Multiple Marginalization and Trade Liberalization: the Case of the Canadian Dairy Industry
MULTIPLE MARGINALIZATION AND TRADE LIBERALIZATION: THE CASE OF THE CANADIAN DAIRY INDUSTRY Abdessalem Abbassi Professeur assistant, Université de Carthage Faculté des Sciences Économiques et de Gestion de Nabeul, Bureau 160 Tel: +216 28 271 548 [email protected] Bruno Larue Canada Research Chair in International Agri‐food Trade (CREATE), Laval University [email protected] Cahier de recherche/Working paper #2012‐13 MULTIPLE MARGINALIZATION AND TRADE LIBERALIZATION: THE CASE OF THE CANADIAN DAIRY INDUSTRY Abstract: The paper analyzes the welfare impacts of trade liberalization under multiple marginalization through a spatial equilibrium model of provincial dairy markets. Canada’s dairy policy implements a supply management scheme designed to achieve higher domestic prices for farmers, taking into account the mark-up rules used by downstream firms. Our model builds on the reciprocal dumping model of Brander and Krugman (1983) as processing firms from different provinces compete à la Cournot with one another in several provinces. Simulations reveal that welfare in the Canadian dairy sector could increase by as much as $1 billion per year if aggressive tariff cuts were made while moderate liberalization plans would yield annual gains of $234.5 million. Even large producing provinces like Quebec and Ontario gain from trade liberalization. In comparison, a perfect competition model yields more modest welfare gains in the range of $15.6 million and $34.5 million. Finally, we show that the switch in the sign of the transport cost-welfare relation identified by Brander and Krugman (1983) occurs at transport costs that are too high to be policy-relevant. Résumé: Nous analysons les effets de la libéralisation des échanges sur le bien-être dans un contexte de marginalisation multiple par le biais d’un modèle spatial des marchés provinciaux pour les produits laitiers. -

Introduction to Macroeconomics Lecture Notes
Introduction to Macroeconomics Lecture Notes Robert M. Kunst March 2006 1 Macroeconomics Macroeconomics (Greek makro = ‘big’) describes and explains economic processes that concern aggregates. An aggregate is a multitude of economic subjects that share some common features. By contrast, microeconomics treats economic processes that concern individuals. Example: The decision of a firm to purchase a new office chair from com- pany X is not a macroeconomic problem. The reaction of Austrian house- holds to an increased rate of capital taxation is a macroeconomic problem. Why macroeconomics and not only microeconomics? The whole is more complex than the sum of independent parts. It is not possible to de- scribe an economy by forming models for all firms and persons and all their cross-effects. Macroeconomics investigates aggregate behavior by imposing simplifying assumptions (“assume there are many identical firms that pro- duce the same good”) but without abstracting from the essential features. These assumptions are used in order to build macroeconomic models.Typi- cally, such models have three aspects: the ‘story’, the mathematical model, and a graphical representation. Macroeconomics is ‘non-experimental’: like, e.g., history, macro- economics cannot conduct controlled scientific experiments (people would complain about such experiments, and with a good reason) and focuses on pure observation. Because historical episodes allow diverse interpretations, many conclusions of macroeconomics are not coercive. Classical motivation of macroeconomics: politicians should be ad- vised how to control the economy, such that specified targets can be met optimally. policy targets: traditionally, the ‘magical pentagon’ of good economic growth, stable prices, full employment, external equilibrium, just distribution 1 of income; according to the EMU criteria, focus on inflation (around 2%), public debt, and a balanced budget; according to Blanchard,focusonlow unemployment (around 5%), good economic growth, and inflation (0—3%). -

Amazon's Antitrust Paradox
LINA M. KHAN Amazon’s Antitrust Paradox abstract. Amazon is the titan of twenty-first century commerce. In addition to being a re- tailer, it is now a marketing platform, a delivery and logistics network, a payment service, a credit lender, an auction house, a major book publisher, a producer of television and films, a fashion designer, a hardware manufacturer, and a leading host of cloud server space. Although Amazon has clocked staggering growth, it generates meager profits, choosing to price below-cost and ex- pand widely instead. Through this strategy, the company has positioned itself at the center of e- commerce and now serves as essential infrastructure for a host of other businesses that depend upon it. Elements of the firm’s structure and conduct pose anticompetitive concerns—yet it has escaped antitrust scrutiny. This Note argues that the current framework in antitrust—specifically its pegging competi- tion to “consumer welfare,” defined as short-term price effects—is unequipped to capture the ar- chitecture of market power in the modern economy. We cannot cognize the potential harms to competition posed by Amazon’s dominance if we measure competition primarily through price and output. Specifically, current doctrine underappreciates the risk of predatory pricing and how integration across distinct business lines may prove anticompetitive. These concerns are height- ened in the context of online platforms for two reasons. First, the economics of platform markets create incentives for a company to pursue growth over profits, a strategy that investors have re- warded. Under these conditions, predatory pricing becomes highly rational—even as existing doctrine treats it as irrational and therefore implausible. -
2015: What Is Made in America?
U.S. Department of Commerce Economics and2015: Statistics What is Made Administration in America? Office of the Chief Economist 2015: What is Made in America? In October 2014, we issued a report titled “What is Made in America?” which provided several estimates of the domestic share of the value of U.S. gross output of manufactured goods in 2012. In response to numerous requests for more current estimates, we have updated the report to provide 2015 data. We have also revised the report to clarify the methodological discussion. The original report is available at: www.esa.gov/sites/default/files/whatismadeinamerica_0.pdf. More detailed industry By profiles can be found at: www.esa.gov/Reports/what-made-america. Jessica R. Nicholson Executive Summary Accurately determining how much of our economy’s total manufacturing production is American-made can be a daunting task. However, data from the Commerce Department’s Bureau of Economic Analysis (BEA) can help shed light on what percentage of the manufacturing sector’s gross output ESA Issue Brief is considered domestic. This report works through several estimates of #01-17 how to measure the domestic content of the U.S. gross output of manufactured goods, starting from the most basic estimates and working up to the more complex estimate, domestic content. Gross output is defined as the value of intermediate goods and services used in production plus the industry’s value added. The value of domestic content, or what is “made in America,” excludes from gross output the value of all foreign-sourced inputs used throughout the supply March 28, 2017 chains of U.S. -
The Declining Worker Power Hypothesis
The Declining Worker Power Hypothesis: An explanation for the recent evolution of the American economy Anna Stansbury and Lawrence H. Summers Harvard University May 2020 Abstract: Rising profitability and market valuations of US businesses, sluggish wage growth and a declining labor share of income, and reduced unemployment and inflation, have defined the macroeconomic environment of the last generation. This paper offers a unified explanation for these phenomena based on reduced worker power. Using individual, industry, and state-level data, we demonstrate that measures of reduced worker power are associated with lower wage levels, higher profit shares, and reductions in measures of the NAIRU. We argue that the declining worker power hypothesis is more compelling as an explanation for observed changes than increases in firms’ market power, both because it can simultaneously explain a falling labor share and a reduced NAIRU, and because it is more directly supported by the data.

Since the early 1980s in the U.S., the share of income going to labor has fallen, measures of corporate valuations like Tobin's Q have risen, average profitability has risen even as interest rates have declined, and measured markups have risen. -

This project would not have been possible without the organic support of my committee. I am specifically thankful to my supervisor, Elizabeth Richmond-Garza, for giving me the freedom to explore ideas at my own pace, and for reminding me to pause when my thoughts would become restless. A pause is as important as movement in the journey of a thought. I am thankful to Martha Ann Selby for suggesting me to subhead sections in the dissertation. What a world of difference subheadings make! I am grateful for all the conversations I had with Cesar Salgado in our classes on Transcolonial Joyce, Literary Theory, and beyond. I am also very thankful to Michael Johnson and Hannah Chapelle Wojciehowski for patiently listening to me in Boston and Austin over luncheons and dinners respectively. I am forever indebted to David Damrosch for continuing to read all my drafts since February 2007. I am very glad that our paths crossed in Kali’s Kolkata.
