This paper explores the effects of government consumption spending in a small open economy both under flexible and fixed exchange rate regimes. Varying price elasticity and the variety effect due to firm entry, are introduced to match the empirical evidences on the small open economy. The main mechanism is that firm entry leads to a higher price elasticity (hence variable markup), and increasin...

Concentric hypertrophy is characterized by ventricular wall thickening, fibrosis, and decreased myocyte length-to-width aspect ratio. Ventricular thickening is considered compensatory because it reduces wall stress, but the functional consequences of cell shape remodeling in this pathological setting are unknown. We hypothesized that decreases in myocyte aspect ratio allow myocytes to maximize ...

Background: Imposing taxes on tobacco has been identified as one of the most effective methods of reducing tobacco use. Vietnam's tax structure, which sets different rates based on type of cigarette, has implications for the level of cigarette prices, economic burden of smoking, effect on tobacco use, and effect on tax revenues. Methods: Using data from the large scale Vietnam Living Standard S...

Marketing literature has long recognized that price response need not be monotonic and symmetric, but has yet to provide generalizable market-level insights on reference price type, asymmetric thresholds and sign and magnitude of elasticity transitions. In this paper, we introduce smooth transition models to study reference-based price response across 25 fast moving consumer good categories. Ou...

This study exploits a natural experiment in Belgium to estimate the effect of copayment increases on the demand for physician services. It shows how a differences-in-differences (DD) estimator of the price effects can be decomposed into effects induced by the common average proportional price increase (income effects) and by the change in relative prices (substitution effects). The price elasti...

Iran has experienced high food prices in recent years. This paper examines the welfare impacts of rising major food groups' prices on Iranian urban households using Quadratic Almost Ideal Demand System (QUAIDS) approach. The elasticity coefficients derived from QUAIDS are used to estimate Compensated Variations (CV).The study uses Iranian Household Expenditure and Income Survey (HEIS) raw data,...

Among the agricultural important factors, inputs are the most significant in agricultural production. This article aimed to examine the impact of government subsidy policies on production of one of the most strategic products, namely on production of one of the most strategic products, namely maize, in Iran. To achieve this goal, panel data for the nine provinces of Iran's major producers of ma...

agricultural activities are risky activities. in these activities, various natural, social and economic risks have created fragile and vulnerable situation for producers. price risk in agricultural products has caused financial problems for many producers and farmers. to deal with these price risks and price fluctuations, there are varieties of tools. this paper focused on futures markets instr...

the main purpose of this study is to determine welfare impacts of trade liberalization on maize market. for this purpose, we used from time series data for the period 1961/2009 and estimated domestic supply, domestic demand and import demand for maize. results of estimation showed that price elasticity of supply and demand is 0.32 and -0.25, respectively. then, by means of these elasticities, w...

In this paper, impacts of day-ahead market pricing on behavior of producers and consumers in option and day-ahead markets and on option pricing are studied. To this end, two comprehensive equilibrium models for joint put option and day-ahead markets under pay-as-bid and uniform pricing in day-ahead market are presented, respectively. Interaction between put option and day-ahead markets, uncerta...
