The Role of Monetary Policy in the New Keynesian Model: Evidence from Vietnam
The role of monetary policy in the New Keynesian Model: Evidence from Vietnam By: Van Hoang Khieu William Davidson Institute Working Paper Number 1075 February 2014 The role of monetary policy in the New Keynesian Model: Evidence from Vietnam Khieu, Van Hoang Graduate Student at The National Graduate Institute for Policy Studies (GRIPS), Japan. Lecturer in Monetary Economics at Banking Academy of Vietnam. Email: [email protected] Cell phone number: +81-8094490288 Abstract This paper reproduces a version of the New Keynesian model developed by Ireland (2004) and then uses the Vietnamese data from January 1995 to December 2012 to estimate the model’s parameters. The empirical results show that before August 2000 when the Taylor rule was adopted more firmly, the monetary policy shock made considerable contributions to the fluctuations in key macroeconomic variables such as the short-term nominal interest rate, the output gap, inflation, and especially output growth. By contrast, the loose adoption of the Taylor rule in the period of post- August 2000 leads to a fact that the contributions of the monetary policy shock to the variations in such key macroeconomic variables become less substantial. Thus, one policy implication is that adopting firmly the Taylor rule could strengthen the role of the monetary policy in driving movements in the key macroeconomic variables, for instance, enhancing economic growth and stabilizing inflation. Key words: New Keynesian model, Monetary Policy, Technology Shock, Cost-Push Shock, Preference Shock. JEL classification: E12, E32. 1 1. Introduction Explaining dynamic behaviors of key macroeconomic variables has drawn a lot of interest from researchers. -

TECHNOLOGY : Production Function, Marginal Productivity of Inputs, Isoquants (1) Case of One Input: L (Labor): q = f (L) • Let q equal output so the production function relates L to q. (How much output can be produced with a given amount of labor?) • Marginal productivity of labor = MPL is defined as q = Slope of prod. Function L Small changes i.e. The change in output if we change the amount of labor used by a very small amount. • How to find total output (q) if we only have information about the MPL: “In general” q is equal to the area under the MPL curve when there is only one input. Examples: (a) Linear production functions. Possible forms: q = 10 L| MPL = 10 q = ½ L| MPL = ½ q = 4 L| MPL = 4 The production function q = 4L is graphed below. -1- Notice that if we only have diagram 2, we can calculate output for different amounts of labor as the area under MPL: If L = 2 | q = Area below MPL for L Less or equal to 2 = = in Diagram 2 8 Remark: In all the examples in (a) MPL is constant.

ERD POLICY BRIEF NO. 12 Dangers of Deflation Douglas H. Brooks and Pilipinas F. Quising December 2002 ecently, there has been growing concern about deflation in some Rcountries and the possibility of deflation at the global level. Aggregate demand, output, and employment could stagnate or decline, particularly where debt levels are already high. Standard economic policy stimuli could become less effective, while few policymakers have experience in preventing or halting deflation with alternative means. Causes and Consequences of Deflation Deflation refers to a fall in prices, leading to a negative change in the price index over a sustained period. The fall in prices can result from improvements in productivity, advances in technology, changes in the policy environment (e.g., deregulation), a drop in prices of major inputs (e.g., oil), excess capacity, or weak demand. -
Deflation: a Business Perspective
Deflation: a business perspective Prepared by the Corporate Economists Advisory Group Introduction Early in 2003, ICC's Corporate Economists Advisory Group discussed the risk of deflation in some of the world's major economies, and possible consequences for business. The fear was that historically low levels of inflation and faltering economic growth could lead to deflation - a persistent decline in the general level of prices - which in turn could trigger economic depression, with widespread company and bank failures, a collapse in world trade, mass unemployment and years of shrinking economic activity. While the risk of deflation is now remote in most countries - given the increasingly unambiguous signs of global economic recovery - its potential costs are very high and would directly affect companies. This issues paper was developed to help companies better understand the phenomenon of deflation, and to give them practical guidance on possible measures to take if and when the threat of deflation turns into reality on a future occasion. What is deflation? Deflation is defined as a sustained fall in an aggregate measure of prices (such as the consumer price index). By this definition, changes in prices in one economic sector or falling prices over short periods (e.g., one or two quarters) do not qualify as deflation. Dec lining prices can be driven by an increase in supply due to technological innovation and rapid productivity gains. These supply-induced shocks are usually not problematic and can even be accompanied by robust growth, as experienced by China. A fall in prices led by a drop in demand - due to a severe economic cycle, tight economic policies or a demand-side shock - or by persistent excess capacity can be much more harmful, and is more likely to lead to persistent deflation. -
Economics 352: Intermediate Microeconomics
EC 352: Intermediate Microeconomics, Lecture 7 Economics 352: Intermediate Microeconomics Notes and Sample Questions Chapter 7: Production Functions This chapter will introduce the idea of a production function. A production process uses inputs such as labor, energy, raw materials and capital to produce one (or more) outputs, which may be computer software, steel, massages or anything else that can be sold. A production function is a mathematical relationship between the quantities of inputs used and the maximum quantity of output that can be produced with those quantities of inputs. For example, if the inputs are labor and capital (l and k, respectively), the maximum quantity of output that may be produced is given by: q = f(k, l) Marginal physical product The marginal physical product of a production function is the increase in output resulting from a small increase in one of the inputs, holding other inputs constant. In terms of the math, this is the partial derivative of the production function with respect to that particular input. The marginal product of capital and the marginal product of labor are: ∂q MP = = f k ∂k k ∂q MP = = f l ∂l l The usual assumption is that marginal (physical) product of an input decreases as the quantity of that input increases. This characteristic is called diminishing marginal product. For example, given a certain amount of machinery in a factory, more and more labor may be added, but as more labor is added, at some point the marginal product of labor, or the extra output gained from adding one more worker, will begin to decline. -

The End of Modern Economic Growth as We Know It by Jean-Pierre Dormois Economic progress is behind us in the West, warns Robert J. Gordon in a 750 pages-tome which revisits the economic history of the U.S. in the last century and a half. Measuring the impact on living standards of the major technological breakthroughs of the “second industrial revolution,” he observes that sources of productivity growth seem to have dried since the 1970s oil shock and that the productivity-enhancing effects of the digital “revolution” have so far proved elusive.

Growth Accounting Karl Whelan School of Economics, UCD Spring 2020 Karl Whelan (UCD) Growth Accounting Spring 2020 1 / 20 Growth Accounting The final part of this course will focus on \growth theory." This branch of macroeconomics concerns itself with what happens over long periods of time. We will look at the following topics: 1 What determines the growth rate of the economy over the long run and what can policy measures do to affect it? 2 What makes some countries rich and others poor? 3 How economies behaved prior to the modern era of economic growth. 4 The tensions between economic growth and environmental sustainability. We will begin by covering \growth accounting" { a technique for explaining the factors that determine growth. Karl Whelan (UCD) Growth Accounting Spring 2020 2 / 20 Production Functions We assume output is determined by an aggregate production function technology depending on the total amount of labour and capital. For example, consider the Cobb-Douglas production function: α β Yt = At Kt Lt where Kt is capital input and Lt is labour input. An increase in At results in higher output without having to raise inputs. Macroeconomists usually call increases in At \technological progress" and often refer to this as the \technology" term. At is simply a measure of productive efficiency and it may go up or down for all sorts of reasons, e.g. with the imposition or elimination of government regulations. Because an increase in At increases the productiveness of the other factors, it is also sometimes known as Total Factor Productivity (TFP). -

Cities, Information, and Economic Growth
Cities, Information, and Economic Growth Cities, Information, and Economic Growth Edward L. Glaeser Harvard University Great are the advantages which people following the same skilled trade get from near neighborhood to one another. The mysteries of the trade become no mysteries; but are, as it were, in the air. A. Marshall Principles of Economics For centuries economists have fervently sought to understand the forces behind economic progress. Smith (1776), Marx (1909), Marshall (1890), Young (1928), and Keynes (1936) all hotly pursued this topic. In the post-World War II period, economic theorists, develop- ment economists, macroeconomists, econometricians, economic historians, and growth economists have devoted considerable energy to thinking about the forces behind long- run growth rates. It would be impossible to claim that these economists have reached a consensus on the causes of growth, but it seems clear that the growth of economies does not involve the simple accumulation of capital and labor. Theoretical models of capital accumulation (based on Solow, 1956, for example) ultimately leave the growth rate as an unexplained outside parameter. Empirically the stunning range of cross-national experiences makes it clear that the forces driving growth are rich and varied. Instead of continuing to use simple capital accumulation models, economists (following Romer, 1986) have moved toward models in which the stock of knowledge, in the Nation and the world, plays a critical role in facilitating progress. The nature of intellectual capi- tal—mostly the presence of strong external effects—solves certain technical problems when explaining why global increasing returns, which are necessary to explain growth, can coexist with competition. -

The General Theory of Employment, Interest, and Money. Keynes, John
Intermediate Macroeconomic Analysis ECON 302 SUMMER 2013 DREW UNIVERSITY (Preliminary Syllabus) Jamee K. Moudud [email protected] Office: TBA Office Hours: TBA Course Description This course is a study of the determinants of the level of income, employment, and prices as seen in competing theoretical frameworks. Topics include an analysis of inflation and unemployment, their causes, costs, and policy options; the sources of instability in a market economy; debates on policy activism; prospects for the control of aggregate demand. The objective of the course is to enable students to learn the fundamental theoretical debates in economics and their real-world implications. At every step we will contrast the neoclassical approach with alternative approaches, including that of Keynes who is generally considered to be the founder of modern macroeconomics. We will therefore draw on both a macroeconomics textbook and Keynes’ famous book The General Theory of Employment, Interest, and Money. Textbooks: Peterson, Wallace C. and Estenson, Paul S. (1996).
