Input subsidies and crop diversity on family farms in Burkina Faso

Since their independence, many countries in sub-Saharan Africa have used input subsidies to increase agricultural productivity and improve food security. We analyse the effects of both a fertiliser and a seed subsidy on farming households' land allocation among crops and crop diversity in Burkina Faso. Although previous studies investigated either the impact of a fertiliser or a seed subsidy on targeted crops, few examined the effects of both subsidies combined. Applying a correlated random-effects model with a control function approach to nationally representative, 2-year panel data collected from farming households, we find that those with access to the fertiliser subsidy allocate more land to the crops it targets (rice, maize and cotton) than non-targeted crops. Focusing on a minor crop with key agronomic and nutritional attributes, we conclude that land allocation to cowpea as the primary crop and intercrop declined with the fertiliser subsidy. The fertiliser subsidy also negatively affects crop diversity. However, we find that the cowpea seed subsidy offsets the bias of fertiliser subsidy toward fertiliser-targeted crops and enhances diversity.     

The Robustness of Corporate Social Responsibility and Brand Loyalty Relation: A Meta-Analytic Examination

Abstract

It is largely believed that genuine corporate efforts to embrace social responsibilities stimulate customers to respond positively to such corporations. However, empirical research about the robustness of corporate social responsibility (CSR) and brand loyalty (BL) yields inconsistent findings. Therefore, we aggregated the results of 43 citations consisting of 28495 observations by means of meta-analysis to examine the robustness of the CSR-BL relationship. The findings of our research revealed that the overall effect size of the CSR and brand loyalty relationship is positive and yields a medium effect size. Furthermore, such a relationship was moderated by several contextual factors. We conclude with a theoretical contribution, managerial implications, limitations, and suggestions for future studies     

Corporate Debt Maturity Structure: The Role of Firm Level and Institutional Determinants in Selected African Countries

An appropriate debt maturity structure is essential for firms to enable them align asset structure to liabilities to prevent a mismatch. This study investigates the role of firm-level and institutional variables on debt maturity structure in selected African countries. Using panel generalised method of moment that addresses endogeneity problem; our findings reveal a dynamic process of adjustment to optimal debt maturity structure. Furthermore, firm-level variables (leverage, asset structure and firm size) provide support for the contracting cost, signalling and matching principle theories of debt maturity structure. Results of institutional variables suggest that better developed institutions promote long-term debt maturity structures.     

Analysing customers' reviews and ratings for online food deliveries: A text mining approach

The purpose of this study was to explore the relationship between online reviews and ratings through text mining and empirical techniques. An Indian food delivery portal ( Zomato.com ) was used, where 50 restaurants on Presence Across Nation (PAN) basis were selected through stratified random sampling. A total of 2530 reviews were collected, scrutinized, and analysed. Using the NVivo software for qualitative analysis, seven themes were identified from collected reviews, out of which, the ‘delivery’ theme was explored further for identifying sub-themes. Linear regression modelling was used to identify the variables affecting delivery ratings and sentiment analysis was also performed on the identified sub-themes. Regression results revealed that hygiene and pricing (delivery subthemes) demonstrated lower delivery ratings. These variables can be established as indicators for restaurants and related online food delivery services to build their business model around them. Similarly, negative sentiments were observed in pricing and hygiene sub-themes. Restaurants and online food services can enhance hygiene levels of their food delivery process in order to receive higher delivery ratings. Similarly, pricing of food items can be modified such that customers are not deterred from ordering the items—food and ordering service do not become cost-prohibitive. This study devised a standardized methodology for analysing vast amounts of online user-generated content (UGC). Findings from this study can be extrapolated to other sectors and service industries such as, tourism, cleaning, transportation, hospitals and engineering especially during the pandemic.     

Differentiated goods in a dynamic Cournot duopoly with emission charges on output

We extend the dynamic Cournot duopoly framework with emission charges on output by Mamada and Perrings (Econ Anal Policy 66:370–380, 2020), which encompassed homogeneous products in its original formulation, to the more general case of differentiated goods, in order to highlight the richness in its static and dynamic outcomes. Each firm is taxed proportionally to its own emission only and charge functions are quadratic. Moreover, due to an adjustment capacity constraint, firms partially modify their output level toward the best response. Like in Mamada and Perrings (Econ Anal Policy 66:370–380, 2020), the only steady state coincides with the Nash equilibrium, and it will be considered admissible when it guarantees the positivity of the marginal emission charge. We find that the full efficacy of the environmental policy, which applies to an equilibrium that is globally asymptotically stable anytime it is admissible, is achieved in the case of independent goods, as well as with a low good interdependence degree in absolute value, independently of being substitutes or complements. When goods are substitutes and their interdependence degree is high, the considered environmental policy is still able to reduce pollution at the equilibrium, but the latter is stable just when the policy intensity degree is large enough. When instead goods are complements and their interdependence degree is high in absolute value, the considered environmental policy produces detrimental effects on the pollution level and the unique equilibrium is always unstable, when admissible. This highlights that, from the static viewpoint, even in the absence of free riding possibilities, the choice of the mechanism to implement has to be carefully pondered, according to the features of the considered economy.

     

Heckscher-Ohlin Theory or the Modern Trade Theory: How the Overall Trade Characterizes at the Global Level?

This paper has two objectives: to locate the global trade pattern and to compute the export potential of world economies. Considering the maximum number of countries and maintaining a good representative sample of the overall international trade, an empirical examination is conducted by utilizing the trade complementary index and the per-capita income variable in the standard gravity model. The main aim is to determine which of the two theoretical frameworks―either the Heckscher-Ohlin theory, which is based on factor endowments or the Modern Trade theory of Krugman-Helpman and Linder, based on the intra-industry trade―is explaining the overall global trade flows. The estimated results support the factor endowments trade theory. In other words, the observed trade patterns conform to the Heckscher-Ohlin theory of trade over intra-industry Modern trade theories. The inference drawn is based on the significantly positive coefficient of the trade complementarity index and the absolute differenced PCI variable. Furthermore, as far as export potential is concerned, there exists a vast scope for the export potential across economies. These countries can exploit the existing export potential through trade cooperation and integration at the regional and the bilateral level.

     

Electricity Tariff Changes and Consumer Sentiment on Household Consumption Expenditure in Malaysia

Purpose

This study investigates the impact of the current electricity tariff, represented by optimized tariff calculation, on Malaysian household’s consumption across different levels of income.

Design/methodology/approach

The input-output (IO) model has vastly been used in many energy economics literature that presented the matrix of production between various sectors in an economy. This study aggregated the 124 subsectors in IO Price Table 2015 into 12 groups of consumption of goods and services based on Household Expenditure Survey 2019 (HES 2019) to meet the study’ objectives.

Findings

This study found that in all simulations, high-income earners would be highly affected by the tariff changes. The lower the increment level in electricity tariff rate, the lower the magnitude would be on the changes of household expenditure level.

Research limitations/implications

Optimization in electricity tariff consumptions can pattern the Malaysian household’s consumption across different levels of income efficiently.

Practical implications

Useful to all consumer in the Malaysia economic business sector to predict their energy consumption up to optimum level.

Social implications

The study’s findings can benefit the society in optimiza their electricity consumption since everyone requires the energy for basic needs in their life.
