How productive is infrastructure? new approach and evidence from rural India por Zhang, Xiaobo, Fan, Shenggen

“…To help reconcile this debate, this paper proposes that researchers should first test for causality in their data to check for length of lagged relationships and the existence of reverse causality, as a critical step before specifying a final model and estimating procedure on the relationship between the stock of capital and productivity growth. …”

Do health investments improve agricultural productivity: Lessons from agricultural household and health research por McNamara, Paul E., Ulimwengu, John M., Leonard, Kenneth L.

“…While the link can readily be seen in descriptive statistics, however, it is another matter to disentangle the precise nature of the connection. It is likely that causality runs in both directions, and both health and prosperity clearly are affected by numerous other variables.…”

The impacts of weather and climate information services on technical efficiency and farm productivity among smallholder farmers in the Upper West Region of Ghana por Djido, Abdoulaye, Houessionon, Prosper, Nikoi, Gordon, Ouédraogo, Issa, Ouédraogo, Mathieu, Segnon, Alcade C, Zougmoré, Robert B.

“…Thirdly, we employ a Recursive Structural Equation System to deal with the simultaneous problems of the endogenous treatment of CIS into Y, the endogenous covariate of TE into Y, and the reverse causality between Y and TE. Overall, our findings are robust to the different methodologies with strong evidence that the pilot project through the adoption of CIS has a substantial positive effect on improving TE and Y in the study area. …”

The impact of changes in government policies on economic performance (the ARCH model) por Mendoza, Meyra Sebello, Farris, Paul L.

“…The impact of changes in government policy from direct control to free market on spatial market integration is investigated with a bivariate exponential autoregressive of impact of new information on price discovery between geographic markets during conditional heteroskedasticity (ARCH) model. Causal relationships and the magnitude different policy regimes are determined by the Granger causality test and dynamic multipliers, respectively. …”

Welfare dynamics in rural Kenya and Madagascar por Barrett, Christopher B., Marenya, Paswel Phiri, McPeak, J.G., Minten, Bart, Murithi, F., Oluoch-Kosura,Willis, Place, Frank, Randrianarisoa, J.C., Rasambainarivo, J., Wangila, J.

“…This paper presents comparative qualitative and quantitative evidence from rural Kenya and Madagascar in an attempt to untangle the causality behind persistent poverty. We find striking differences in welfare dynamics depending on whether one uses total income, including stochastic terms and inevitable measurement error, or the predictable, structural component of income based on a household's asset holdings. …”
