This paper proposes a new test of the null hypothesis that a generalized method of moments model is identified. The test can detect local or global underidentification, and underidentification in some or all directions. The idea of the test is to compare the volume of two confidence sets - one...

A hipótese de mercados eficientes é um assunto de grande relevância dentro da teoria de finanças. Assim, este trabalho tem por objetivo verificar a presença de eficiência no mercado à vista e futuro de boi gordo no Brasil, no período de março de 2001 a maio de 2010, totalizando 2.300...

Corporate venture capital (CVC) investors are regularly painted with the same brush, a fact underscored by the often observed belief in the extant literature that corporate venture capitalists (CVCs) form a homogeneous group. In contrast to this simplifying perspective, this paper categorizes...

This paper proposes a novel approach to uncover the linkages of the housing market and macroeconomy for fifteen OECD countries. One of the limitations of conventional approach is that it does not distinguish the time domain from the frequency domain. However, econometric and economic rationale...

In this paper, we propose a new method to assess the impact of sovereign ratings on sovereign bond yields. We estimate the impulse response of the interest rate, following a change in the rating. Since ratings are ordinal and moreover extremely persistent, it proves difficult to estimate those...

This paper analyzes the effects of public R&D funding on R&D expenditure and patenting behavior of German firms. The main focus is the direct impact of subsidies on R&D and the indirect effect on innovation output measured by patent applications. We distinguish the productivity of purely...

In this note, we build upon the asymptotic theory for GARCH processes, considering the general class of augmented GARCH(p, q) processes. Our contribution is to complement the well-known univariate asymptotics by providing a bivariate functional central limit theorem between the sample quantile...

Partial derivatives have a special place in economics since the marginal revolution of the 1850s. We present results from multivariate partial derivative estimates using nonlinear non-parametric regressions in a finite difference method, accessible via the R-package NNS. Numerical partial...

This paper uses the Fourier flexible form to jointly approximate utility and service flows from durable and nondurable goods. In contrast, parametric functions are usually not flexible enough to accurately approximate nonseparability and often give inconsistent results. This paper calls these...
