We present results on undiscounted optimal policies in the Leontief two‐sector growth model with durable capital. Unlike the results with a labour intensive consumption goods sector, we show that a monotonic optimal programme is only one special case out of many richer possibilities of transition dynamics. Depending on the initial capital stock, and a key parameter ζ that could be interpreted as a marginal rate of transformation of capital between today and tomorrow, an optimal programme may converge to a period‐two cycle; and even when it converges to the golden rule stock, it can do so (damped) cyclically or with a “jump”. 相似文献

This paper examines the small-sample performance of spatial HAC (SHAC) estimators of the standard errors on parameters. We find that, in small to moderately-sized datasets, the use of HAC estimators may be recommended only with a relatively large degree of cross-sectional interdependence. 相似文献

This paper explores the performance impacts and benefits of the adoption of Social Enterprise Software (SES). SES forms a nested innovation, given that its adoption requires an already established infrastructure of Information and Communication Technology. To control for induced sample selection, we use a two-step estimation procedure. Based on German firm-level data our results confirm that firms which use business-to-business (B2B) e-commerce applications are more likely to adopt SES. The estimated correlations also provide weak evidence for complementarity between B2B e-commerce and SES. We show that two measures of firm performance, i.e. sales and labor productivity, are highest for firms using SES and B2B e-commerce applications in conjunction. 相似文献

What is the effect of offering agents an option to delay their choices in a global coordination game? We address this question by considering a canonical binary action global game, and allowing players to delay their irreversible decisions. Those that delay have access to accurate private information at the second stage, but receive lower payoffs. We show that, as noise vanishes, as long as the benefit to taking the risky action early is greater than the benefit of taking the risky action late, the introduction of the option to delay reduces the incidence of coordination failure in equilibrium relative to the standard case where all agents must choose their actions at the same time. We outline the welfare implications of this finding, and probe the robustness of our results from a variety of angles. 相似文献

While the capital structure irrelevance proposition is the point of departure in corporate finance, it is unknown if debt‐or‐equity decisions matter to farm producer organizations. To inform decisions of capital acquisition, a panel study is conducted to estimate the relationships of different types of debt (current, long‐term) and equity (allocated, unallocated) to the financial performance of 707 farm producer organizations in the United States during the 2005–2011 period. Using 3,120 observations, the panel analysis indicates net sales in period t is increased by $1.97, $9.59, and $4.01 with an addition of $1 in current debt, allocated equity, or unallocated equity in period t‐1. Furthermore, the magnitude of the positive relationship of an additional dollar of allocated (unallocated) equity to net income is estimated at $0.32 ($0.14). We thus reject the notion managers and directors of farm producer organizations should decide to use debt or equity with a coin toss. 相似文献

This paper examines an informed principal-agent game with ex post participation constraints for the agent. It shows that the players do not lose by communicating in turn among themselves rather than simultaneously if and only if the principal communicates first. It then considers every Bayesian incentive compatible allocation rules that assign non-negative payoffs for one player in a bilateral asymmetric information framework. It provides necessary and sufficient conditions for sequential communication to be as efficient as simultaneous communication in implementing these allocation rules when the player with unbounded payoffs moves first. 相似文献

Hausman (1978) developed a widely-used model specification test that has passed the test of time. In this paper, we show that the asymptotic variance of the difference of the two estimators can be a singular matrix. Three illustrative examples are used, namely an exogeneity test for the linear regression model, a test for the Box–Cox transformation, and a test for sample selection bias. 相似文献

Fiji signed the United Nations 2015 target of halving extreme poverty from its 1990 level, but like many developing countries it is facing challenges in meeting this goal. This paper presents the economic modelling using Fiji's Household Income and Expenditure Survey 2002/03 dataset to examine the economic and social factors crucial for poverty reduction. Two hypotheses are tested: first, we estimate the monetary effects of education at the aggregate and disaggregated returns to education (primary, secondary, tertiary levels) and by income quartiles, and second, test the non-monetary education and health factors as channels of impact promulgated as effects against poverty prevalence. The monetary results indicate that all income quartile households (i.e. lowest to highest) benefit from additional skills obtained through formal education. While those at the lowest income quartile in particular benefit the most from formal education, however it cannot sustainably prevent people with only primary education from falling into poverty. The results for non-monetary models show that education has a positive and significant influence on the tendency of the people to engage in health prevention activities and in acquiring good housing facilities. 相似文献

This paper studies the role of information about uncertain input prices for a competitive firm. The production decision has to be taken when the price of an input factor is perceived as random. However, a signal is observable in advance, conveying some information about the future factor price. Transparency is linked to the informational content of this signal. The impact of a higher level of transparency is analyzed from an ex ante perspective, i.e. before the information signal is observed. The change of factor use, production amount and cost are determined by comparing the strength of the curvatures of total and marginal product. By contrast, ex ante profit always increases, independently of the shape of the production function. 相似文献
