  • Corporate Debt in Latin America and its Macroeconomic Implications

    Working Paper No. 904 | May 2018
    This paper provides an empirical analysis of nonfinancial corporate debt in six large Latin American countries (Argentina, Brazil, Chile, Colombia, Mexico, and Peru), distinguishing between bond-issuing and non-bond-issuing firms, and assessing the debt’s macroeconomic implications. The paper uses a sample of 2,241 firms listed on the stock markets of their respective countries, comprising 34 sectors of economic activity for the period 2009–16. On the basis of liquidity, leverage, and profitability indicators, it shows that bond-issuing firms are in a worse financial position relative to non-bond-issuing firms. Using Minsky’s hedge/speculative/Ponzi taxonomy for financial fragility, we argue that there is a larger share of firms that are in a speculative or Ponzi position relative to the hedge category. Also, the share of hedge bond-issuing firms declines over time. Finally, the paper presents the results of estimating a nonlinear threshold econometric model, which demonstrates that beyond a leverage threshold, firms’ investment contracts while they increase their liquidity positions. This has important macroeconomic implications, since the listed and, in particular, bond-issuing firms (which tend to operate under high leverage levels) represent a significant share of assets and investment. This finding could account, in part, for the retrenchment in investment that the sample of countries included in the paper have experienced in the period under study and highlights the need to incorporate the international bond market in analyses of monetary transmission mechanisms.

  • Inside Money in a Kaldor-Kalecki-Steindl Fiscal Policy Model

    Working Paper No. 839 | June 2015
    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.
