Despite the plethora of research on market orientation, our understanding of how different dimensions of market orientation interact with each other in generating new intelligence for marketing programs is limited. In this paper, we develop and test a model that examines the interaction effects of the three dimensions of market orientation—customer orientation, competitor orientation, and cross...

This paper proposes a new two stage least squares (2SLS) estimator which is consistent and asymptotically normal in the presence of many weak instruments and heteroskedasticity. The first stage of the estimator consists of two components: first, an adaptive absolute shrinkage and selection operator (LASSO) that selects the instruments; and second, an OLS regression with the selected regressors....

This paper examines whether or not immigration has a positive influence on the duration of unemployment, in a macroeconomic perspective. We analyse also whether the degree of labor market integration can influence migration. The integration of immigrants into the labor market is a recurrence theme in the work on the economic consequences of immigration. However, to our knowledge, no researchers...

Listed companies are the pillar strength of China’s economy, whose CSR performance is great significance. From perspective sustainable development enterprises, this paper finds that managerial myopia will inhibit enterprises from fulfilling their social responsibilities. Using employment opportunity indicator as an instrumental variable, result 2SLS regression remains significantly negative. In...

The exchange rate unification is one of the most important instruments of economic adjustment, which is used in many countries. This paper shows the effects of the exchange rate unification on price level (inflation), gross domestic production (GDP), non-oil exports, private conception, government expenditure and stock of money. The data, is used related to the period 1959-2000. To analyze the ...

Abstract. Credible inference requires attention to the possible fragility of the results (p-values for key hypothesis tests) to flaws in the model assumptions, notably including the validity of the instruments used. Past sensitivity analysis has mainly consisted of experimentation with alternative model specifications and with tests of over-identifying restrictions. We provide a feasible sensit...

Abstract. Credible inference requires attention to the possible fragility of the results (p-values for key hypothesis tests) to flaws in the model assumptions, notably accounting for the validity of the instruments used. Past sensitivity analysis has mainly consisted of experimentation with alternative model specifications and with tests of over-identifying restrictions which actually presuppos...

In this paper, we present a limiting distribution theory for the break point estimator in a linear regression model with multiple structural breaks obtained by minimizing a Two Stage Least Squares (2SLS) objective function. Our analysis covers both the case in which the reduced form for the endogenous regressors is stable and the case in which it is unstable with multiple structural breaks. For...
