The objective of this research was to determine the effect of corruption on economic growth in Peru for the period 1998-2018. It was determined how economic growth was affected both in the short and long term by corruption. The corruption control index was used to measure corruption and the variation in gross domestic product (GDP) at constant prices was used to measure economic growth. To determine this effect, the hypothetical deductive method was used as a general method since we sought to corroborate a hypothesis and as a specific method, we used the Autoregressive Model of Distributed Lag (ARDL) since this model adapts well to small samples, likewise we had a non-experimental research design – longitudinal explanatory. Data were collected from the World Bank and the Ministry of Education (MINEDU) from 1998 to 2018. As a result of the econometric ARDL model, it was obtained that corruption had a negative effect on economic growth since an improvement of one percentage point in the corruption index would mean an improvement of 0.55 percentage points in economic growth. Therefore, it is concluded that the effect of corruption has a negative effect on economic growth as expected according to the reviewed antecedents.

This paper examines the impact of corruption on employers' efficiency in Vietnamese firms. The Generalized Least Square (GLS) estimation method was used for data sets surveyed for Vietnamese firms in 63 localities. The research results show that the unofficial costs in the industry and the total informal costs accounting for 10% or more of revenue will negatively affect the labor efficiency of these enterprises.

This paper investigates the effects of corruption and long-term investment of businesses in Vietnam using the General Least Square (GLS) estimation method for businesses in 63 provinces in Vietnam from 2016-2018. The results show that corruption was an important factor affecting the long-term investment decisions of Vietnamese enterprises. The ability to predict corruption of businesses can explain the phenomenon of part of the cash flow of businesses flowing out of production and business. Informal costs related to low-level administrative procedures act as “grease” to help businesses reduce time costs, but when the total amount of unofficial expenses exceeds 10% of revenue of businesses, they become a burden for businesses and restrain them from making long-term investments. Corrupted public officials' behavior has led businesses to misallocate resources and prevent them from making long-term investments. The result shows that the East Asia paradox holds only for the case of informal costs related to administrative procedures in Vietnam.
