Conclusions For our purposes here, the analysis has been fruitful in that it has served to indicate and underscore in both general and specific terms the sources and determinants of migration movement and the destination of migrants. The qualitative analysis and the statistical test have led to several research conclusions. Both United States and Ghanaian migrants behave in accordance with the migration concepts examined. Common relationships between migration and economic opportunity are apparent. While push factors have generally initiated migratory movement among black Americans, particularly in respect to the South, both groups tend to move to regions with better economic opportunities. In both cases, migration is a negative function of distance, and a large labor force at the origin is a stimulus to out-migration at the origin.  相似文献

Consumption and Portfolio Choice over the Life Cycle   总被引:13,自引:0,他引:13  
This article solves a realistically calibrated life cycle modelof consumption and portfolio choice with non-tradable laborincome and borrowing constraints. Since labor income substitutesfor riskless asset holdings, the optimal share invested in equitiesis roughly decreasing over life. We compute a measure of theimportance of human capital for investment behavior. We findthat ignoring labor income generates large utility costs, whilethe cost of ignoring only its risk is an order of magnitudesmaller, except when we allow for a disastrous labor incomeshock. Moreover, we study the implications of introducing endogenousborrowing constraints in this incomplete-markets setting.  相似文献

We match large U.S. corporations' tax returns during 1989–2001 to their financial statements to construct a firm‐level proxy of firms' use of off‐balance sheet and hybrid debt financing. We find that firms with less favorable prior‐period Standard & Poor's (S&P) bond ratings or higher leverage ratios in comparison to their industry report greater amounts of interest expense on their tax returns than to investors and creditors on their financial statements. These between‐firm results are consistent with credit‐constrained firms using more structured financing arrangements. Our within‐firm tests also suggest that firms use more structured financing arrangements when they enter into contractual loan agreements that provide incentives to manage debt ratings. Specifically, we find that after controlling for S&P bond rating and industry‐adjusted leverage, our sample firms report greater amounts of interest expenses for tax than for financial statement purposes when they enter into performance pricing contracts that use senior debt rating covenants to set interest rates. Furthermore, we find that the greatest book‐tax reporting changes occur when firms become closer to violating these debt rating covenants. These latter findings are consistent with firms' contractual debt covenants influencing their use of off‐balance sheet and hybrid debt financing.  相似文献

Bargaining is common in markets for heterogeneous goods and differences in bargaining power between buyer and seller affect the negotiated transaction price. Previous research has found systematic evidence in the housing markets that weak buyers pay higher prices and weak sellers receive lower prices for their homes. Earlier work has modeled the bargaining effect as a parallel shift in the hedonic function, implicitly assuming that attribute shadow prices were unaffected by the bargaining process. In this paper, we use a sample of home sales where the seller's bargaining power is weakened by the fact that the home is vacant at the time of sale to test whether the effect of bargaining is best captured by a shift in the hedonic constant or whether the attribute shadow prices vary as well. The question is significant for property valuation where estimation of the marginal value of an attribute is commonly used to adjust comparable sales data. We find strong confirmation that bargaining power influences the negotiated price. We also find evidence that bargaining power alters attribute prices, although we do not find a consistent pattern across markets.  相似文献

This study examines the association between activity-based costing and manufacturing performance. Results using a cross-sectional sample of manufacturing plants indicates that extensive ABC use is associated with higher quality levels and greater improvements in cycle time and quality, and is indirectly associated with manufacturing cost reductions through quality and cycle time improvements. However, on average, extensive ABC use has no significant association with return on assets. Instead, we find weak evidence that the association between ABC and accounting profitability is contingent on the plant's operational characteristics.  相似文献

This paper examines liquidity and quote clustering on the NYSE and Nasdaq using data after the two market reforms—the 1997 order–handling rule and minimum tick size changes. We find that Nasdaq–listed stocks exhibit wider spreads and smaller depths than NYSE–listed stocks and stocks with higher proportions of even–eighth and even–sixteenth quotes have wider quoted, effective, and realized spreads on both the NYSE and Nasdaq. This result differs from the findings by Bessembinder (1999, p. 404) that "trade execution costs on Nasdaq in late 1997 are no longer significantly explained by a tendency for liquidity providers to avoid odd–eighth quotations," and "odd–sixteenth avoidance has little relevance for explaining post–reform Nasdaq trading costs."  相似文献
