The study examined the penetration of financial inclusion in the agricultural sector, using small-scale farmers in Enugu State, Nigeria, as evidence.

The study utilized survey data generated from 425 questionnaires administered to small-scale farmers in both rural and urban locations in Enugu State. The study applied the adequacy gap, timeliness gap and penetration gap indices to measure the penetration of financial inclusion among the small-scale farmers in Enugu State.

It was found that different lending agencies, except for some cooperative societies, were unable to meet the credit needs of small-scale farmers in Enugu State as shown by the adequacy gap index. The timeliness gap index revealed the existence of time gap in the credit receipt of small-scale farmers given that agriculture is rain-fed in Enugu. The penetration gap index indicated that there is gap in the penetration of agricultural credit grants to small-scale farmers in Enugu State, showing a shallow penetration of financial inclusion in agricultural sector.

The research is limited in scope as a result of data and the desire to study small-scale farmers in Enugu State, Nigeria.

The study recommended among others that government should encourage cooperatives more to meet credit needs of farmers in order to raise the level of financial inclusion penetration.

To the best of the authors' knowledge, this is the only study that examines the penetration of financial inclusion among small-scale farmers in Enugu State, Nigeria. This study contributes to the growing literature on financial inclusion in the agricultural sector as there is dearth of literature in this study area.

This study aims to make a comparative study of the applicability of the purchasing power parity (PPP) in selected less developing countries (LDCs) on one hand and European countries on the other hand.

The research design is empirical and ex post facto. This study uses an assortment of co-integration tests and error correction representation. The chosen approach allows for the consideration of long-run elasticities and the dynamics of the short-run adjustment of exchange rates to changes in domestic and foreign prices. Monthly data are used for the period 1980:1 through 2015:12 (i.e. 432 observations).

Results from long-run co-integration analysis, short-run error correction models and persistence profile analysis overwhelmingly confirm the validity of PPP in these two sets of countries regardless the disparity in their relative exchange rate and price characteristics.

Curiously, several of these empirical studies and still many more, have focused their attention on the experiences of industrialized countries, with a few investigations devoted to LDCs. The evidence is even scarcer in Africa. Clearly, the acceptance of any hypothesis as a credible explanation of economic reality hinges on the robustness of the hypothesis across countries with different economic and institutional frameworks.

Knowledge of the extent to which exchange rate and relative prices can be linked in the long run is important for the design and management of inflation and the implementation of monetary policy. For instance, policy actions aimed at stabilizing the domestic economy can obtain results that are, at best, uncertain in the absence of correct characterization of the PPP dynamics. Moreover, structural and macroeconomic adjustment programs implemented in these countries to achieve economic growth and external competitiveness could be unsuccessful if flawed estimates of PPP exchange rates are retained.

Several empirical studies have been done to prove the validity or otherwise of the PPP. Unlike prior authors, this study makes a comparative study of the applicability of the PPP in selected LDC on one hand and European countries.

Despite the government’s efforts to protect domestic industries from foreign competition through tariffs, the industrial sector’s contribution to GDP continued to decline in Nigeria. Based on the scenario, this study assessed the symmetric and asymmetric effects of tariffs on industrial performance in Nigeria for the period 1988–2021. Tariff was captured with a tariff rate applied to the weighted mean of all products, while industry value added as a percent of GDP was used as a proxy for industrial performance.

Linear and nonlinear ARDL techniques were used for the analysis.

The symmetric (linear ARDL) results revealed that tariffs have a significant positive effect on industrial performance in both the short and long term. The asymmetric (nonlinear ARDL) results showed that a long-term asymmetry exists between tariffs and industrial performance. It revealed positive effects on industrial performance for both positive and negative tariff changes, with the negative change having a greater impact.

Generally, the results showed that the use of tariffs to protect domestic industries in Nigeria promotes industrial performance. The implication is that the declining contribution of the industrial sector to GDP in Nigeria is not a result of the tariff policy. It shows that the government should look beyond tariff policy to enhance the industrial contribution to GDP.

Nigeria should exercise caution in using tariff policies to protect domestic industries to avoid retaliation from their trade partners that could reverse the positive impacts.
