This paper analyses the implications of cost-push shocks for the optimal choice of monetary policy target in an two-country sticky-price model. In addition to cost-push shocks, each country is subject to labour-supply and money-demand shocks. It is shown that the fully optimal coordinated policy can be supported by independent national monetary authorities following a policy of flexible inflati...

I study the effects of a lack of common knowledge on nominal adjustment in a dynamic price-setting game with incomplete information. In particular, I show how the speed of price adjustments following a nominal or real shock depends on the information structure among pricesetters. The provision of public information leads to a reduction of higher-order uncertainty, and hence to more rapid price ...

This paper addresses the nature of the demand schedule for emerging market assets in both its macroeconomic and microeconomic dimensions. The former is usually analysed in terms of the ‘push factors’ (such as interest rates or contagion) determining international capital flows; while the latter is normally approached through the portfolio composition decisions (such as herding or risk appetite)...

This paper examines the effect of the volatility of oil prices on food price in South Africa using monthly data covering the period 2002:01 to 2014:09. Food price is measured by the South African consumer price index for food while oil price is proxied by the Brent crude oil. The study employs the GARCH-in-mean VAR model, which allows the investigation of the effect of a negative and positive s...

abstract: in most industries the cost of raw materials and component parts constitutes almost 60% percent of cost of a product (in some industries up to 80%). in this situation, proper sourcing can play a key role in an organization's efficiency and effectiveness, because it has a direct effect on cost reduction, profitability and flexibility of a company. in this paper, determining the op...

B y the end of 1998, the disinflation of the 1990s had brought the U.S. price level close to absolute stability. The same disinflation witnessed a remarkable resurgence of what used to be called cost-push theories of price-level movements to explain it. Such theories, of course, attribute inflation and disinflation to a host of nonmonetary, supply-oriented influences that alter the unit cost an...

Mobile Agents are autonomous and proactive software entities which act on behalf on an owner and have the ability to migrate through a heterogeneous network of computer .A mobile agent can also decide when to migrate and which node to access. In the past few years, mobile agent (MA) paradigm has received a great deal of attention. While MAs have generated considerable excitement in the research...

We present a framework for analyzing the quality of push-grasps of extruded polygonal parts under pose uncertainty using a parallel jaw gripper. Performing a push-grasp involves using the first jaw to push the part into stable alignment, after which the second jaw closes onto the part. The motion of parts pushed on a work surface is difficult to predict if the precise interactions between the p...
