16 Afterword
Foreword
Unemployment has been a principal preoccupation of critical economists, policymakers, and ordinary citizens in twentieth-century America. This volume combines economic theory and economic history to provide some provocative insights into how a “modern” approach to unemployment evolved, and why, in the authors’ judgment, it ultimately failed.
The authors raise important issues: What has determined the volume of unemployment in America? Can the “macro” issues of full employment and output determination be explained in terms of a “micro” analysis of leading markets, particularly that for labor? Have revolutionary twentieth-century changes in economic thinking regarding unemployment policies served to befriend or harm workers and business interests? Have good intentions been overcome by unintended adverse consequences of policy actions?
In tackling these questions, this book uses empirical analysis and theoretical insight that are both instructive and illuminating. Vedder and Gallaway are not unique in suggesting that government unemployment policies have ultimately proven unsuccessful, but their blend of historical and theoretical insights makes the case in a more compelling and comprehensive fashion than other explorations into the unemployment problem. Combining the microeconomic theory of labor markets with some simple but powerful statistical analysis of twentieth-century American experience, they present a strong argument for the position that market adjustments explain cycles in employment activity and have outperformed nonmarket interventions as tools for achieving economic stability.
To be sure, the principal theses of Professors Vedder and Gallaway will doubtless impress some readers as distillations from “quaint and curious volumes of forgotten lore.” To avoid or mitigate such reactions is, as I see it, the function of these introductory notes.
Our authors’ principal, and admittedly heterodox theses are only two in number, the second thesis being a corollary of the first:
Their first thesis is a matter of theoretical economics. Unemployment is related directly to real-wage rates (adjusted over time for the “quality” and productivity of the labor involved). The British neoclassical economist Edwin Cannan put the point in one sentence in mid-Depression 1932: “General unemployment appears when asking too much is a general phenomenon.”1
Vedder and Gallaway’s second thesis is a matter of American economic history. They apply their first thesis to the American record in the twentieth century, claiming that the average or “natural” rate of unemployment2 in the United States has in the last generation been rising, by reason of such governmental policies as minimum wages, social security, unemployment relief, affirmative action, and the encouragement of trade-union collective bargaining.
As recently as the first third of the present century, the first of the Vedder-Gallaway theses would not have deserved the title of “thesis.” Rather, it was regarded by orthodox economists as a truism, too obvious to warrant either quantitative or historical investigation. Mere restatement sufficed, despite a significant volume of dissent from liberals, socialists, and under-consumptionists led by the economist John A. Hobson, the industrialist Henry Ford, and (as Vedder and Gallaway delight in reminding us) the public figure and eventual President Herbert Hoover.3
Now, of course, the shoe is on the other foot, and the Vedder-Gallaway sort of investigation remains under a cloud. It is no longer the truism it once was; instead, it has come to be regarded as something of a heresy. J. B. Say’s complacent “economic law” about “aggregate supply being, or creating, its own demand” is largely replaced by “Keynes’s Law”4 about “aggregate demand creating its own supply” in the presence of significant unemployment. If aggregate demand is all that matters (in the presence of significant unemployment), concern with wages as costs of production and resistance to upward pressure on either money or real wages are wrong a priori.
Out of Work comprises fifteen chapters. The first three chapters, with the assistance of a technical appendix that contains a formal model of a macroeconomy, derive, compare, and examine direct econometric relations between measured unemployment rates (dependent variables) and real-wage levels adjusted for productivity changes and sometimes lagged over time (independent variables). For the quantitative economist as for the statistician, these constitute the case for the Vedder-Gallaway thesis. The last three chapters are the moral of the tale, which is that public policy has been systematically wrong-headed since approximately 1930, and that the role of market forces in labor relations should be restored to approximately its pre-1930 importance. The intervening nine chapters deal in chronological order with particular periods and incidents in twentieth-century American economic history, from the so-called “Golden Age” of the century’s first generation (1900-30) through the so-called “Reagan Revolution” of the 1980s to the present. To the noneconomist, especially if brought up in the liberal or Keynesian environment of 1930–70, these are at once the most intelligible and the most challenging portions of the book as a whole.
Collectively, the contents of this book seem bound to inspire for many, if not most, readers a combination of surprises and questions. In my own case, for instance, my curiosity was continually piqued by such issues as:
• The underlying rationale for the change in adjusted real wage rates that drive the Vedder and Gallaway analysis.
• The role of public fiscal policies, public monetary policies, and public international-economic policies (not aimed primarily at labor-market developments) in influencing the behavior of the Vedder-Gallaway model.
• The importance of the embryonic or aborted “planned economy” of World War I as perhaps a dress rehearsal for the New Deal controls fifteen years later—with some of the same controllers not only involved, but elevated to higher positions with more authority.
• The impact of the sharp disinflation of 1920–22—the last “business cycle” of the nineteenth-century type—which aroused so much “compassionate” reflationary advocacy, so much wage-maintenance sentiment, and so many gloomy forecasts for the 1920s as it apparently did.
• How the Vedder-Gallaway conclusions fit with the argument offered by many Keynesians that if downward wage and price flexibility had continued after 1932, it would have led to “hyperdeflation”—an accelerated version of the 1865–96 deflation—rather than to economic recovery.
• The significance of the Vedder-Gallaway model for the role of monetarism in economic thinking.
• Their handling of the World War II (1940-46) era, when scarcities and black markets obscured the meaning of published consumer prices and real wages, and the composition of the national output changed in ways that cast doubt on the comparability of productivity estimates for those years with similar data for earlier and later periods. The easy and natural escape from these difficulties for many statistical analyses has been to omit some or all of these war years from their time-series regressions and correlations.
