Building on a recently developed methodology for sensitivity analysis that parametrizes omitted variable bias in terms of partial R2 measures, I propose a simple statistic to capture the severity of omitted variable bias in any observational study: the probability of omitted variable bias...

Covariate benchmarking is an important part of sensitivity analysis about omitted variable bias and can be used to bound the strength of the unobserved confounder using information and judgments about observed covariates. It is common to carry out formal covariate benchmarking after...

In this paper, I discuss three aspects of the Frisch-Waugh-Lovell theorem. First, I show that the theorem holds for linear instrumental variables estimation of a multiple regression model that is either exactly or overidentified. I show that with linear instrumental variables estimation: (a)...

Covariate benchmarking is an important part of sensitivity analysis about omitted variable bias and can be used to bound the strength of the unobserved confounder using information and judgments about observed covariates. It is common to carry out formal covariate benchmarking under the...

In economics, it is common to use dimensioned variables, e.g. earnings (measured in dollars per year), as arguments in the logarithmic function. This is conceptually problematic because a logarithmic function can only take dimensionless quantities as its argument. One way to avoid this...

I discuss some theoretical and empirical points about the Goodwin model. First, I offer a simple proof that solution trajectories around the stable critical point in the Goodwin model are closed orbits but not limit cycles. Moreover, in a neighborhood of the stable critical point, the closed...

I study the effect of technical change on the equilibrium profit rate in Classical-Marxian models of economic growth with alternative closures. In each model, capitalists adopt a new technique of production only if it will increase the profit rate given their expectations about the movement of...

The challenge of employment in the Indian economy, especially after it growth acceleration since the mid-1980s, relates to its quality rather than its quantity. While employment growth has kept pace with the labour force over the long run, what has grown is informal employment. The coexistence...

This paper offers a unified analytical treatment of Marx's theory of ground-rent, building on the analysis that is available in Volume Three of Capital. Since ground-rent is a transformation of surplus profit generated in agriculture, the main argument is developed in two steps. In the first...

Bhaduri and Marglin (1990) had argued that an investment function which has the profit rate and the capacity utilization rates as the two determinants of investment imposes unwarranted restrictions on the macroeconomic model and rules out profit-led expansion. In this paper, I show that this...
