The Empirical Analysis

This paper examines the recent advances in stochastic frontier (SF) models and its implications for the performance of Norwegian crop-producing farms. In contrast to the previous studies, we used a cost function in multiple input-output frameworks to estimate both long-run (persistent) and short-run (transient) inefficiency. The empirical analysis is based on unbalanced farm-level panel data for 1991–2013 with 3 885 observations from 455 Norwegian farms specialising in crop production. We estimated seven SF panel data models grouped into four categories regarding the assumptions used to the nature of inefficiency. The estimated cost efficiency scores varied from 53–95%, showing that the results are sensitive to how the inefficiency is modeled and interpreted.

Main Determinants

The paper aims to assess whether financial market stress is associated with real house prices in the euro area. Building on the theory of house prices fundamentals, we first apply the second generation cointegration tests and reject a stable long-run relationship between house prices and the variables identified in the theory as their main determinants (fundamentals). Short-run panel data models are then estimated, relating real house prices to their fundamentals and the financial market stress. The results imply that the growths in the real GPD per capita and the loans to households for house purchase are the main determinants of real house prices growth in the short run. Financial market stress is significantly associated with real house prices changes only in some euro area countries. Different panel data estimators are used to show that heterogeneity and cross-section dependence needs to be accounted for to obtain robust estimates. The differences between two groups of euro area countries (the PIIGS and the non-PIIGS euro area) are also compared.

Accounting for heterogeneity in the measurement of farm efficiency is crucial to avoid biases related to climate and soil quality diversity in a given area. Therefore, this paper investigates the level of technical efficiency (TE) of Polish crop farms based on several stochastic frontier panel data models with different approaches to the measurement of unobserved heterogeneity, short- and long- run inefficiency. In our study, we show that ignoring farm heterogeneity can lead to underestimation of the level of TE in conventional stochastic frontier panel data models. Moreover, we have found empirically that not accounting for heterogeneity in the Generalized True Random Effects model may lead to incorrect estimates of persistent TE. The obtained results for Polish crop farms indicate that the level of transient TE (0.81) is lower than the level of persistent TE (0.88). This result suggests that Polish farms may have, for example, problems with adopting new technologies and poor managerial skills.

The Empirical Analysis

Even though remittances constitute the second-largest source of foreign exchange for Nigeria, with a $24 billion inflow in 2018, its impact on economic growth remains unclear. This study, therefore, examined the short-run and long-run impact of remittances on the economic growth of Nigeria using the vector error correction model. Utilizing World Bank data covering 1990–2018, the empirical analysis revealed that remittances hurt economic growth in the short run while having no impact on economic growth in the long run. Our parameter estimates indicate that a 1% increase in remittances would result in a 0.9% decrease in the gross domestic product growth rate in the short run. One policy implication of this study is that Nigeria needs to devise policies and interventions that minimize the emigration of skilled professionals rather than depending on remittances that do not offset the losses to the economy due to brain drain.

In emerging labour market, particularly, the direct and indirect association between employment level and foreign direct investment (FDI) in a dynamic economy is non-deniable. Like private and public investments, FDI promotes employment generating agenda and at the same time, sound employment scenario of an economy attracts FDI to inflow. Under this backdrop, the present study attempts to examine whether employment and net FDI inflow have long-run associations and short-run dynamics in South Asian economies for the period 1991–2016. Applying cointegration and Granger causality tests for individual country level and panel cointegration, vector error correction and Wald test on the two standardized variables—employment–population ratio and per capita net FDI inflow—reveal that the two indicators have cointegrating relations for Bangladesh and Nepal and FDI makes a cause to employment generation in Bangladesh only. Further, the panel data exercise shows the existence of long-run or equilibrium relations linking the two indicators without significant error correction results. The Wald test results show that there is short-run causality working from employment ratio to per capita FDI and vice versa. The study, thus, prescribes for ensuring quality environment in the concerned domestic economies of the region so that employment opportunities invite FDI inflow to their territories.

This study analyzed the asymmetric effects of financial development on economic growth using a model augmented with inflation and government expenditure asymmetries to inform model specification. The research question used entails, Do their asymmetry changes significantly influence growth? Using the nonlinear auto-regressive distributive lag (NARDL), the most significant results posit that positive shocks in financial development in the short run and its negative shocks in the long run increase and decrease economic growth, respectively. Regarding inflation, its positive (negative) shocks in both runs, respectively, reduce (increase) economic growth. In comparison, positive shocks in financial development that spur growth in the short run and negative shocks in financial development (government expenditure) that increase (reduce) growth are the most domineering effects as the rest of the shocks insignificantly affect growth. Results clearly demonstrate to an environment steered by stable and sustainable inflation that regulated government expenditure and comprehensive financial system deepening would positively cause economic growth. Therefore, appropriate policies that favor low inflation and reduced government spending, expansion of feasibly reformed financial institutions, capital accumulation, and increased resource mobilization should be instituted if real growth is to positively happen.

The Empirical Analysis

Taking into account the three-sector general equilibrium perspective of the government, business, and household sectors and taking government public goods investment as intermediary; this article builds mathematical models of local governmental competition and three-sector consumption. It also theoretically analyzes the impacting path of local governmental competition, causing increased investment in public goods, thereby reducing consumption. At the same time, based on the model of China's provincial panel data from 1993 to 2015, the empirical analysis shows that a 1% increase in the level of competition among local governments will result in a corresponding decrease of 0.757% in total consumption, 0.348% in governmental competition, 0.340% in business consumption and 0.366% in household consumption. Local governmental competition leads to the government's tendency to invest in public goods and reduces the regional consumption, which especially damages the consumption capacity of the household sector.
