The Unit of Account, Inflation, Leverage, and Financial Fragility

We hope to model financial fragility and money in a way that captures much of what is crucial in Hyman Minsky’s financial fragility hypothesis. This approach to modeling Minsky may be unique in the formal Minskyan literature. Namely, we adopt a model in which a psychological variable we call financial prudence (P) declines over time following a financial crash, driving a cyclical buildup of leverage in household balance sheets. High leverage or a low safe-asset ratio in turn induces high financial fragility (FF). In turn, the pathways of FF and capacity utilization (u) determine the probabilistic risk of a crash in any time interval. When they occur, these crashes entail discrete downward jumps in stock prices and financial sector assets and liabilities. To the endogenous government liabilities in Hannsgen (2014), we add common stock and bank loans and deposits. In two alternative versions of the wage-price module in the model (wage–Phillips curve and chartalist, respectively), the rate of wage inflation depends on either unemployment or the wage-setting policies of the government sector. At any given time t, goods prices also depend on endogenous markup and labor productivity variables. Goods inflation affects aggregate demand through its impact on the value of assets and debts. Bank rates depend on an endogenous markup of their own. Furthermore, in light of the limited carbon budget of humankind over a 50-year horizon, goods production in this model consumes fossil fuels and generates greenhouse gases.

The government produces at a rate given by a reaction function that pulls government activity toward levels prescribed by a fiscal policy rule. Subcategories of government spending affect the pace of technical progress and prudence in lending practices. The intended ultimate purpose of the model is to examine the effects of fiscal policy reaction functions, including one with dual unemployment rate and public production targets, testing their effects on numerically computed solution pathways. Analytical results in the penultimate section show that (1) the model has no equilibrium (steady state) for reasons related to Minsky’s argument that modern capitalist economies possess a property that he called “the instability of stability,” and (2) solution pathways exist and are unique, given vectors of initial conditions and parameter values and realizations of the Poisson model of financial crises.

If the Congressional Budget Office’s recent projections of government revenues and outlays come to pass, the United States will not grow fast enough to bring down the unemployment rate between now and 2016. The public sector deficit will decline from present levels, endangering the sustainability of the recovery. But as this new Strategic Analysis shows, a public sector stimulus of a little over 1 percent of GDP per year focused on export-oriented R & D investment would increase US competitiveness through export-price effects, resulting in a rise of net exports, and slowly lower unemployment to less than 5 percent by 2016. The improvement in net export demand would allow the US economy to enter a period of aggregate-demand rehabilitation—with very encouraging consequences at home. 

With quantitative easing winding down and the latest payroll tax-cut measures set to expire at the end of this year, pressing questions loom about the current state of the US economic recovery and its ability to sustain itself in the absence of support from monetary and fiscal policy.

Four Fragile Markets, Four Years Later

In this brief, Research Scholar Greg Hannsgen and President Dimitri B. Papadimitriou focus on the risks and possibilities ahead for the US economy. Using a Keynesian approach and drawing from the commentary of other observers, they analyze publicly available data in order to assess the strength and durability of the expansion that probably began in 2009. They focus on four broad groups of markets that have shown signs of stress for the last several years: financial markets, markets for household goods and services, commodity markets, and labor markets. This kind of analysis does not yield numerical forecasts but it can provide important clues about the short-term outlook for the country’s economic well-being, and cast light on some longer-run threats. In particular, dangers and stresses in the financial and banking systems are presently very serious, and labor market data show every sign of a widespread and severe weakness in aggregate demand. Unless there is new resolve for effective government action on the jobs front, drastic cuts in much-needed federal, state, and local programs will become the order of the day in the United States, as in much of Europe.

The paper examines three aspects of a financial crisis of domestic origin. The first section studies the evolution of a debt-financed consumption boom supported by rising asset prices, leading to a credit crunch and fluctuations in the real economy, and, ultimately, to debt deflation. The next section extends the analysis to trace gradual evolution toward Ponzi finance and its consequences. The final section explains the link between the financial and the real sector of the economy, pointing to an inherent liquidity problem. The paper concludes with comments on the interactions between the three aspects.
