Measurement errors and bounded OLS estimates

In a multiple linear regression model with one mismeasured independent variable, all coefficients are asymptotically biased. It is shown how in OLS, an examination of the sign of the cofactors of the variance-covariance matrix of measured values can be used to obtain large sample bounds on the coefficients. The method involves forward regression and regression on the mismeasured variable. Bounds are generally obtained on the coefficient of the mismeasured variable and often obtained on the remaining coefficients with no knowledge of the size of the measurement error.     

The ideology of class and tourism confronting the discourse of advertising

Starting from Baudrillard's analysis of the ideological character inherent in all consumption, touristic consumption, for many reasons ,has a special place in this social semantic. Here, advertising plays an important if not essential role because tourism is a product consumed outside of normal time and daily social space. Therefore the social semantic asserts itselfless through the product itself than through its representation: the discourse of advertising. But advertising discourse is plural, each form having its own ideology, competing with others. Behind the commercial competition lies a competition of social classes, but with a new typology, no longer based on the capital/favor relationship. Four ideological models are analyzed and illustrated with their advertising messages: the traditional model, the clerical/executive model, the youth model, and the “intellectual class” model.     

The Impact of Two-Tier Producer and Consumer Food Pricing in India

India's government buys wheat, rice, and sugar at below themarket price and then sells it in ration shops in the urbanand rural areas. The rest is sold in the open market. This createsa two-tier price system for consumers and producers. Supportersof the government's procurement policy claim that it raisesthe open-market price so much that it increases the sales-weightedaverage of the rationed price and the open-market price; inthat case, both the farm sector as a whole and low-income urbanconsumers with access to the ration shops gain, and high-incomeurban consumers who buy at the open-market price lose. Thisview has provided an intellectual basis for the policy. This article examines a variety of cases: with and without rationing;with rationing through ration cards or queuing; with and withoutaccess by the urban rich to the ration shops; with or withoutfree trade; and with a marketable surplus having either positive,negative, or zero price elasticity. The impact of the policyon the average price is in general ambiguous or negative. Underthe most plausible assumptions, it is negative, implying thatfarmers as a whole lose from the procurement policy.     

Savings and Loan Demand for Liquid Assets: Theory,Evidence and Implications for Policy*

In this study a model of liquid asset management for individual savings and loan associations is developed. The model combines features of portfolio theory and inventory theory and is used to draw hypotheses on the relationship between the demand for excess liquidity and a variety of independent variables. Pooled cross section-time series equations are estimated for the demand for excess liquidity of 198 S & Ls over the period 1974–1978. In addition to conclusions on the role of individual variables, the estimated equations reveal that the FHLBB can affect the portfolios of some, but not all, S & Ls. This implies that FHLBB liquidity policy can have an effect on the mortgage market.     

Agricultural Incentives in Developing Countries: Measuring the Effect of Sectoral and Economywide Policies

The impact of sector-specific (direct) and economywide (indirect)policies on agricultural incentives for eighteen developingcountries for the period 1975–84 are estimated. The directeffect is measured by the proportional difference between theproducer price and the border price (adjusting for distribution,storage, transport, and other marketing costs). The indirecteffect has two components. The first is the impact of the unsustainableportion of the current account deficit and of industrial protectionpolicies on the real exchange rate and thus on the price ofagricultural commodities relative to nonagricultural nontradables.The second is the impact of industrial protection policies onthe relative price of agricultural commodities to that of nonagriculturaltradable goods. We find that (1) in almost all cases the directeffect is equivalent to a tax on exportable goods (–11percent on average) and to a subsidy for importables (20 percenton average); (2) the indirect effect also taxes agriculture(–27 percent on average) and dominates the direct effect(whether the direct effect is positive or negative); and (3)the direct policies for both importables and exportables stabilizedomestic producer prices.
