Government size and economic growth in Taiwan: A threshold regression approach

The Armey curve developed by [Armey, R. (1995). The freedom revolution. Washington, DO Rognery Publishing Co.] and [Vedder, R. K., & Gallaway, L. E. (1998). Government size and economic growth. Joint Economic Committee] demonstrates that there is a non-linear relationship between government size and economic growth. In order to search for the threshold effects, this paper employs [Hansen, B. E. (2000). Sample splitting and threshold estimation. Econometrica, 68(3), 575-603] threshold regression model to test whether the Armey curve exists in Taiwan, allowing for endogenous government size thresholds. We apply the two-sector production function developed by [Ram, R. (1986). Government size and economic growth: A new framework and some evidence from cross-section and time-series data. American Economic Review, 76(l), 191-203] to construct the threshold regression model. Three classifications of government size are tested in sequence as threshold variables. The result indicates that all three classifications of government size have a threshold effect and that a non-linear relationship of the Armey curve exists in Taiwan.
