer electricity across the border and the right to convert electricity to heat. Using the proposed vine copula to determine optimal hedging decisions, we show that significant benefits are to be drawn by extending the hedging portfolio with the proposed instruments.

Challenges for a broadband service strategy in rural areas: A Romanian case study

Broadband network deployment plays an important part in the strategic policies in Europe to promote growth and innovation in all sectors of the economy in addition to social and territorial cohesion. In compliance with existing community policies, Romanian strategies in this field seek to provide the necessary support for broadband connectivity in rural areas. The goal of this study is to define a rural end-user profile to plan the most appropriate broadband service strategy from both a technical and a marketing perspective. Our empirical research involves an exploratory survey conducted in rural areas in northwestern Romania (n=1040 respondents). The findings reveal low levels of customer satisfaction and users more interested in data transfer than voice or video applications. Given this rural user profile, simulations of network traffic were conducted. The simulation results suggest that WLANs are the most suitable solution for the “last mile” broadband segment.     

The influence of brand image and company reputation where manufacturers market to small firms: A customer value perspective

Branding research has largely focused on consumer goods markets and only recently has attention been given to business markets. In many business markets the company's reputation has a strong influence on buying decisions which may differ from the more specific product related influence of the brand's image. In this paper we investigate these differences by testing the hypotheses about the influences of brand image and company reputation on customers' perceptions of product and service quality, customer value, and customer loyalty in a business market where there are three manufacturers marketing their brands directly to a large number of small firms. The results indicate that the brand's image has a more specific influence on the customers' perceptions of product and service quality while the company's reputation has a broader influence on perceptions of customer value and customer loyalty.
