This paper addresses the problem of identifying incompatibilities between two programs that operate in a producer/consumer relationship. It describes the techniques that are incorporated in a tool called PCCA (Producer-Consumer Conformance Analyzer), which attempts to (i) determine whether the consumer is prepared to accept all messages that the producer can emit, or (ii) find a counterexample:...

the purpose of this paper is to estimate the welfare cost of inflation in iran. we first use the long-horizon regression approach developed by fisher and seater (1993) to obtain an estimate of the inflation rate elasticity of money demand and then the baily’s consumer surplus approach to calculate the welfare cost function. the results show that reducing inflation rate from 40% to 0% increases ...

This paper analyzes the welfare effects of monopoly differential pricing in the important but largely neglected case where costs of service differ across consumer groups. Cost-based differential pricing is shown to increase total welfare and consumer welfare relative to uniform pricing for broad classes of demand functions, even though total output can still fall or the output allocation betwee...

We estimate the welfare associated with the Medicare HMO program, now known as Medicare+Choice (M+C). We find that the creation of the M+C program resulted in approximately $15.6 billion in consumer surplus and $52 billion in profits from 1993 to 2000 (in 2000 dollars). This program most likely generated significant net social welfare. However, we find that consumer surplus is geographically un...

Other consumers, however, still purchase large packages and overconsume. From a strategic perspective, firms have the option of introducing small pack...

Welfare effect of tariff for a small country in the case of traditional tariff (exogenous) compared to free trade would decrease the welfare of the country. This paper has shown that the welfare effect of tariff in case of untraditional tariff (endogenous) can be explained by using the specific factors models (Jones) that fundamentally determined by Cournut- Nash Equilibrium system in contrary ...
