A common method to study the dynamic behavior of macroeconomic variables is using linear time series models; however, they are unable to explain nonlinear behavior of the series. Given the dependency between stock market and derivatives, the behavior of the underlying asset price can be modeled using Markov switching process properties and the economic regime significance. In this paper, a two-...

Mainstream economists have long argued that the labour theory of value cannot explain price-formation. In response, Marxists mainstream economics is fixated on abstract mathematical problems which mystify social reality and obscure relationships at heart real economy. Marxist political proposed formal solutions to price-formation problem, but deeper issue my article will focus way in price sign...

Fertilizer has brought great pressure to sustainable ecological environment. Research on the effect of price fertilizer use as well substitution relationship and other input factors agricultural production is importance for green, efficient, intensive in world. This study first constructs translog cost functions models elasticity, then uses factor data from 2004 2016 measure elasticity demand, ...

The stock market has always been an attractive area for researchers since no method has been found yet to predict the stock price behavior precisely. Due to its high rate of uncertainty and volatility, it carries a higher risk than any other investment area, thus the stock price behavior is difficult to simulation. This paper presents a “data mining-based evolutionary fuzzy expert system” (DEFE...

This paper uses French food-expenditure data to examine the e¤ect of the local prices of 23 food product categories on the distribution of Body Mass Index (BMI) in a sample of French adults. A dynamic choice model using standard assumptions in Physiology is developed. It is shown that the slope of the price-BMI relationship is a¤ected by the individual’s Physical Activity Level (PAL). When the ...

I characterize time consistent equilibrium in an economy with price rigidity and an optimizing monetary authority operating under discretion. Firms have the option to increase their frequency of price change, at a cost, in response to higher inflation. Previous studies, which assume a constant degree of price rigidity across inflation regimes, find two time consistent equilibria — one with low ...
