doi=10.1257/jel.49.2.326 What Determines Productivity? C S * Economists have shown that large and persistent differences in productivity levels across businesses are ubiquitous. This nding has shaped research agendas in a number of elds‚ including (but not limited to) macroeconomics‚ industrial organization‚ labor‚ and trade. This paper surveys and evaluates recent empirical work addressing the question of why businesses differ in their measured productivity levels. The causes are manifold‚ and

Cost Theory in Economics A central economic concept is that getting something requires giving up something else. For example‚ earning more money may require working more hours‚ which costs more leisure time. Economists use cost theory to provide a framework for understanding how individuals and firms allocate resources in such a way that keeps costs low and benefits high. 1. Function * Economists view costs as what an individual or firm must give up to get something else. Opening a

Consumption expenditure (C) is one of four elements‚ which represents the total spending on goods and services produced in an economy. This is known as Aggregate Demand. Firstly‚ a change in real disposable income is the main factor that determines the level of consumption expenditure in an economy. Richer households and richer countries tend to spend more on goods and services in total than poorer ones due to having more money to spend. The proportion of income that is spent (average propensity

PROFIT MAXIMIZATION [See Chap 11] 1 Profit Maximization • A profit-maximizing firm chooses both its inputs and its outputs with the goal of achieving maximum economic profits 2 Model • Firm has inputs (z1‚z2). Prices (r1‚r2). – Price taker on input market. • Firm has output q=f(z1‚z2). Price p. – Price taker in output market. • Firm’s problem: – Choose output q and inputs (z1‚z2) to maximise profits. Where: π = pq - r1z1 – r2z2 3 1 One-Step Solution • Choose (z1

Q1: explicit costs and implicit costs concepts Explicit Cost Explicit cost is defined as the direct payment which is supposed to be made to others while running business. This includes the wages‚ rents or materials which are due in the contract. The explicit cost is the expense done in business which can easily be identified and accounted for in the business at any stage.

Determining the objectives of the firm is not necessarily a straightforward task because the typical firm will have many types of participants. Among these participants are shareholders‚ creditors

CHAPTER 9 OLIGOPOLY AND FIRM ARCHITECTURE 1. The demand function for a product sold by an oligopolist is given below: QD = 370 – P The firm’s marginal cost function is given below: MC = 10 + 4Q Calculate the equilibrium price and quantity. Solution: P = 370 – Q so TR = 370Q – Q2 and MR = 370 – 2Q MR = 370 – 2Q = 10 + 4Q = MC so Q = 60 and P = 310 2. The demand function for a product sold by an oligopolist is given below: QD = 135 – 0.5P The firm’s marginal cost function is given below:

economics of a profit maximizing firm Neoclassical model of the firm states that organization will have the main objective of maximizing its profit within a given period of time. Maximum profit was achieved at the output at which marginal cost is equal marginal revenue. There are several factors which need to be considered when talking about the profit maximizing firm: 1. The assumption of the profit maximizing firm is that there is no segregation between managers and owners of the firm. Owners economically

Abstract Maximizing shareholder wealth requires a decisive strategy and a well-developed plan. It allows an investor to consider financial statements and growth strategies in order to establish a course of action. Case in point‚ one major franchising international business bought a well-known global restaurant business. The risks and expected return by these two companies may affect its long-term future goals. A profitable electronics company may lose its primary supplier in a strategic takeover

1. The chief economist for Argus Corporation‚ a large appliance manufacturer‚ estimated the firm’s short-run cost function for vacuum cleaners using an average variable cost function of the form. AVC= a + bQ+ cQ^2 (the 2 is suppose to be exponent) Where AVC=dollars per vacuum cleaner and Q=number of vacuum cleaners produced each month. Total fixed cost each month is $180‚000. The following results were obtained: Dependent Variable:AVC R-Square
