Price Stickiness in US-Corn Market: Evidence from Dsge-Var Simulation

This study examines price stickiness in the United States (US) corn market using annual series data, on the dollar price of corn per bushel, obtained from the United States Department of Agriculture (USDA) and Federal Reserve Bank of Saint Louis (FRED), between 1930 and 2017. The study implemented the Calvo price stick model based on an agent in a general equilibrium and New Keynesian type, simulated using DSGE-VAR. The approach permits the indexing formula to include expected corn inflation rather than lagged inflation. The results show that corn price inflation only persists by 2% every trading year, resulting from changes in the immediate future corn-price inflation and output-gap, respectively. The shock to stochastic term only causes a partial decline in the corn price, converging at a future date with its long-run equilibrium. The experiment confirmed that corn price fluctuations are beyond the purview of the domestic economy, and any attempt to impose price policies will offset the price setting, creating further distortions and a wider gap in the corn yield. The study provides fresh insight into the Calvo price stick model of the New Keynesian type and its use to forecast agricultural outcomes.

A Dynamic Oligopoly with Price Stickiness and Risk-Averse Agents

In this paper we present a dynamic discrete-time model that allows to investigate the impact of risk-aversion in an oligopoly characterized by a homogeneous non-storable good, sticky prices and uncertainty. The continuous-time limit of our formulation nests the classical dynamic oligopoly model with sticky prices by Fershtman and Kamien (Econometrica 55:1151–1164, 1987) and extends it by accommodating uncertainty and risk-aversion. We show that in the continuous-time limit of our infinite horizon formulation the optimal production strategy and the consequent equilibrium price are, respectively, directly and inversely related to the degrees of uncertainty and risk-aversion. However, the effect of uncertainty and risk-aversion crucially depends on price stickiness since, when prices can adjust instantaneously, the steady state equilibrium in our model with uncertainty and risk-aversion collapses to Fershtman and Kamien’s analogue.

Determinants of Price Rigidity and Flexibility: Some Survey Evidence for the Pakistan.

The objective of the study is to estimate the determinants of price stickiness or flexibility. Data is collected through structured questionnaire from 342 firms, which are selected through stratified random sampling technique from the Industrial Estate of Khyber Pakhtunkhwa. To estimate the determinants of price flexibility/rigidity, models are estimated through ordinary least squares technique and binary logistic technique. The most important factors for price stickiness are implicit/explicit price contracts and minimum price volatility. Imperfect competitive market structure, number of regular customers, backward-looking behavior, and credibility of central bank and size of the firm are important determinants of price rigidity. While economic literacy and information set regarding expected inflation make the prices flexible. Study recommend that monetary policy of Pakistan should use other transmission channels of money supply instead of traditional channel, because it is found that the degree of price rigidity is low in Pakistan. Keywords: Price Rigidity, Price Flexibility, Price Contract, Frequency of Price Change.

The golden rule of public finance under active monetary stance: endogenous setting for a developing economy

The paper aims to verify the introduction of the golden rule of public finance under an active monetary stance for a developing economy using a dynamic stochastic general equilibrium model. Besides the two rigidities, namely the deep habit formation and Calvo-style price stickiness, the model structure incorporates real money holdings and welfare-enhancing government purchases in the utility-generating function and a modified Taylor rule. The simulation results have validated the visible crowding-out of private consumption and investment in the short run and a positive impact of the productive government spending on long-run growth, but with some important caveats. In the case of a developing economy that usually has low efficiency and high returns to public capital, the given factors prove significant in addressing the study issue. The results are robust in terms of the structure of utility-generating function, a relatively high share of liquidity-constrained households, and a degree of price stickiness. Moreover, to offset the debt accumulation as a result of increased public investment financing by persistent output growth, in the long run, the central bank should not only rely on response to the fluctuation of inflation and output but also account for a move of public debt.

Optimal inflation, monetary integration, and asymmetric sticky prices

This article explores the optimal rate of trend inflation in open economies with and without a monetary union, accounting for empirically observed differences in the degree of price stickiness across countries. In a closed economy, the optimal inflation rate is negative to offset the markup caused by imperfect competition. In an open economy there is a ‘beggar-thy-neighbour’ incentive and the optimal inflation is positive. Monetary union is globally welfare improving because it removes this externality. In both setups, as price stickiness increases, the degree of price dispersion increases, and the optimal inflation rate tends towards zero. Gains from monetary integration are higher for economies with more flexible prices.

The Cross-Sectional Distribution of Price Stickiness Implied by Aggregate Data

We provide evidence on three mechanisms that can reconcile frequent individual price changes with sluggish aggregate price dynamics. To that end, we estimate a semistructural model that can extract information about real rigidities and the distribution of price stickiness from aggregate data. Hence, the model can also speak to the debate about the aggregate implications of sales. Our estimates indicate large real rigidities and substantial heterogeneity in price stickiness. Moreover, the cross-sectional distribution of price stickiness implied by aggregate data is in line with an empirical distribution obtained from microprice data that factors out sales and product substitutions.
