This paper has the objectives of (a) comparing estimated willingness‐to‐pay (WTP) across three elicitation mechanisms (a Becker‐DeGroot‐Marschak [BDM] auction, a kth price auction, and a choice experiment [CE]) and (b) examining how these vary by participation fee. The product under consideration is kenkey made with nutritious maize, biofortified with vitamin A, which gives it a distinct orange color, in contrast to the white and yellow varieties that are traditionally consumed. We use an experiment consisting of 14 treatment arms, conducted in rural Ghana. Our estimation strategy explicitly accounts for the censored (typically at the market price) nature of the bids in the auctions, and the apparently lexicographic choices of several individuals in the CE. We find no evidence of economically meaningful (defined by the minimum currency unit of five pesewas) differences in WTP (although they may be statistically significant) across elicitation mechanisms, or by participation fee, a result that is in contrast to that found in much of the literature. A secondary finding is that the provision of nutrition information positively and significantly affects the marginal WTP for the new maize. 相似文献

Inflation dynamics and the cost channel of monetary transmission 总被引:2,自引:0,他引:2
Evidence from vector autoregressions indicates that the impact of interest rate shocks on macroeconomic aggregates can substantially be affected by the so-called cost channel of monetary transmission. In this paper, we apply a structural approach to examine the relevance of the cost channel for inflation dynamics in G7 countries. Since firms’ costs of working capital increase with interest rates, we augment a (hybrid) New Keynesian Phillips curve by including the short-run nominal interest rate. We find significant and varying direct interest rate effects for the majority of countries, including member countries of the EMU. Simulations further demonstrate that the estimated interest rate coefficients can substantially affect inflation responses to monetary policy shocks, and can even lead to inverse inflation responses, when the cost channel is - relative to the demand channel - sufficiently strong. 相似文献

Federal Reserve nonborrowed reserve supply systematically responded to changes in inflation and in the output gap over the period 1969-2000. While the feedback from output gap is always negative, the response of money supply to changes in inflation varies considerably across time. Nonborrowed reserves decreased with inflation in the post-1979 period and increased in the pre-1979 period. Applying a standard macro-model, the estimated reaction functions are shown to ensure equilibrium determinacy. Viewed through the money supply lens, Federal Reserve policy substantially changed over time, but has never allowed for endogenous fluctuations, which contrasts conclusions drawn from federal funds rate analyses. 相似文献

This paper empirically reexamines the hypothesis of a positive relationship between the inflation rate and its variability. The sample consists of 66 countries for the 1955–85 sample period. Using pooled cross-section time series data, empirical tests are performed for nine different country-groupings ranging from the G–7 developed countries to a group of 10 developing Asian countries. Several important conclusions can be derived. First, irrespective of the variability measure employed, the results indicate the presence of a significant positive relationship between the inflation rate and its variability. This provides strong support to Okun's hypothesis. Second, this relationship is stronger during the flexible rather than the fixed exchange rate period. Third, there appears to be an optimum zone of inflation rate within which the predictability of inflation is at its highest and hence uncertainty cost is at its lowest. For the 1955–85 sample period, this optimum zone of average inflation rate lies in the range of 5 to 7 percent. 相似文献

Modelling the dynamics,structural breaks and the determinants of the real exchange rate of Australia
Khorshed Chowdhury 《Journal of International Financial Markets, Institutions & Money》2012,22(2):343-358
This paper examines the dynamics, structural breaks and determinants of the real exchange rate (RER) of Australia derived from an inter-temporal general equilibrium model. Autoregressive Distributed Lag (ARDL) modelling results show that a one per cent increase in: (1) terms of trade appreciates the RER by 0.96–1.05 per cent in the long-run; (2) government expenditure appreciates the RER by 0.53–0.46 per cent in the long-run; (3) net foreign liabilities appreciates the RER by 0.18–0.22 per cent in the long-run; (4) interest rate differential depreciates the RER by 0.007–0.01 per cent in the long-run; (5) openness in trade depreciates the RER by 1.15–1.31 per cent in the long-run; and (6) per-worker labour productivity depreciates the RER by 0.38–0.55 per cent in the long-run. The two endogenously determined structural breaks are positive but are statistically insignificant. The speed of adjustment towards equilibrium is high with short-run disequilibrium correcting by nearly 39–47 per cent per quarter. These results add new insights to the literature on the determinants of RER in Australia. Apart from the terms of trade, the effects of other determinants of RER are contrary to the results obtained in previous studies. 相似文献

This article examines behavior in the two-player, constant-sum Colonel Blotto game with asymmetric resources in which players maximize the expected number of battlefields won. The experimental results support the main qualitative predictions of the theory. In the auction treatment, where winning a battlefield is deterministic, disadvantaged players use a “guerilla warfare” strategy that stochastically allocates zero resources to a subset of battlefields. Advantaged players employ a “stochastic complete coverage” strategy, allocating random, but positive, resource levels across the battlefields. In the lottery treatment, where winning a battlefield is probabilistic, both players divide their resources equally across all battlefields. However, we also find interesting behavioral deviations from the theory and discuss their implications. 相似文献

This study examines the impact of shocks to exchange rate and output uncertainty (volatility) on real private fixed investment (FI) in Canada, Germany, the United Kingdom and the United States. The analysis is conducted using vector autoregressive models that contain the price level, real output, the volatility of real output, the real exchange rate, the volatility of the real exchange rate, an interest rate and FI. The results yield important public policy implications with regard to the impact of output volatility of FI. Our analysis indicates that volatility shocks, measured as output volatility or exchange rate volatility, do not have a significant impact on FI for any country in our study. 相似文献

Economics 304KH and 304LH at The University of Texas at Austin are introductory honors economics courses. Our goal was to
provide students with more advanced material than available in introductory textbooks, such as a discussion of microeconomics
based on one‐dimensional calculus and a survey of macroeconomics based on economic models. The supplemental material consists
of Web course notes, on‐line quizzes, simulation and data modules and group interactive modules. This paper focuses on the
development of Web economic course materials. We discuss the difficulties of programming mathematical instructional material
in HTML and the coming solution in XML, JavaScript, and Java. The effectiveness of the on‐line course materials are also evaluated
based on student responses.
