Book Description
Reality-based modeling for today's unique economic recovery Economic Modeling in the Post Great Recession Era presents a more realistic approach to modeling, using direct statistical applications to address the characteristics and trends central to current market behaviors. This book's unique focus on the reality of today's markets makes it an invaluable resource for students and practitioners seeking a comprehensive guide to more accurate forecasting. While most books treat the economy as if it were in a vacuum, building models around idealized or perception-biased behaviors, this book deals with the economy as it currently stands—in a state of recovery, limited by financial constraints, imperfect information, and lags and disparities in price movements. The authors identify how these characteristics impact various markets' behaviors, and quantify those behaviors using SAS as the primary statistical tool. Today's economy bears a number of unique attributes that usual modeling methods fail to consider. This book describes how to approach modeling based on real-world, observable data in order to make better-informed decisions in today's markets. Discover the three economic characteristics with the greatest impact on various markets Create economic models that mirror the current post-recession reality Adopt statistical methods that identify and adapt to structural breaks and lags Factor real-world imperfections into modeling for more accurate forecasting The past few years have shown a clear demarcation between policymakers' forecasts and actual outcomes. As the dust settles on the Great Recession, after-effects linger—and impact our current recovery in ways that diverge from past experience and theoretical expectations. Economic Modeling in the Post Great Recession Era provides comprehensive guidance grounded in reality for today's economic decision-makers.

The Great Recession
Author: David B. Grusky
Publisher: Russell Sage Foundation
ISBN: 1610447506
Category : Business & Economics
Languages : en
Pages : 342
Book Description
Officially over in 2009, the Great Recession is now generally acknowledged to be the most devastating global economic crisis since the Great Depression. As a result of the crisis, the United States lost more than 7.5 million jobs, and the unemployment rate doubled—peaking at more than 10 percent. The collapse of the housing market and subsequent equity market fluctuations delivered a one-two punch that destroyed trillions of dollars in personal wealth and made many Americans far less financially secure. Still reeling from these early shocks, the U.S. economy will undoubtedly take years to recover. Less clear, however, are the social effects of such economic hardship on a U.S. population accustomed to long periods of prosperity. How are Americans responding to these hard times? The Great Recession is the first authoritative assessment of how the aftershocks of the recession are affecting individuals and families, jobs, earnings and poverty, political and social attitudes, lifestyle and consumption practices, and charitable giving. Focused on individual-level effects rather than institutional causes, The Great Recession turns to leading experts to examine whether the economic aftermath caused by the recession is transforming how Americans live their lives, what they believe in, and the institutions they rely on. Contributors Michael Hout, Asaf Levanon, and Erin Cumberworth show how job loss during the recession—the worst since the 1980s—hit less-educated workers, men, immigrants, and factory and construction workers the hardest. Millions of lost industrial jobs are likely never to be recovered and where new jobs are appearing, they tend to be either high-skill positions or low-wage employment—offering few opportunities for the middle-class. Edward Wolff, Lindsay Owens, and Esra Burak examine the effects of the recession on housing and wealth for the very poor and the very rich. They find that while the richest Americans experienced the greatest absolute wealth loss, their resources enabled them to weather the crisis better than the young families, African Americans, and the middle class, who experienced the most disproportionate loss—including mortgage delinquencies, home foreclosures, and personal bankruptcies. Lane Kenworthy and Lindsay Owens ask whether this recession is producing enduring shifts in public opinion akin to those that followed the Great Depression. Surprisingly, they find no evidence of recession-induced attitude changes toward corporations, the government, perceptions of social justice, or policies aimed at aiding the poor. Similarly, Philip Morgan, Erin Cumberworth, and Christopher Wimer find no major recession effects on marriage, divorce, or cohabitation rates. They do find a decline in fertility rates, as well as increasing numbers of adult children returning home to the family nest—evidence that suggests deep pessimism about recovery. This protracted slump—marked by steep unemployment, profound destruction of wealth, and sluggish consumer activity—will likely continue for years to come, and more pronounced effects may surface down the road. The contributors note that, to date, this crisis has not yet generated broad shifts in lifestyle and attitudes. But by clarifying how the recession’s early impacts have—and have not—influenced our current economic and social landscape, The Great Recession establishes an important benchmark against which to measure future change.

The Great Inflation
Author: Michael D. Bordo
Publisher: University of Chicago Press
ISBN: 0226066959
Category : Business & Economics
Languages : en
Pages : 545
Book Description
Controlling inflation is among the most important objectives of economic policy. By maintaining price stability, policy makers are able to reduce uncertainty, improve price-monitoring mechanisms, and facilitate more efficient planning and allocation of resources, thereby raising productivity. This volume focuses on understanding the causes of the Great Inflation of the 1970s and ’80s, which saw rising inflation in many nations, and which propelled interest rates across the developing world into the double digits. In the decades since, the immediate cause of the period’s rise in inflation has been the subject of considerable debate. Among the areas of contention are the role of monetary policy in driving inflation and the implications this had both for policy design and for evaluating the performance of those who set the policy. Here, contributors map monetary policy from the 1960s to the present, shedding light on the ways in which the lessons of the Great Inflation were absorbed and applied to today’s global and increasingly complex economic environment.

The Financial Crisis Inquiry Report

Category : Political Science
Languages : en
Pages : 692
Book Description
The Financial Crisis Inquiry Report, published by the U.S. Government and the Financial Crisis Inquiry Commission in early 2011, is the official government report on the United States financial collapse and the review of major financial institutions that bankrupted and failed, or would have without help from the government. The commission and the report were implemented after Congress passed an act in 2009 to review and prevent fraudulent activity. The report details, among other things, the periods before, during, and after the crisis, what led up to it, and analyses of subprime mortgage lending, credit expansion and banking policies, the collapse of companies like Fannie Mae and Freddie Mac, and the federal bailouts of Lehman and AIG. It also discusses the aftermath of the fallout and our current state. This report should be of interest to anyone concerned about the financial situation in the U.S. and around the world.THE FINANCIAL CRISIS INQUIRY COMMISSION is an independent, bi-partisan, government-appointed panel of 10 people that was created to "examine the causes, domestic and global, of the current financial and economic crisis in the United States." It was established as part of the Fraud Enforcement and Recovery Act of 2009. The commission consisted of private citizens with expertise in economics and finance, banking, housing, market regulation, and consumer protection. They examined and reported on "the collapse of major financial institutions that failed or would have failed if not for exceptional assistance from the government."News Dissector DANNY SCHECHTER is a journalist, blogger and filmmaker. He has been reporting on economic crises since the 1980's when he was with ABC News. His film In Debt We Trust warned of the economic meltdown in 2006. He has since written three books on the subject including Plunder: Investigating Our Economic Calamity (Cosimo Books, 2008), and The Crime Of Our Time: Why Wall Street Is Not Too Big to Jail (Disinfo Books, 2011), a companion to his latest film Plunder The Crime Of Our Time.

And Yet it Moves
Author: David Miles
Publisher: Geneva Reports on the World Ec
ISBN: 9781912179053
Category : Business & Economics
Languages : en
Pages : 128
Book Description
Over the last decade, the developed world has been hit by the deepest recession since the Great Depression and a rollercoaster in commodity prices. And yet, core inflation has been both low and fairly stable. A rule of thumb that inflation is always near 2%, though more often than not just a bit below, has been quite reliable. The young, or those with short memories, could be forgiven for looking condescendingly at their older friends who speak of inflation as a major economic problem. But, like Galileo Galilei told his contemporaries who thought the Earth was immovable, "Eppur si muove" ("and yet it moves"). Since most societies regard stable inflation as a goal, it is tempting to describe this solid anchoring of inflation as a great achievement of monetary policy. But what if it was just luck? Will the great anchoring soon lead a great bout of inflation, just as the Great Moderation was followed by the Great Recession? Do we need to change the way in which policy is set to better handle changed circumstances since the financial crash? The 19th Geneva Report on the World Economy starts by analysing outcomes across countries for the last ten years. Inflation is compared with its behaviour in the period before the financial crash to assess the extent to which it really has been stable, what the proximate causes are, and whether it will stay low in future. The report then assesses theories of inflation in light of these facts, and tries to make sense of them. Next, the report turns to the question we posed at the start: was it good policy or good luck that prevented severe deflation and kept inflation relatively steady? A description of what policies were adopted and how they interacted with economic shocks informs the conclusions on appropriate policies--both monetary and fiscal--for the future. The report pays particular attention tothe role of central banks and the extent of their activities.

Hysteresis and Business Cycles
Author: Ms.Valerie Cerra
Publisher: International Monetary Fund
ISBN: 1513536990
Category : Business & Economics
Languages : en
Pages : 50
Book Description
Traditionally, economic growth and business cycles have been treated independently. However, the dependence of GDP levels on its history of shocks, what economists refer to as “hysteresis,” argues for unifying the analysis of growth and cycles. In this paper, we review the recent empirical and theoretical literature that motivate this paradigm shift. The renewed interest in hysteresis has been sparked by the persistence of the Global Financial Crisis and fears of a slow recovery from the Covid-19 crisis. The findings of the recent literature have far-reaching conceptual and policy implications. In recessions, monetary and fiscal policies need to be more active to avoid the permanent scars of a downturn. And in good times, running a high-pressure economy could have permanent positive effects.

Languages : en
Pages : 475
Book Description
This year marks the tenth anniversary of the 2009 global recession. Most emerging market and developing economies weathered the global recession relatively well, in part by using the sizable fiscal and monetary policy ammunition accumulated during prior years of strong growth. However, their growth prospects have weakened since then, and many now have less policy space. This study provides the first comprehensive stocktaking of the past decade from the perspective of emerging market and developing economies. Many of these economies have now become more vulnerable to economic shocks. The study discusses lessons from the global recession and policy options for these economies to strengthen growth and prepare for the possibility of another global downturn.

The American Business Cycle
Author: Robert J. Gordon
Publisher: University of Chicago Press
ISBN: 0226304590
Category : Business & Economics
Languages : en
Pages : 882
Book Description
In recent decades the American economy has experienced the worst peace-time inflation in its history and the highest unemployment rate since the Great Depression. These circumstances have prompted renewed interest in the concept of business cycles, which Joseph Schumpeter suggested are "like the beat of the heart, of the essence of the organism that displays them." In The American Business Cycle, some of the most prominent macroeconomics in the United States focuses on the questions, To what extent are business cycles propelled by external shocks? How have post-1946 cycles differed from earlier cycles? And, what are the major factors that contribute to business cycles? They extend their investigation in some areas as far back as 1875 to afford a deeper understanding of both economic history and the most recent economic fluctuations. Seven papers address specific aspects of economic activity: consumption, investment, inventory change, fiscal policy, monetary behavior, open economy, and the labor market. Five papers focus on aggregate economic activity. In a number of cases, the papers present findings that challenge widely accepted models and assumptions. In addition to its substantive findings, The American Business Cycle includes an appendix containing both the first published history of the NBER business-cycle dating chronology and many previously unpublished historical data series.
