The rapid expansion of cocoa production on the Indonesian island of Sulawesi over the last decade surprised the world, not least because it came mainly from smallholders This paper examines government policies that have affected the subsector, and identifies issues it faces. The study concludes that the following factors contributed to the expansion, the availability of suitable land; low production costs; a highly competitive marketing system (a result of the government s policy of limited intervention), relatively good transport infrastructure, favourable macroeconomic policies, and smallholder entrepreneurship. It is particularly important that Indonesia s government left cocoa marketing and distribution free of many of the interventions applied to other commodities. Because of the competitive marketing system, the farmgate price of cocoa in Indonesia is very high relative to the export price Issues that must be addressed if cocoa is to develop further include product quality, the ‘adding-up’ problem, pest control and VAT. 相似文献

This paper proposes a new method to a bond portfolio problem in a multi-period setting. In particular, we apply a factor allocation
approach to constructing the optimal bond portfolio in a class of multi-factor Gaussian yield curve models. In other words,
we consider a bond portfolio problem in terms of a factors’ allocation problem. Thus, we can obtain clear interpretation about
the relation between the change in the shape of a yield curve and dynamic optimal strategy, which is usually hard to be obtained
due to high correlations among individual bonds. We first present a closed form solution of the optimal bond portfolio in
a class of the multi-factor Gaussian term structure model. Then, we investigate the effects of various changes in the term
structure on the optimal portfolio strategy through series of comparative statics. 相似文献

This empirical study examines the degree to which non-pecuniary factors affect work incentives by monetizing their value. Although the literature has acknowledged the importance of non-pecuniary factors, the problem of measuring their effectiveness in influencing work incentives has persisted. Using survey data collected from employees, the analyses are intended to elicit aspects of work relations in the real labor market that are difficult to study using laboratory experiments. Our analyses underscore the importance of favorable non-pecuniary factors as affecting work incentives. The results of the analyses also reveal some patterns related to the relative importance of non-pecuniary factors across countries. Irrespective of the country, self-motivated devices have a greater impact on work effort than hospitality-based approaches do. In addition, employees in countries with higher GDP consider non-pecuniary factors more highly than employees in countries with lower GDP do. 相似文献

This paper examines an equilibrium growth model in which production activities generate environmental pollution that has a negative welfare effect and in which individual households' subjective discount rate is a function of individual consumption, which is internal to each household, and of total pollution, which is an external factor to the individual agents. It is shown that there may exist multiple steady states and that the dynamic equilibrium may display indeterminacy, depending on the properties of the discount-rate function, the pollution-capital relationship in production technology, and the pollution-consumption relationship in instantaneous utility. The long-run effects of tighter environmental policy are subsequently examined, and the results are also found to be dependent on the above factors. 相似文献

Abstract We explore a small open economy with overlapping generations to show that demographic structure is an important factor for the determination of a production pattern in the dynamic trade theory. In the representative agent model, Baxter (1992) shows that even if there are two commodities and two production factors, there is a Ricardian implication that opening up to trade leads to perfect specialization in a small open economy. In contrast, using the overlapping generations model, we find that the heterogeneity of the economic agents generally makes imperfect specialization occur. We also find that whether the stability condition holds or not is crucial for the determination of the long-run production pattern. 相似文献

This paper proposes a new approximation method for pricing barrier options with discrete monitoring under stochastic volatility environment. In particular, the integration-by-parts formula and the duality formula in Malliavin calculus are effectively applied in pricing barrier options with discrete monitoring. To the best of our knowledge, this paper is the first one that shows an analytical approximation for pricing discrete barrier options with stochastic volatility models. Furthermore, it provides numerical examples for pricing double barrier call options with discrete monitoring under Heston and λ-SABR models. 相似文献

This paper presents a two-country model in which two currencies compete with each other. There exists an equilibrium in which the two currencies with different rates of inflation circulate as media of exchange despite neither currency being required to be used for transactions. Taxes payable in local currency and asymmetric injection of fiat money by the government through purchases of a certain good generate demands even for the currency with a higher inflation rate. In such an equilibrium, the government that issues the currency with a lower rate of inflation collects seigniorage not only from its own residents but from the residents of the other country provided that the rate of inflation is positive. The strong currency in the sense of a low inflation rate becomes an international medium of exchange. Policy games, in which the two governments simultaneously choose and commit to tax rates and inflation rates, are also examined. We show, among other things, that the equilibrium rate of inflation is zero in this policy game. In other words, unlike a common argument, the rate of inflation does not go below zero. This result is due to the fact that a negative rate of inflation induces a negative amount of seigniorage andvice versa. Some alternative currency regimes are examined. Even for a country with a weak currency, abandonment of its currency leads to a lower level of welfare. Monetary unions are briefly discussed as well.J. Japan. Int.

Now that China's "re-emergence" as a world center of production is obvious, concerns about its implications are being raised throughout the world, in general, and particularly in East Asia. China's economic growth is nothing but spectacular. If all parties are rational, however, a peaceful rise for China is possible. Peaceful management of the Taiwan Strait is critical in this respect. There are two possible scenarios for the peaceful rise of China: a unilateralist China in the multipolar world of competition, and a multilateralist, postmodern China embedded in an East Asian community. It is in the interest of Japan, the United States and other countries in the international society to induce China to take the latter scenario. To realize this goal, efforts on the part of China are critical, but the efforts of other countries such as the United States and Japan are also very important. 相似文献
