This working paper contrasts the neo-Keynesian and post-Keynesian theories of monetary policy for an open economy, highlighting the irrelevance of the orthodox theory and the explanatory capacity of heterodoxy for an emerging economy such as Mexico. It focuses on the role of the central bank and the case of the Mexican currency during the economic recovery after the Great Lockout. In the first section, we criticize two proposals of the 3-Equation New-Keynesian model, concluding that, implicitly, both models reaffirm the extreme neutrality of money and the exchange rate in both the short and the long runs. In contrast, we analyze the post-Keynesian exchange rate model proposed by John T. Harvey (2009). In addition, we rely on the fundamentals of the heterodox school of thought such as the financial instability hypothesis of Hyman Minsky (1994) and the relevance of capital flows for the determination of the exchange rate and its implications for economic growth and prices by Jan Kregel (2008). Finally, the erratic behavior of the excessive appreciation of the Mexican Super Peso against the dollar after the recovery of the COVID-19 crisis and in the context of global risk is presented.

This paper critically reviews both mainstream and Keynesian empirical studies of interest rate dynamics. It assesses the key findings of a selected number of these studies, surveying the debates between the mainstream and the Keynesian schools. It also explores the debates on interest rate dynamics within the Post Keynesian school of thought. Lastly, the paper identifies the critical questions relevant for future empirical research.

This paper revisits Keynes’s (1930) essay titled “The economic possibilities for our grandchildren.” We discuss the three broader trends identified by Keynes that he expected would come to characterize the socio-economic evolution of advanced countries under individualistic capitalism: first, continued technological progress and capital accumulation as the main drivers of exponential growth in economic possibilities; second, a gradual general rebalancing of life choices away from work; and third, a change in the code of morals in societies approaching an envisioned stationary state of zero net capital accumulation in which mankind has solved its economic problem and enjoys a lifestyle predominantly framed by leisure rather than disutility-yielding work. We assess actual outcomes by 2023 and attempt to peek into the future economic possibilities for this generation’s grandchildren.

In recalling John Maynard Keynes’s revolutionary theory of interest, reviewing the doctrines Keynes sought to overthrow, and analyzing the structural transformations of the US economy, James K. Galbraith maintains there is no alternative to a policy of low interest rates. However, such a policy cannot be effective, he argues, without a radical restructuring of the US economy as a whole.

This paper provides a theoretical explanation of the accumulation process, which accounts for the developments in the financial markets over the recent past. Specifically, our approach is focused on the presence of correlations between physical and financial investment, and how the latter could affect the former. In order to achieve this objective, two assets are considered: equities and bonds. This choice permits us to account for two extreme alternative possibilities: taking risk in the short run with unknown profits, or undertaking a commitment to the long run with known yields. This proposal also accounts for the influence of the cost of external finance and the impact of financial uncertainty, as proxied by the interest rate in the former case and the exchange rate in the latter case; thereby utilizing the Keynesian notion of conventions in the determination of investment. The model thus formulated is subsequently estimated by applying the difference GMM and the system GMM in a panel of 14 OECD countries from 1970 to 2010.

In this paper I will follow Hyman Minsky in arguing that the postwar period has seen a slow transformation of the economy from a structure that could be characterized as “robust” to one that is “fragile.” While many economists and policymakers have argued that “no one saw it coming,” Minsky and his followers certainly did! While some of the details might have surprised Minsky, certainly the general contours of this crisis were foreseen by him a half century ago. I will focus on two main points: first, the past four decades have seen the return of “finance capitalism”; and second, the collapse that began two years ago is a classic “Fisher-Minsky” debt deflation. The appropriate way to analyze this transformation and collapse is from the perspective of what Minsky called “financial Keynesianism”—a label he preferred over Post Keynesian because it emphasized the financial nature of the capitalist economy he analyzed.

The Queen of England famously asked her economic advisers why none of them had seen “it” (the global financial crisis) coming. Obviously, the answer is complex, but it must include reference to the evolution of macroeconomic theory over the postwar period—from the “Age of Keynes,” through the Friedmanian era and the return of Neoclassical economics in a particularly extreme form, and, finally, on to the New Monetary Consensus, with a new version of fine-tuning. The story cannot leave out the parallel developments in finance theory—with its efficient markets hypothesis—and in approaches to regulation and supervision of financial institutions.

This paper critically examines these developments and returns to the earlier Keynesian tradition to see what was left out of postwar macro. For example, the synthesis version of Keynes never incorporated true uncertainty or “unknowledge,” and thus deviated substantially from Keynes’s treatment of expectations in chapters 12 and 17 of the General Theory. It essentially reduced Keynes to sticky wages and prices, with nonneutral money only in the case of fooling. The stagflation of the 1970s ended the great debate between “Keynesians” and “Monetarists” in favor of Milton Friedman’s rules, and set the stage for the rise of a succession of increasingly silly theories rooted in pre-Keynesian thought. As Lord Robert Skidelsky (Keynes’s biographer) argues, “Rarely in history can such powerful minds have devoted themselves to such strange ideas.” By returning to Keynes, this paper attempts to provide a new direction forward.

The Role of Government and Fiscal Policy in Modern Macroeconomics

In the face of the dramatic economic events of recent months and the inability of academics and policymakers to prevent them, the New Consensus Macroeconomics (NCM) model has been the subject of several criticisms. This paper considers one of the main criticisms lodged against the NCM model, namely, the absence of any essential role for the government and fiscal policy. Given the size of the public sector and the increasing role of fiscal policy in modern economies, this simplifying assumption of the NCM model is difficult to defend. This paper maintains that conventional arguments used to support this controversial assumption—including historical reasons, theoretical propositions, and practical issues—do not have solid foundations. There is, in fact, nothing inherently monetary in the stabilization policies found in the model. Thus, fiscal policy could play a role at least as important as monetary policy in the NCM model.

Unemployment was singled out by John Maynard Keynes as one of the principle faults of capitalism; the other is excessive inequality. Obviously, there is some link between these two faults: since most people living in capitalist economies must work for wages as a major source of their incomes, the inability to obtain a job means a lower income. If jobs can be provided to the unemployed, inequality and poverty will be reduced—although such policy will not directly address the problem of excessive income at the top of the distribution. Most importantly, Keynes wanted to put unemployed labor to work—not digging holes, but in socially productive ways. This would help to ensure that the additional effective demand created by government spending would not be exhausted in higher prices as it ran up against bottlenecks or other supply constraints. Further, it would help maintain public support for the government’s programs by providing useful output. And it would generate respect for, and feelings of self-worth in, the workers employed in these projects (no worker would want to spend her days digging holes that serve no useful purpose). President Roosevelt’s New Deal jobs programs (such as the Works Progress Administration and the Civilian Conservation Corps) are good examples of such targeted job-creating programs. These provided income and employment for workers, actually helped increase the nation’s productivity, and left us with public buildings, dams, trails, and even music that we still enjoy today. As our nation (and the world) collapses into deep recession, or even depression, it is worthwhile to examine Hyman P. Minsky’s comprehensive approach to resolving the unemployment problem.
