Geographic earnings disclosure and trading volume

Beginning with Statement of Financial Accounting Standards No. 131 (SFAS 131), Disclosures about Segments of an Enterprise and Related Information, most US multinational firms no longer disclose geographic earnings in their annual reports. Given the recent growth in foreign operations of US firms and the varying operating environments around the world, information (or lack thereof) related to geographical performance can affect investors’ information set. Using empirical tests that closely follow the [Kim, O., Verrecchia, R., 1997. Pre-announcement and event-period private information. Journal of Accounting and Economics 24, 395–419] model, we find results consistent with their predictions. Specifically, using a sample of firms with substantial foreign operations, we find evidence of a decrease in event period private information following adoption of SFAS 131 for firms that no longer disclose geographic earnings. These results suggest that decreased public information (i.e., non-disclosure of geographic earnings) reduces the ability of investors to utilize or generate private information in conjunction with the public announcement of quarterly earnings, which dampens trading. We also find evidence of a decrease in pre-announcement private information following adoption of SFAS 131. This is consistent with an overall improvement in public disclosures that has the effect of reducing differences in the precision of private information across investors in the period prior to the earnings announcement. However, such an effect is observed for both firms which no longer disclose geographic earnings and for firms that continue to disclose geographic earnings.     

Segment Disclosure and Cost of Capital

We investigate whether segment disclosure influences cost of capital. Improved segment reporting is expected to decrease cost of capital by reducing estimation risk. However, in a competitive environment segment disclosure may also generate uncertainties about future prospects and lead to a larger cost of capital. Asset‐pricing tests confirm that segment disclosure is a priced risk factor. Also, segment disclosure reduces ex‐ante estimates of cost of equity capital and other measures connected to risk. These results suggest a negative relation between segment disclosure and cost of capital. Our results also show that competition reduces, but does not eliminate, the previous relationship.     

From Consolidation to Segment Reporting in Local Government： Accountability Needs,Accounting Standards,and the Effect on Decision-Makers

Consolidated Financial Statements （CFSs） in the public sector represent useful financial tools to improve transparency and accountability toward internal and external users. This aggregate view is only a part of the information needed in order to give politicians, managers, employees, financial institutions, rating agencies, and citizens a whole view of a local government＇s financial performance. It emerges the need to have segment information, covering specific policy areas for which it is appropriate to separately report financial and non-financial information. This paper, after having discussed the need for accountability and decision-making in a theoretical framework, gives account of a pilot project realized by the municipality of Reggio Emilia, which introduced CFSs and segment reporting. The empirical study is based on an action research as a methodological approach to solving practical problems. Finally, the paper also offers some practical suggestions to contribute to the applicability of the segment reporting in the public sector.     

Demographic Dividends in the ‘South’, Ageing ‘North’, and ‘South-South’ Trade Diversification

The absence of clear convergence in incomes per capita and welfare between the North and the South, even in the face of spectacular growth rates in GDP in the emerging South, might be due to a terms of trade deterioration resulting from an expansion of production in the South which depresses the product’s price on world markets. This may originate from a “technical catch up” and also from a “demographic dividend” in the South relative to an ageing North. This article illustrates that some South-South trade diversification might mitigate the terms of trade deterioration and increase welfare gains in the South. We use a multicountry overlapping-generation general equilibrium model to simulate the magnitude of the terms of trade effect due to a demographic dividend in Turkey, and show that some trade diversification away from EU toward the South is a welfare improving policy for Turkey.     

MAXIMUM SUSTAINABLE GOVERNMENT DEBT IN THE PERPETUAL YOUTH MODEL

The overlapping‐generations model of Blanchard, based on a constant probability of death, is used to study the maximum level of government debt consistent with the existence of a steady state equilibrium. In both a small open and a closed economy it is shown that maximum sustainable debt robustly occurs where the consumption of individual households reaches zero, the limit of its feasible range. Taxation absorbs all of the household's labour income here. In a closed economy, at this point the real interest rate also hits a ‘ceiling’ given by a simple combination of preference parameters and the death probability.     

Accounting for the Changing Role of Family Income in Determining College Entry

In this paper, I analyze the determinants of college enrolment and the changes in these determinants over time. I propose a quantitative life‐cycle model with college enrolment. Altruistic parents provide financial support to their children. Using counterfactual experiments, I find that 24 percent of all households are financially constrained in their college decision. Constraints become more severe over time. I show that my model is consistent with a narrow college enrolment gap between students from rich and poor families, as previously reported in the empirical literature. The estimation of enrolment gaps is a popular reduced‐form approach for measuring the fraction of constrained households. My results suggest that these reduced‐form estimates are misleading, and that a structural model of parental transfers is needed to correctly identify constrained households. Further, I show that parental transfers are an important driver behind the changing role of family income as a determinant of college entry, a fact that is well documented for the US economy.

Social inequalities in injury risk in Wales,U.K.

Road traffic accident data in Nigeria generally lack exact coordinate information. Accident analysis is, therefore, restricted to aggregate data on trends, magnitude and temporal dimensions. This article addresses the road accident problem in Jos between 1995 and 1999 through a road profiling approach. Results show that four gateway routes, seven multilane roadways (including two gateway routes) and seven road intersections accounted for 84% of all traffic accidents, 84% of injured casualties and 88% of fatalities. This approach allows for quantification of impacts of controlling for accidents by deliberate profiling of roads for close monitoring and policing. For example, reducing accident counts and fatalities by 50% each on gateway routes will amount to ～35 and 40% reduction in accident and fatality counts, respectively. Countermeasures must consider these roadways and intersections as important inputs in their accidents and casualty reduction targets.     

Welfare Effects of Capital Taxation in a Small Open Economy

In a small open economy, the welfare effect of capital taxation depends on the allocation of the tax revenue as well as the tax system. If tax revenues are used to finance debt or government spending, an increase in either residential or territorial capital taxation will reduce the welfare of the representative individual. If tax revenues are transferred intergenerationally, an increase in the residential capital tax rate will increase the steady-state welfare when the after-tax interest rate is greater than the growth rate. If the revenue is rebated to the tax payer, an introduction of territorial capital taxation may increase welfare when the growth rate is relatively high. In the case where either the revenue from residential capital taxation is rebated to the tax payer or the revenue from territorial capital taxation is transferred intergenerationally, the welfare-maximizing tax rate appears to be zero.
