Dynamics of Wheat Prices in the Wake of Market Reforms: The Case of Pakistan

Using Autoregressive Conditional Heteroskedastic (ARCH) method, this paper examines the effects of market reforms on the distribution of real mean prices and their variability before and after reforms. It is found that market-oriented reforms benefited producers and consumers alike. Empirical evidences, generally, support theoretical assertion that mean prices decline in most urban areas and increase in those markets that are located in surplus producing areas. The results also showed that market reforms lead to more price volatility.     

Local measured telephone service in the USA: A quantitative analysis

The USA has steadfastly held to a flat rate for local telephone service, whereas most other countries are characterized by a user-sensitive (measured service) system of pricing. Economic theory suggests some method of measured service pricing more accurately reflects the true costs of local service. This article seeks to determine how many US consumers could be induced to switch to measured service pricing, and using ordinary least squares, derives a model of the demand for measured service. The factors are identified that will induce the US population to move towards a measured service rate structure. The findings indicate that consumers are quite responsive to both relative price (between a local flat rate and a measured service rate) and advertising.

On the selection of forecasting models

It is standard in applied work to select forecasting models by ranking candidate models by their prediction mean squared error (PMSE) in simulated out-of-sample (SOOS) forecasts. Alternatively, forecast models may be selected using information criteria (IC). We compare the asymptotic and finite-sample properties of these methods in terms of their ability to mimimize the true out-of-sample PMSE, allowing for possible misspecification of the forecast models under consideration. We show that under suitable conditions the IC method will be consistent for the best approximating model among the candidate models. In contrast, under standard assumptions the SOOS method, whether based on recursive or rolling regressions, will select overparameterized models with positive probability, resulting in excessive finite-sample PMSEs.
