Price dynamics in Indian cities were examined using cointegration analysis. We identified and calculated a common trend for prices in 25 major cities in India. Impulse response functions were obtained to calculate the rates of convergence to the prices and we found that the half-life of any shock is very small for Indian cities. Although a close to three-month half-life seems too fast, there is...

This paper analyzes the role of communication between firms in an infinitely repeated Bertrand game in which firms receive an imperfect private signal of a common value i.i.d. demand shock. Communication allows firms to coordinate on the most collusive price and it eliminates the possibility of undetectable price cuts. It is shown that firms can use stochastic intertemporal market sharing as a ...

This paper analyzes the role of communication between firms in an infinitely repeated Bertrand game in which firms receive an imperfect private signal of a common value i.i.d. demand shock. It is shown that firms can use stochastic, inter-temporal market sharing as a perfect substitute for communication in low demand states. Therefore, partial communication in high demand states is sufficient t...

We analyze price adjustments in the housing market after an exogenous shock. Exploring continuous-time records of prices around a major European airport (ZRH, Switzerland), and an unexpected change in flight regulations induced by the neighboring country Germany, we find that apartment rents take about two years to stabilize to a new equilibrium value. After this period we find a constant marku...

A positive technology shock may lead to a rise or a fall in per capita hours, depending on how hours enter the empirical VAR model. We provide evidence that, independent of how hours enter the VAR, a positive technology shock leads to a weak response in nominal wage inflation, a modest decline in price inflation, and a modest rise in the real wage in the short-run and a permanent rise in the lo...

This paper characterizes the properties of various interest-rate rules in a basic forwardlooking model. We compare simple Taylor rules and rules that respond to price-level fluctuations (called Wicksellian rules). We argue that by introducing an appropriate amount of history dependence in policy, Wicksellian rules perform better than optimal Taylor rules in terms of welfare, robustness to alter...

We propose a candidate solution to the imperfect exchange rate passthrough puzzle: habit persistence at the level of individual goods varieties. Deep habits generate a dynamic import demand function that leads to import price markup adjustments, independently of nominal pricing frictions. Augmenting a standard two-country model with deep habits, we obtain low exchange rate pass-through to impor...

in this paper we examine the effect of the oil volatility, consumer price index (cpi) and industrial production on the stock market return in tehran stock exchange (tse). we used seasonal data in period 1378-1390 and auto regressive distributed method (ardl) for the short-term and long-term relationship between the variables. as results of research indicate, we find that there is positive short...

We use a statistical model to estimate impulse responses of sectoral price indices to aggregate shocks and to sector-specific shocks. In the median sector, 100 percent of the long-run response of the sectoral price index to a sector-specific shock occurs in the month of the shock. The Calvo model and the sticky-information model match this finding only under extreme assumptions concerning the p...
