Agricultural Comparative Advantage and Government Policy Interventions

International trade patterns are often explained by comparative advantage which is frequently thought to depend on variations in national factor endowments. Government intervention in agricultural markets may also have an impact on trade patterns. This study explores the relation between factor endowments and agricultural trade patterns and examines the impact of agricultural and environmental policies on trade flows. Measures of national endowments of capital, labour, land and energy reserves are computed for a sample of 40 countries and used to estimate Heckscher‐Ohlin‐Vanek equations with net trade in several agricultural commodities as the dependant variable. Variables measuring agricultural policy and environmental regulations are added to the equations and tested for significance. The variables representing government intervention do not contribute to the explanation of trade patterns while national factor endowments do account for much of the variation in trade patterns of grains, oilseeds, cotton, and, to a lesser extent, meat products and an aggregate of all agricultural goods. Commodities such as sugar, tropical products and fruits and vegetables do not appear to be well explained by factor endowments.     

Some considerations on a class of macro-economic production functions

Summary It is demonstrated that dimensional analysis can be a tool in investigating the properties of a production function. First, the economic implications of the CES Function are shown. Secondly, endorsing the statements made by the SMAC Group that the Leontief and the Cobb and Douglas types of the production function arise as limiting cases of the CES production function, detailed proofs of these statements are given that maintain the dimensional homogeneity in proceeding to the limits. It is shown that certain dimensional constants of the CES production function become dimensionless entities in the limit.Finally, an expression for the curvature of the isoquants is derived. A dimensionally homogeneous relation is presented between the elasticity of substitution, the slope, the curvature and the factor endowments. This relation can be used to derive a general Variable Elasticity of Substitution production function.1970-71 Visiting Professor, Department of Economics, F.S.U.

ARE COMMON STOCKS A HEDGE AGAINST INFLATION?

We test whether U.K. common stocks hedge against inflation using a framework of the tax‐augmented Fisher hypothesis. Aggregate and disaggregate (seven industry groups) monthly data covering 48 years are used. All pairs of stock and retail price indexes are cointegrated. Tests in most cases reveal significant shifts in the cointegrating vectors, and accounting for these shifts improves the precision of the estimates. The point estimates of goods price elasticity are significantly above unity in all but two cases. These findings, though in sharp contrast to most existing findings that report price elasticity of below unity, appear theoretically more plausible because nominal stock returns must exceed the inflation rate to insulate tax‐paying investors.     

Globalization and growth in the low income African countries with the extreme bounds analysis

The relationship between globalization and economic growth, especially in the poorer developing countries, is controversial. Previous studies have used single globalization indicators such as the ratio of exports plus imports to GDP. This paper uses a comprehensive measure of a globalization of Dreher (2006), which is based on measures of globalization of the economic, social and political sectors. Panel data estimates with data of 21 low income African countries show a small but significant positive permanent growth effects. The sensitivity of this growth effect is examined with the extreme bounds analysis (EBA). Contrary to the findings by Levine and Renelt (1992) that cross-country growth relationships are fragile, the effects of globalization and some other determinants of the long run growth rate are found to be robust by EBA.     

Government Production Technologies in Canada: 1961 to 2000

This study explores the long-term trends of government production technologies in Canada for the past four decades, i.e. from 1961 to 2000, using the annual Canadian input-output data. According to the industry technology concept of input-output analysis, each industry chooses its human and material resource requirements and uses them as inputs in its production processes. The shares of inputs to the total spending depict the technologies employed by the corresponding industries. As such, the long-term shifts in the input shares reveal the trends of industry production technologies for a given period. This study draws on this concept to explore the long-term trends of government production technologies. It also discusses the underlying reasons for the observed trends. Among other things, the study shows that the government production technologies in Canada were influenced not only by the changing functional patterns, but also by the changing input patterns of government expenditure. In addition, the combined shares of employee compensation and capital consumption, both own-account resources, steadily declined. On the other hand, the combined shares of purchased services and other inputs, which are resources acquired from outside sources, gradually rose during the past four decades.     

Theoretical Implications of Imperfect Competition on Quota License Prices and Auctions

This article looks at the implications for trade policy of recentwork on quota auctions. Recent work has considered a varietyof market structures in addition to the standard one of monopolyin the product market. It has also emphasized details of theimplementation process, as well as the timing of decisions anddynamic factors. Such considerations are shown to be important,because they can greatly affect the outcome of trade policies.     

The determinants of recovery from the Black Saturday bushfire: demographic factors,behavioural characteristics and financial literacy

We investigate the contribution of demographic factors, behavioural characteristics and financial literacy to recovery from the financial losses inflicted by the Black Saturday bushfire. Behavioural characteristics (such as overconfidence, self-serving and loss aversion biases) in conjunction with bushfire survivors’ knowledge of financial indicators are used to determine recovery time. Data are collected through in-depth interviews with bushfire survivors, academics and experts in natural disasters. The results show that demographic, behavioural and financial literacy factors have the potential to enhance the recovery process.
