This research explores the proposition that certain disclosure and measurment practices in corporate reporting are contingent upon environmental uncertainty, technology and organisation size. The findings show that while the disclosure of forecast information is associated with environmental homogeneity, certain measurement practices are primarily influenced by company size. The results cast doubt on the general applicability of Watts and Zimmerman's (Accounting Review, January 1978, pp. 112–133) theory, and may have a number of implications for the setting of Accounting Standards. 相似文献

This article uses information on out‐of‐pocket housing cost and house price appreciation along with the geo‐coded version of the Panel Study of Income Dynamics to consider the differences in the impact of these and other variables on the tenure choices of sample households across three time periods, the 1970s, the 1980s and the 1990s. Specifically, an extended continuous time probability model is used to examine households' transitions from renting to owning and subsequent possible transitions either back to rental tenure or to another owned home during our three observation periods. Coefficient estimates show that financial variables such as house price appreciation and out‐of‐pocket housing cost play an important role in determining all the transitions. In addition, the analysis demonstrates the interesting result that the cumulative likelihoods of homeownership derived from the model are consistently lower than the probabilities of an initial transition to homeownership from rental tenure during the observation period. Finally, the magnitude and timing of the impact on homeownership of a policy experiment that eliminates the mortgage interest deduction are shown to differ substantially across the three decades. 相似文献

Retailer initiated food quality standards are important elements to market food and agricultural products. However, farmers’ certification proceeds at an unequal speed worldwide with some countries representing a large number of certified producers and others representing very few, if any. This study aims at analysing the adoption of two private food standards, BRC Food Technical Standard and GlobalGAP, at an aggregated cross-country level using data of 2007. Negative binomial models are applied to quantify the determinants of standards’ spread at an aggregated level. The results of the econometric analysis reveal some (potential) barriers for farms and firms in developing countries to access this type of organisational innovation. Certificates of both standards seem to be issued more likely in countries with established trade relations with Germany, the Netherlands and the United Kingdom, home countries of the standards. Furthermore, larger countries and countries with better institutional quality host more certified firms. Finally, a country’s level of economic development displays a clear non-monotonic relationship to the number of certified enterprises. Although no evidence for a general exclusion of developing countries can be found, the main implication of this paper is that third-party certification for export purposes seems to reinforce already existing trade relations, potentially hampering new entrants. 相似文献

In new product development (NPD), the buyer–supplier relationship is changing. Suppliers are becoming an integral part of the design team. This study investigates the effectiveness of computer-mediated and face-to-face communication channels on knowledge exchange between buyer and supplier firms, and ultimately buyer NPD and market performance. Open innovation literature and media richness theory are used to develop hypotheses which are then empirically tested using data collected from 157 R&D project managers from U.S. manufacturing firms. To date, empirical studies on the link between supplier integration and buyer performance show conflicting results. Structural equation modeling found a significant positive link between knowledge exchange and NPD performance, measured both in terms of effectiveness and efficiency, and a significant positive link between effective and efficient NPD and market performance. A surprising finding is that contrary to media richness theory, email can perform like face-to-face communication transmitting rich information and having a positive relationship to knowledge exchange between buyer and supplier. It was also found that with face-to-face communication, knowledge exchange fully mediates the relationship with effective NPD while with email communication knowledge exchange fully mediates the relationship with efficient NPD. Video conferencing was found to have no significant effect on knowledge exchange and the effect of web-based tools was significant and negative. The implications of these findings in theory and practice are discussed. 相似文献

This article presents a policy research agenda for the promotion of farm/non‐farm linkages in South Africa. Our premise is that promoting the participation of small farms and small agroindustrial businesses in these linkages will have a strong impact on employment and income for the poor. We argue that there is potential for growth in linkages. The first question of the policy research agenda concerns the current status of linkages, and we note the dearth of research on this. The second question concerns the constraints on and prospects for promoting linkages from the demand side, and the third question treats the same concerns from the supply side. The fourth question is rooted in the duality in South Africa's non‐farm and farm sectors, and asks whether, and how, small and large agroindustrial businesses and farms will compete or relate in ‘business linkages’ that can benefit intersectoral linkages. The final question concerns the impacts of and alternatives for policies and programmes to spur linkages. 相似文献

Economists and other social scientists are calling for a reassessment of the impact of international trade on labor markets
in developed and developing countries. Classical models of globalization and trade, based upon the international exchange
of finished goods, fail to capture the fragmentation of much commodity production and the geographical separation of individual
production tasks. This fragmentation, captured in the growing volume of intra-industry trade, prompts investigation of the
effects of trade within, rather than between, sectors of the economy. In this paper we examine the relationship between international
trade and the task structure of US employment. We link disaggregate US trade data from 1972 to 2006, the NBER manufacturing
database, the Decennial Census, and occupational and task data from the Dictionary of Occupational Titles. Within-industry
shifts in task characteristics are linked to import competition and technological change. Our results suggest that trade has
played a major role in the growth in relative demand for nonroutine tasks, particularly those requiring high levels of interpersonal
interaction. 相似文献

This study examines the association between tax avoidance and ex ante cost of equity capital. Based on prior research, we develop two proxies for investors’ expectations of tax avoidance and explore whether deviations from those expectations result in higher ex ante cost of equity capital. We find that the ex ante cost of equity capital increases with tax avoidance that is either below or above investor expectations and that the increase is larger for tax avoidance that exceeds investors’ expectations. We then examine whether firms that alter their future tax avoidance exhibit a lowering of their ex ante cost of equity capital and find that tax avoidance decreases (increases) from the prior year for firms that were above (below) investors’ expectations in the prior year. These results are consistent with the trade‐off suggested by the Scholes and Wolfson framework and reinforce the notion that balancing tax benefits and non‐tax costs is an important feature of firms’ tax planning. 相似文献
