Export and hedging decisions under revenue and exchange rate risk: a note

Abstract This note analyzes optimal export and hedging decisions taken by a risk-averse exporting firm which simultaneously faces hedgeable exchange rate risk and non-hedgeable revenue risk abroad. The separation property does not hold, exports depend on preferences and expectations. Revenue uncertainty causes the firm to export less. The optimal currency forward position can be divided into three components: an expected revenue component, a speculative component and a revenue uncertainty component.

Hedging price risk when real wealth matters

This paper analyzes optimal hedging of a tradable risk (e.g. price risk or exchange rate risk) with forward contracts in the presence of untradable inflation risk. Utility is defined over real wealth. Optimal forward positions are derived relative to a given initial exposure in the tradable risk. A nominally unbiased forward market usually implies a non-zero real risk premium and hence some risk taking. If untradable inflation risk is a monotone function of the tradable risk plus noise, cross hedging and speculating on the real risk premium are conflicting objectives; the level of relative risk aversion determines which objective is dominant in a nominally unbiased forward market.

The Impact of Delivery Risk on Optimal Production and Futures Hedging

Multiple delivery specifications exist on nearly all commodity futures contracts. Sellers are typically allowed to choose among several grades of the underlying commodity. On the delivery day, the futures price converges to the spot price of the cheapest-to-deliver grade rather than to that of the par-delivery grade of the commodity. This imposes an additional delivery risk on hedgers. This paper derives the optimal production and futures hedging strategy for a risk-averse competitive firm in the presence of delivery risk. We show that, depending on its relative valuation, the delivery option may induce the firm to produce more than in the absence of delivery risk. If delivery risk is additively related to commodity price risk, the firm will under-hedge its exposure to commodity price risk. If delivery risk is multiplicatively related to commodity price risk, the firm will under- or over-hedge this exposure. For constant relative risk aversion, this is illustrated by a numerical example.

Exports and hedging exchange rate risks: the multi‐country case

This article examines the optimal production, export allocation, and hedging decisions of a risk‐averse international firm that exports to several foreign markets with different currencies. The firm faces multiple exchange rate risks. Optimal decisions are analyzed under two scenarios. In the first, there is a forward market for one currency only. Then, the export allocation to different markets is separable from the firms preferences and the joint distribution of the exchange rates. In contrast, total production is not separable except for a special case. In the second scenario, there is a forward market for each currency. Then, both production and export allocation are separable. Hedging with forward contracts depends on risk premia and on the joint distribution of the exchange rates. If tradable exchange rate risk is a linear function of untradable exchange rate risk plus noise, there is a conflict between cross hedging and taking a basis risk. If, alternatively, the untradable exchange rate risk is a linear function of the tradable exchange rate risk and noise, there is no such conflict. A speculative position in a biased forward market for one currency can be cross hedged using an unbiased forward market for another currency.

Socialist Heritage and the Opinion on Entrepreneurs: Micro-Level Evidence from Europe

What factors shape an individual’s opinion on entrepreneurs? How do these factors differ across countries? This paper analyzes the relationship between socialist history and individuals’ opinions on entrepreneurs. Using a large-scale micro-level dataset from 30 European countries, we find that individuals from countries with a socialist history have a more negative opinion on entrepreneurs. This negative effect is less pronounced for individuals that are younger, better educated and have self-employed parents. Our paper makes two contributions: First, it provides empirical evidence on the determinants of individuals’ opinion on entrepreneurs. Second, it contributes to the understanding of entrepreneurship in former socialist countries.

Restricted Export Flexibility and Risk Management with Options and Futures

This paper examines the production, export and risk management decisions of a risk-averse competitive firm under exchange rate risk. The firm is export flexible in allocating its output to either the domestic market or a foreign market after observing the exchange rate. Export flexibility is restricted by certain minimum sales requirements that are due to long-term considerations. Currency options are sufficient to derive a separation result under restricted export flexibility. Under fairly priced currency futures and options, full hedging with both instruments is optimal. Introducing fairly-priced currency options stimulates production provided that the currency futures market is unbiased.
