Graph-theoretic methods of causal search based on the ideas of Pearl (2000), Spirtes et al. (2000), and others have been applied by a number of researchers to economic data, particularly by Swanson and Granger (1997) to the problem of finding a data-based contemporaneous causal order for the structural vector autoregression, rather than, as is typically done, assuming a weakly justified Cholesk...

The gut microbiome is a dynamic system that changes with host development, health, behavior, diet, and microbe-microbe interactions. Prior work on gut microbial time series has largely focused on autoregressive models (e.g. Lotka-Volterra). However, we show that most of the variance in microbial time series is non-autoregressive. In addition, we show how community state-clustering is flawed whe...

The paper proposes a structural approach to VAR analysis in panels, which takes into account responses to both idiosyncratic and common structural shocks, while permitting full cross member heterogeneity of the response dynamics. In the context of this structural approach, estimation of the loading matrices for the decomposition into idiosyncratic versus common shocks is straightforward and tra...

Agromyzidae (Insecta: Diptera) is a cosmopolitan family of acalyptrate flies, with almost 3,000 species worldwide distributed. Most are leaf miners on large number plants. Among them, Liriomyza Mik, 1894 genus leaf-miner that can cause significant damage to economically important crops and considered agricultural pests, such as sativae Blanchard, 1938 huidobrensis (Blanchard, 1926), which herei...

The objective of this study is to record the injury Anomala testaceipennis Blanchard, 1851 (Coleoptera: Scarabaeidae: Rutelinae) adults in coffee Coffea arabica L. municipality Piumhi, Minas Gerais, Brazil. This first reported A. attacking coffee.

We develop a new model of trade in which educational institutions drive comparative advantage and determine the distribution of human capital within and across countries. Our framework exploits a multiplicity of sectors and the continuous support of human capital choices to demonstrate that freer trade can induce crowding out of the middle occupations towards the skill acquisition extremes in o...

This article examines the structural responses of foreign exchange and equity markets to COVID-19 pandemic in seven Asian countries over its first 4 months (31 December 2019 1 May 2020). Marginal effects derived from a vector autoregression (SVAR) model suggest that 1% increase incidence cases significantly diminished Indonesia’s market returns by 4.7%, depreciated Indian rupee against US dolla...
