This paper presents a small macroeconometric model examining the determinants of Indian trade and inflation to address the effects of a reform policy package similar to those implemented in 1991. This is different from previous studies along one important dimension that we explicitly incorporate the non-stationarity of the data into our model and estimation procedures, which suggest that the st...

Chronic alcohol self-administration leads to alcohol-seeking behavior that is habitual and insensitive to changes in the value of the earned alcohol. Such behavior has been shown to rely on the dorsolateral region of the striatum in rats but the specific pharmacological control of output from this region is not yet understood. In the following experiments rats were trained to self-administer un...

Sign-tracking rats show heightened sensitivity to food- and drug-associated cues, which serve as strong incentives for driving reward seeking. We hypothesized that this enhanced incentive drive is accompanied by an inflexibility when incentive value changes. To examine this we tested rats in Pavlovian outcome devaluation or second-order conditioning prior to the assessment of sign-tracking tend...

Studies of animal impulsivity generally find steep subjective devaluation, or discounting, of delayed rewards - often on the order of a 50% reduction in value in a few seconds. Because such steep discounting is highly disfavored in evolutionary models of time preference, we hypothesize that discounting tasks provide a poor measure of animals' true time preferences. One prediction of this hypoth...

E xchange rate is an important factor influencing price indices of exported goods of a country in different ways. Imported intermediate commodity is one of the important ways by which the change in exchange rate affects price indices of the exported goods. Using the input-output table of Iran for the year 2001, this paper investigates the impact of exchange rate devaluation on price ...
