Producer Theory

چکیده
Since Marshall, the standard approach to developing a theory of competitive markets is to separate demand behavior (“consumer theory”) from supply behavior (“producer theory”) and then use the notion of market equilibrium to reconcile demand and supply. This note studies producer theory and a separate one studies consumer theory. The standard model has the following features. Firms are described by fixed and exogenously given technologies that allow them to convert inputs (in simple models, these are land, labor, capital and raw materials) into outputs (products). “Competitive” producers take both input and output prices as given, and choose a production plan (a technologically feasible set of inputs and outputs) to maximize profits. Before we get into the details, let’s remark on a few key features of the model.

Producer cooperatives: a Transaction Cost Economic Approach
This paper aims at positioning producer cooperatives within the Transaction Cost Economics theory, one of the most cited and prolific theories on management studies. To accomplish this goal, I will answer the questions what is a cooperative, which transactions producer cooperatives regulate, under which market conditions they operate, and where are the boundaries for such organizations. This pa...
متن کاملA Linear/Producer/Consumer Model of Classical Linear Logic
This paper defines a new proofand category-theoretic framework for classical linear logic that separates reasoning into one linear regime and two persistent regimes corresponding to ! and ?. The resulting linear/producer/consumer (LPC) logic puts the three classes of propositions on the same semantic footing, following Benton’s linear/non-linear formulation of intuitionistic linear logic. Seman...
متن کاملEfficiency and surplus bounds in Cournot competition
We derive bounds on the ratios of deadweight loss and consumer surplus to producer surplus under Cournot competition. To do so, we introduce a parameterization of the degree of curvature of market demand using the parallel concepts of ρ-concavity and ρ-convexity. The more concave is demand, the larger the share of producer surplus in overall surplus, the smaller is consumer surplus relative t...
متن کاملExplaining the Wage Gap: Heckscher-Ohlin, Economic Geography and Services Availability1
In the debate on globalisation and wage inequality HeckscherOhlin theory has featured prominently. However, a neglected mechanism by which globalisation affects labour market outcomes is through the increased tradability of producer services. By integrating elements of Heckscher-Ohlin theory, the economic geography literature and the literature on producer services linkages, we show that the im...
متن کاملDo Producer Prices Cause Consumer Prices? Some Empirical Evidence
The main purpose of this paper is to examine the relationship between consumer price index (CPI) and producer price index (PPI) in Malaysia. This research considers monthly data of consumer price index and producer price index from January 1986 to April 2007. The Johansen cointegration method suggests that there is long-run equilibrium relationship between these two variables. Both Engle Grange...
