As a typical technology-intensive industry, the renewable energy industry is standard sample for scholars to study R&D innovation of enterprises. At present, strongly supported by government subsidy policy in China and has developed rapidly recent years. Its own financing constraints lack power are also main problems development Taking A-share enterprises from 2016 2020 as research object, ...

The aim of this paper is to assess the sign and magnitude of the nonlinear effects of main socio-economic variables as well as the financial development index(measured by private credit to GDP ratio) on the environmental pollution. Specifically, the interaction of the socio-economic variables with financial development as a threshold variable in affecting CO2 emission is studied. In this respec...

This paper estimates threshold regression models with an endogenous variable using a nonparametric control function approach. Assuming diminishing effects, we derive the consistency and limiting distribution of our proposed estimator constructed from series approximation method for weakly dependent data. In addition, propose test endogeneity variable, which is valid regardless whether effects e...

to study the effect of urea application in safflower (carthamus tinctorius) and determination of effective traits on its yield, a factorial experiment based on randomized complete block design in three replications was conducted in tabriz, iran, during 2012. studied factors were urea rate levels as 100, 150 and 200 kg/ha and urea application times 100% in sowing time, 50% sowing time + 50% stem...

This study constructs a panel threshold regression model to explore the price impact of foreign institutional herding of firms listed in the Taiwan Stock Exchange during January 2000 to June 2008. Our panel threshold model is constructed to explore the price impact of foreign institutional investors’ herding in the Taiwan stock market after controlling the firm size. By examining the presence o...

Using panel data we investigate the relationship between income inequality and economic development. We employ a threshold regression model that allows for endogenous income thresholds and find strong evidence of a two-regime split in our sample.  2000 Elsevier Science S.A. All rights reserved.
