Effects of the euro on trade, capital markets and the international monetary system

The implications of the introduction of the euro undoubtedly reach far beyond Europe. How will the rest of the world be affected? What role will the euro play as an international trading, investment and reserve currency? Will it be able to function as a stabilising element in the international monetary system?     

Dynamic Hedging Effectiveness in South Korean Index Futures and the Impact of the Asian Financial Crisis

This paper focuses on the impact of the 1997 Asian financial market crisis upon hedging effectiveness within the KOSPI 200 stock index and index futures markets. The paper utilizes the inter-temporal relationship between the two markets to examine the characteristics of several minimum variance hedge ratios. It also examines the performances of alternative hedging strategies for dynamic portfolio management in the presence of cointegrated time-varying risks. The results show a decline in the persistence of conditional volatility within market prices after the crisis. This decline leads to the relative performance of utilizing constant hedge ratios to increase, though not significantly so to guarantee a superior performance over more sophisticated time-varying hedge ratio strategies.     

Fair valuation of cliquet-style return guarantees in (homogeneous and) heterogeneous life insurance portfolios

Participating life insurance contracts allow the policyholder to participate in the annual return of a reference portfolio. Additionally, they are often equipped with an annual (cliquet-style) return guarantee. The current low interest rate environment has again refreshed the discussion on risk management and fair valuation of such embedded options. While this problem is typically discussed from the viewpoint of a single contract or a homogeneous* insurance portfolio, contracts are, in practice, managed within a heterogeneous insurance portfolio. Their valuation must then – unlike the case of asset portfolios – take account of portfolio effects: Their premiums are invested in the same reference portfolio; the contracts interact by a joint reserve, individual surrender options and joint default risk of the policy sponsor. Here, we discuss the impact of portfolio effects on the fair valuation of insurance contracts jointly managed in (homogeneous and) heterogeneous life insurance portfolios. First, in a rather general setting, including stochastic interest rates, we consider the case that otherwise homogeneous contracts interact due to the default risk of the policy sponsor. Second, and more importantly, we then also consider the case when policies are allowed to differ in further aspects like the guaranteed rate or time to maturity. We also provide an extensive numerical example for further analysis.     

The intra‐day price discovery process between the Singapore Exchange and Taiwan Futures Exchange

This paper focuses on the increasing competition between exchanges for listing similar index futures contracts and the impact this has on information dissemination between various markets. Specifically, using both the Hasbrouck and Gonzalo–Granger methodologies for extracting the information content held in each market, a comparison of information efficiencies between the Singapore Exchange and the Taiwan Futures Exchange is examined for Taiwan Index Futures listed in both markets. The results show not only a common stochastic trend between index futures and their underlying indices, but also provide strong evidence to suggest price discovery primarily originates from the Singapore futures market. There are direct implications of this result for both financial exchanges and traders—in particular, that traders realize price determination can arise from both futures markets, and the need for exchanges to maintain a reputation as an information center for these similarly traded financial instruments. © 2002 John Wiley & Sons, Inc.

Export variety and export performance: Empirical evidence for the OECD countries

Export Variety and Export Performance: Empirical Evidence for the OECD Countries. — Does product variety matter for export performance? This has been suggested by the new trade theory. In the present paper, we investigate empirically whether increasing export variety has contributed to the export growth of the OECD countries. We calculate direct measures of export variety and estimate pooled export demand equations for 15 OECD countries. The econometric results suggest that producing highly differentiated export goods gives a competitive advantage which allows to sell more products.     

Local Currency Pricing versus Producer Currency Pricing: Direct Evidence from German Exporters

Abstract. In new open-economy macroeconomic models, the assumption on the pricing behavior of firms in international trade plays a central role. Whether firms apply producer currency pricing (PCP) or local currency pricing (LCP) crucially affects, for example, the design of optimal monetary policy or the choice of the optimal exchange rate system. However, empirical evidence has so far been mixed and is furthermore mostly of an indirect nature. This paper draws direct evidence on the price-setting behavior of German exporters from a questionnaire-based survey. We find that PCP applies in more integrated markets. Differences between LCP firms and PCP firms mainly exist with respect to the use of mark-ups and in the validity of the law of one price for their respective products.     

Identifying the balance sheet and the lending channels of monetary transmission: A loan-level analysis

We make a novel attempt at comparing the strength of the lending and balance sheet channels of monetary transmission. To make this comparison, we use loan-level data to determine how borrower balance sheets and bank liquidity are related to bank lending decisions and how monetary policy can affect these relationships. The key innovation in this paper is the use of loan-level data. This enables us to measure the independent effects of the two channels and directly account for borrower balance sheets and lender liquidity instead of using proxies. Our results show that the balance sheet channel is the main mechanism through which monetary policy shocks are transmitted to the economy and that the lending channel does not play a significant role.     

The optimal-drift model: an accelerated binomial scheme

We introduce the optimal-drift model for the approximation of a lognormal stock price process by an accelerated binomial scheme. This model converges with order o(1/N), which is superior compared to today??s benchmark methods. Our approach is based on the observation that risk-neutral binomial schemes converge to the lognormal limit independently of the choice of the drift parameter. We verify the improved order of convergence by an asymptotic expansion of the binomial distribution function. Further, we show that the above result on drift invariance implies weak convergence of the binomial schemes suggested by Tian (in J. Futures Mark. 19, 817?C843, 1999) and Chang and Palmer (in Finance Stoch. 11, 91?C105, 2007).
