When economists report on research using mathematical models, they use a literary form similar to the experimental report in the laboratory sciences. This form consists of a narrative of a series of events, with a clear temporal segregation of the agency of the author and the agency of the ...

to perform stochastic analysis backwards in time from the value at expiration to find the call price at earlier times. Remarkably, the call price rises as the time to expiration increases, and hence, the call optionbecomes less valuable as the strikeprice increases; the BSE does satisfy this p...
The two American economists' findings have significantly broadened the scope of economic analysis by constructing models that explain how the market economy interacts with nature and knowledge, the statement added.
To all intents and purposes, this is merely an alternative prewhitening procedure that is common in time series analysis. For example, Holmes and Silverstone (2006) or Valadkhani and Smyth (2015) consider (different) regime models with distinct responses to phases of the business cycle....
of the Black–Scholes model are considered currently active fields of research. The fractional Brownian motion is not a semimartingale, and this property is crucial in modeling stock price and rough volatility, in addition to constructing hedging policies and arbitrage strategies (Black and Scholes1973...
The two American economists' findings have significantly broadened the scope of economic analysis by constructing models that explain how the market economy interacts with nature and knowledge, the statement added. "I got two phones calls this morning, didn't answer any of them, thought they were...
Economists often have limited access to the practical problems facing senior managers, while senior managers often lack the time and incentive to look beyond their own industry to the larger issues of the global economy. By integrating these perspectives, ...
This appendix provides an overview of the structure of GAMS input files which includeMPSGE models. The text of the paper presents many of these ideas by way of example, but it may also be helpful for some users to have a "template" for constructingMPSGE models. The discussion in this secti...
Bringing experts from these fields together with economists and central bankers is potentially very creative and valuable. Scientists have developed sophisticated tools for analysing complex dynamic systems in a rigorous way. These models have proved helpful in understanding many important but complex ...
