This paper analyzes the linear and non-linear relationship between non-performing loans bank profitability measured by Net Interest Margin for a sample of 74 Middle Eastern North African banks over period 2005–2020. We used System Generalized Method Moments (SGMM) as approach Panel Smooth Transition Regression (PSTR) model approach. The empirical results SGMM indicated that ratio NPLs negativel...

We study the Cauchy problem for Euler-Poisson-Darboux equation, with a power nonlinearity:utt−uxx+μtut=tα|u|p,t>t0,x∈R, where μ>0, p>1 and α>−2. Here either t0=0 (singular problem) or t0>0 (regular problem). show that this model may be interpreted as semilinear wave equation borderline dissipation: existence of global small data solutions depends not only on p, but also parameter μ. Global weak...

This study analyses the nonlinear dynamic impact of economic development on income inequality in a prudential policy regime panel 15 emerging markets from 1985–2019. More importantly, we seek to extend existing debate this subject, with roots back seminal work by Kuznets and many others, add twist introducing distinction between (1985–1999) non-prudential (2000–2019), as well threshold level at...

We use a sample of 40 developing and emerging countries over the period 1995–2015 to assess effectiveness international reserve holding as crisis mitigator. test relevance accumulation decreasing returns assumption by estimating most recent version PSTR model. find that increasing stocks reserves allows domestic authorities mitigate negative impacts financial banking vulnerabilities on GDP grow...

BACKGROUND The association between peritoneal solute transport rates (PSTRs) and inflammatory markers in patients on peritoneal dialysis (PD) is still under investigation. We aimed to elucidate their relationship during the first year on PD. METHODS We performed a prospective observational study with 187 incident PD patients who were treated with either biocompatible solution (BCS) or convent...

This paper aims to evaluate the impact of commodity terms trade (CTOT) shocks on labour market resilience Sub-Saharan Africa (SSA) countries, comparing franc zone countries one hand, from non-franc other hand. The results PVAR estimation indicate a positive in SSA countries. finding holds both and When robustness is checked through PSTR, this relationship established be non-linear. policy impli...

Cytokine profiles in peritoneal dialysis effluent (PDE) vary among patients of continuous ambulatory peritoneal dialysis (CAPD), which may indicate the therapeutic efficiency of CAPD. We examined the cytokine profiles of PDE with stable CAPD and analyzed their relation with the peritoneal solute transport rate (PSTR). The peritoneal equilibration test (PET) was performed to evaluate peritoneal ...

This paper analyzes the effects of trade openness on economic growth in a panel thirty developed and developing countries. The fixed model was estimated using PSTR technique data covering period 1980-2019. results show that relationship between is non-linear, external depend thresholds national income per capita. Below threshold 35 118 USD capita, has no significant effect growth. Above this th...

Based on the panel data of 35 OECD countries from 2001 to 2019, this paper empirically analyzes nonlinear effect exchange rate economic growth through PSTR model. The results show that appreciation has a certain role in promoting growth. When value local currency is high, stronger growth; when low, weaker Further research shows development export trade strong positive impact growth, while inflo...
