Agricultural decline and sustainable development on mountain areas in Greece: Sustainability assessment of future scenarios

Agricultural decline may pose an important threat to mountain biodiversity but it also constitutes a driving force of socio-economic transformation. The aim of this study is to investigate the implications of alternative agricultural policy scenarios on the sustainable development of Greek mountain areas using a case study approach (Zagori region, Greece). Two agricultural policy scenarios were explored and assessed against a list of sustainability objectives. Causal relationships among drivers of changes and sustainability objectives were explored using Network Analysis. Our analysis has shown that agricultural liberalisation is expected to have devastating effects on the development of the area and it was strongly opposed as an alternative future by the local stakeholders. The analysis of the driver's causal relationship has also revealed that in order to ensure the sustainable development of the area it is necessary to sustain low input extensive farming, to promote mild tourism development and to enhance the operational efficiency of the National Park. Moreover, in order to reconcile agricultural decline, biodiversity and sustainable development, policy-management recommendations must be drawn at multiple administrative levels and complementary policy interventions within and between levels are required. It is thus, important that EU agricultural policies are complemented by national-regional interventions in order to regulate the fragile balance between agriculture and tourism. Finally, this study has shown that the combination of scenario analysis and sustainability assessment can provide an efficient tool to inform management strategies for sustainable development.     

Measuring Confucian values among East Asian consumers: a four country study

This study aims to make a conceptual and empirical contribution by developing and operationalizing suitable scales to capture certain Confucian values (face saving, humility, group orientation, hierarchy and reciprocity) that can influence East Asian consumers. Based on the pertinent literature, focus group discussions with extended East Asian families and East Asian scholar interviews, we develop and validate our measures on data from over 400 respondents across four East Asian cities (Tokyo, Hanoi, Beijing and Singapore). Despite some variance, our findings signal that East Asians are highly influenced by such traditional values. Several implications are extracted and future research directions suggested.     

Production risk in multi-output industries: estimates from Norwegian dairy farms

Farmers who produce multiple outputs are portfolio managers in the sense that they use inputs to balance expected economic return and variance of return. This article estimates the structure of the stochastic multioutput production technology in Norwegian dairy farming, allowing for a more flexible specification of the technology than previous studies. We find that an increase in input levels leads primarily to higher output variability, and that inputs also influence the covariance of shocks between outputs. Risk reducing effects of inputs on outputs are primarily present in the covariance functions. Technical change leads to shifts in the profit distribution over the data period, but no welfare improvement for risk averse farmers.     

Forecasting with preliminary data: a comparison of two methods

This study examines two alternate methods, a vector autoregression error correction model and a state space model, to forecast revised United States trade balance figures. Both these methods incorporate preliminary and revised trade data. The results obtained from these methods were compared to the benchmark forecasts generated by revised-data-only models. This Study finds that the state space model performs worse than the benchmark. The vector autoregression model performs better than the benchmark only in the one-step forecast. These results indicate that incorporating preliminary data may not be useful in forecasting the revised data.     

Corporate income tax and futures hedging

Our research is motivated by the Corn Products vs. Arkansas Best Supreme Court decisions that pitched the controversy of the tax treatment of gains and losses from futures hedging. The use of futures contracts as risk management tools depends on the tax code. In this paper we address complications in the current tax code that allow for asymmetric offset: Ordinary losses can be applied against capital gains; however, capital losses cannot by applied against ordinary gains. Also we consider the issue of tax loss carryover. We investigate the optimal hedge ratios under these scenarios analytically where possible, and numerically where necessary.

Are options redundant? Further evidence from currency futures markets

This paper investigates the impact of the introduction of options on the underlying asset's price formation process, using Geweke feedback measures. We derive the feedback measures from the Deutsche Mark, British Pound, Swiss Franc, Japanese Yen and Canadian Dollar futures and spot prices, before and after the introduction of options for these currency futures. While each currency market maintains some distinct characteristics in the post-option period, a common theme is found: after the option introduction, the instantaneous feedback between spot and futures markets improves drastically. The feedback from the spot to the futures market tends to decrease and remains small. The feedback from the futures market to the spot market tends to decrease as well. These results confirm the dominance of options markets, probably due to their smaller transaction costs. When made available, options assume a leading role for information transmission in currency markets.     

Risk and risk management in organic and conventional cash crop farming in Norway

This study presents empirical insight into organic and conventional cash crop farmers' perceptions of risk and risk management strategies, and identifies socio-economic variables linked to these perceptions. The data originate from a questionnaire survey of farmers in Norway. The results indicate that organic farmers perceived themselves to be less risk averse than conventional farmers. For both groups, crop prices and yield variability were the two top rated sources of risk, followed by institutional risks. The two groups evaluated risk management strategies quite similarly; favoured strategies were good liquidity and to prevent and reduce crop diseases and pests. The farmers' evaluation of sources of risk and choice of risk strategies depended on various socio-economic variables. The importance of institutional risks implies that policy makers should be cautious about changing policy capriciously and they should consider strategic policy initiatives that give farmers more long-term reliability.     

An empirical analysis of the relationship between hedge ratio and hedging horizon using wavelet analysis

In this article, optimal hedge ratios are estimated for different hedging horizons for 23 different futures contracts using wavelet analysis. The wavelet analysis is chosen to avoid the sample reduction problem faced by the conventional methods when applied to non‐overlapping return series. Hedging performance comparisons between the wavelet hedge ratio and error‐correction (EC) hedge ratio indicate that the latter performs better for more contracts for shorter hedging horizons. However, the performance of the wavelet hedge ratio improves with the increase in the length of the hedging horizon. This is true for both within‐sample and out‐of‐sample cases. © 2007 Wiley Periodicals, Inc. Jrl Fut Mark 27:127–150, 2007
