Short‐ and long‐run impacts of gasoline price and macroeconomic factors on road traffic safety in Nigeria

Abstract

This paper examined the short‐ and long‐run impacts of gasoline price, macroeconomic factors and road length on road traffic crashes, injuries and fatalities in Nigeria. Annual data from 1995 to 2019 and autoregressive distributed lag approach were employed. Results suggest that gasoline price, per capita income, road length and population density significantly influence road safety outcomes. Gasoline price has a positive short‐run impact on crashes, injuries, and fatalities contrary to findings in developed countries. Road crashes tend to decrease when income increases in the short term. Population density leads to improvement in road safety outcomes while road length exacerbates it. Government's policy on gasoline price increase could worsen road safety outcomes unless it is accompanied by improvement in road infrastructure, safe public transport and economic growth,

The Dynamic Effect of Trade Openness, Debt, and Foreign Investment in Ghana’s Economy: An ARDL Bound Testing Approach

“…The ARDL model has been widely adopted in recent research studies due to its advantages over other econometric models. One primary advantage of the ARDL is its ability to accommodate variables with differing orders of integration I (0) and I (1) and limited sample sizes [53], [54], [55], [56]. The ARDL model specification used in this study is presented in Equation 2.…”
