The Substitution Problem in the Theory of Effective Protection

Input substitution theoretically invalidates the resource flow predictions of effective rates of protection calculated in a partial equilibrium framework. Partial equilibrium effective protection analysis, despite this "substitution problem," has nevertheless quietly settled into the trade economistÕs toolbox. This paper presents a new, transparent review of the substitution problem in effective protection. It finds that partial equilibrium effective protection analysis, although theoretically susceptible to misleading results, is in practice a reasonable estimator of certain short-run general equilibrium effects of protection.     

Tenure security and productivity in small‐scale agriculture in Zimbabwe: Implications for South Africa

This article tests empirically the interaction between land tenure security and agricultural productivity in small‐scale agriculture in Zimbabwe. Data for the analysis were gathered during April and August of 1995 by means of an interview survey of farmers in the small‐scale commercial sector, communal area and Model A resettlement area of Zimbabwe. Two‐stage least squares regression estimates reveal that land tenure security has a positive and significant influence on investment incentives and agricultural productivity in the sample. This result has two important implications for proposed land reforms in South .. Africa. Firstly, the result lends support to the notion that indigenous tenure institutions in communal areas of South Africa are a constraint on agricultural development. Secondly, it is clear that a national land redistribution policy must be accompanied by innovative tenure institutions which facilitate economic interaction and internalise externalities on land resettled by individuals and groups. This is particularly important in South Africa where groups of up to 300 families are being settled on commercial farms under a group ownership model.

DIVIDEND POLICY AND ITS RELATIONSHIP TO INVESTMENT AND FINANCING POLICIES: EMPIRICAL EVIDENCE

In this paper it is argued that dividend policy is not determined as a residual, but rather that firms adopt independent dividend and investment policies. Empirical evidence, based on a questionnaire survey, supports this view. Independent dividend and investment policies are possible because debt finance is usually raised in sufficient quantities to accommodate the financial demands created by dividend and investment decisions.     

Anti-Public Broadcasting

The BBC has constantly sought to justify its state support by claiming that it must offer 'public-service' broadcasting. David Graham (right), of Channel 4's Diverse Reports, argues that the BBC's position is both a misunderstanding of economic reality and a brake upon the development of consumer choice and diversity in the market. The Government's 'protection of the well-heeled' imposes 'middle-class tastes on ordinary men and women'.     

How Big Are the Tax Benefits of Debt?

I integrate under firm-specific benefit functions to estimate that the capitalized tax benefit of debt equals 9.7 percent of firm value (or as low as 4.3 percent, net of personal taxes). The typical firm could double tax benefits by issuing debt until the marginal tax benefit begins to decline. I infer how aggressively a firm uses debt by observing the shape of its tax benefit function. Paradoxically, large, liquid, profitable firms with low expected distress costs use debt conservatively. Product market factors, growth options, low asset collateral, and planning for future expenditures lead to conservative debt usage. Conservative debt policy is persistent.     

Accounting Practices and the Market Valuation of Accounting Numbers: Evidence from Indonesia, Korea, Malaysia, the Philippines, Taiwan, and Thailand

This study examines the relation between stock prices and accounting earnings and book values in six Asian countries: Indonesia, South Korea, Malaysia, the Philippines, Taiwan, and Thailand. The analysis is based on a residual earnings model that expresses the value of the firm in terms of book value and residual income. The model holds for any clean surplus accounting system. However, for finite time horizons, biased accounting may affect model estimates. The six countries examined in this study differ in faithfulness to clean surplus accounting as well as bias (conservatism). The study addresses two questions. First, are there systematic differences across countries in the value relevance of accounting, and are these differences related to accounting differences? Second, are there systematic differences in the incremental and relative information content of book value per share (BVPS) and abnormal (residual) earnings per share (REPS) across the countries, and are such differences related to accounting differences? We find differences across the six countries in the explanatory power of BVPS and REPS for firm values. Explanatory power for Taiwan and Malaysia is relatively low while that for Korea and the Philippines is relatively high. These differences are generally consistent with differences in accounting practice; however, since Korean accounting practice is strongly influenced by tax law, we did not expect the high association for Korea. Second, with respect to the incremental and relative explanatory power of BVPS and REPS, we find BVPS to have high explanatory power in the Philippines and Korea but little in Taiwan. In all six countries REPS has less explanatory power than BVPS in most years. Again, the evidence may be interpreted as suggesting accounting practice affects valuation (with Korea again as the exception). Finally, we provide evidence on the sensitivity of the timing of comparisons of stock prices and accounting values. We find that comparing prices at year-end (even though annual accounting information has not been released at that time), in general, provides the highest correlation between market and accounting numbers.     

ESTIMATION OF THE CURRENT COST OF GOODS SOLD*

In recent years current cost accounting (CCA) has received considerable attention and has resulted in the Financial Accounting Standards Board (FASB) in the USA issuing FAS33 and the Accounting Standards Committee in the UK issuing SSAP16. Similar Statements have been issued in Australia, Canada and New Zealand. The requirement to provide current cost information introduces new measurement problems. Amongst the most intractable of these is the estimation of the current cost of goods sold. The paper considers the problems associated with the techniques for estimating the current cost of goods sold which have been suggested in FAS33 and SSAP16. Alternative methods of estimating current cost of goods sold using the discipline of numerical mathematics are then reviewed. It is shown that for individual inventory lines polynomial interpolating methods provide more reliable results than those recommended in the Statements. Where a firm possesses a large numbei of inventory lines it is likely to be impracticable to apply the interpolating methods to every item of inventory. In such cases a technique referred to as STAPOL is recommended.     

The Soft Spaces of Local Economic Development

This article examines soft spaces, soft outcomes and soft infrastructure, trying to make some connections between them. We argue that soft spaces of governance constitute one of the most important but little understood components of contemporary sub-national economic development policy.
