Does Climate Change Asymmetrically Affect Rice Productivity In India? New Insight From NARDL Cointegration Approach

This article attempt to answer the question "whether the dynamic relationship between climate change and rice productivity is symmetrical or asymmetrical" using data from 1990-2017 in India. First, we test the symmetrical and long-run dynamic relationship using the Autoregressive Distributed Lags (ARDL) model and test the asymmetrical and cointegration relationship based on Nonlinear Auto-Regressive Distributed Lag (NARDL) technique. The results of the ARDL model indicates that no symmetrical relationship between the variables in long-run. Whereas outcomes of the NARDL bound test reveal that there is long-run asymmetrical impact of climate change on rice productivity. The positive and negative shock of climate change has affected the rice productivity by different magnitude in India. The Wald statistics confirm asymmetric relationship between rice productivity and climate change in the long-run while only short-run asymmetrical relationships exist between rainfall and rice productivity in India.Furthermore, dynamic multipliers indicate that negative component of rainfall and temperature has a dominant effect over the positive component on rice productivity. To the best of the author's knowledge, no studies have been done to assess both symmetrical and asymmetrical dynamic relationships between climate change and rice productivity using ARDL and NARDL cointegration approaches in India's context. This study will help frame the environmental policies and strategy to cope with climate change in India's agriculture productivity.

Structural, Evolutionary, and Functional Analysis of the Protein O-Mannosyltransferase Family in Pathogenic Fungi

Protein O-mannosyltransferases (Pmts) comprise a group of proteins that add mannoses to substrate proteins at the endoplasmic reticulum. This post-translational modification is important for the faithful transfer of nascent glycoproteins throughout the secretory pathway. Most fungi genomes encode three O-mannosyltransferases, usually named Pmt1, Pmt2, and Pmt4. In pathogenic fungi, Pmts, especially Pmt4, are key factors for virulence. Although the importance of Pmts for fungal pathogenesis is well established in a wide range of pathogens, questions remain regarding certain features of Pmts. For example, why does the single deletion of each pmt gene have an asymmetrical impact on host colonization? Here, we analyse the origin of Pmts in fungi and review the most important phenotypes associated with Pmt mutants in pathogenic fungi. Hence, we highlight the enormous relevance of these glycotransferases for fungal pathogenic development.

The Uneven Geography of Tyranny

This chapter analyses the asymmetrical impact of the central policies on states. Federal structure and geographical distance meant that the spatial reach of these policies was not uniform. The arbitrary powers of the Emergency were a stronger presence in the Hindi belt than in the South, and in the states ruled by the Congress than in the holdouts. This was due to various factors such as the strengths and weaknesses of local Congresses vis-à-vis the opposition and the party at the centre; the strategies of state elites and bureaucracies; electoral considerations; factional competition; lobby influence; and the solipsism of the regime in Delhi. These were all determinants in the spread of the geography of tyranny which, on the whole, resulted in the Emergency being felt more strongly in the capital, its neighbouring states, and the Hindi belt than in states ruled by the opposition—the North East and South India.

A tough trade-off? The asymmetrical impact of populist radical right inclusion on satisfaction with democracy and government

Abstarct Populist radical right (PRR) parties are increasingly included in coalition governments across Western Europe. How does such inclusion affect satisfaction with democracy (SWD) in these societies? While some citizens will feel democracy has grown more responsive, others will abhor the inclusion of such controversial parties. Using data from the European Social Survey (2002–2018) and panel data from the Netherlands, we investigate how nativists’ and non-nativists’ SWD depends on mainstream parties’ strategies towards PRR parties. We show that the effect is asymmetrical: at moments of inclusion nativists become substantially more satisfied with democracy, while such satisfaction among non-nativists decreases less or not at all. This pattern, which we attribute to Easton’s ‘reservoir of goodwill’, that is, a buffer of political support generated by a track-record of good performance and responsiveness, can account for the seemingly contradictory increase in SWD in many Western European countries in times of populism.

The Oil Price and Trade Nexus in the Gulf Co-Operation Council Countries

The present study investigates the asymmetrical impacts of oil prices and real exchange rates on the trade balances in the Gulf Co-operation Council countries. Using panel estimates, we found the symmetrical positive effect from the oil prices and the asymmetrical positive effect from the real exchange rates on the trade balances. For country-specific results, increasing oil prices showed a positive effect on the trade balances in Oman, Saudi Arabia, and the UAE and a negative effect in Kuwait. Decreasing oil prices carried a positive relationship with the trade balances in Bahrain, Oman, Qatar, and the UAE. The oil prices showed an asymmetrical impact on the trade balances in all countries, except Saudi Arabia. Moreover, the depreciation helped to improve the trade balances in Bahrain, Oman, Qatar, and the UAE. The appreciation worsened the trade balances in Oman, the UAE, and Saudi Arabia and improved the trade balance in Kuwait. Moreover, the asymmetrical relationships between the real exchange rates and the trade balances were corroborated in all of the investigated countries.

The Impact of Sentiment on Commodity Return and Volatility

This study empirically investigates the effect of investor sentiment on returns and volatility of eight commodities. The findings suggest that sentiment has a predictive power on these commodities’ return and volatility. Fundamentally, return and volatility are positively associated with sentiment, suggesting that investors in the commodity markets are irrational — entailing the existence of noise trading. The results confirm the prediction of the affect infusion model in which optimistic investors are willing to take more risks, thus, raising returns and volatility. Furthermore, sentiment has a significant asymmetrical impact on volatility, and negative sentiment has a significantly greater impact than positive sentiment.

Asimetris Nilai Tukar Rupiah Terhadap Harga Saham Sektor Keuangan Periode 2013-2019

This paper examines the asymmetrical effect of the rupiah exchange rate on financial sector stock prices on the Indonesian stock exchange using the Non-Linear Autregressive Distributed Lag (NARDL) method with monthly data. Estimation results show that interest rates and exchange rates affect the movement of stock prices in the financial sector, there is a long-term relationship between the exchange rate with financial sector stock prices, our results also show the asymmetrical impact of exchange rate variables on financial sector stock prices, we also find when the exchange rate is positive (appreciation ) the effect is lower than when the exchange rate is negative (depreciation). Tulisan ini meneliti tentang efek asimetris kurs rupiah terhadap harga saham sektor keuangan di bursa efek Indonesia dengan menggunakan metode Non-Linier Autregressive Distributed Lag (NARDL) dengan data bulanan. Hasil estimasi menunjukkan bahwa suku bunga dan kurs berpengaruh terhadap pergerakan harga saham sektor keuangan, terdapat hubungan jangka panjang antara kurs dengan harga saham sektor keuangan, hasil kami juga menunjukkan dampak asimetris variabel kurs terhadap harga saham sektor keuangan, kami juga menemukan ketika kurs positif (apresiasi) pengaruhnya lebih rendah dibandingkan saat kurs negative (depresiasi).

A Contribution to a European Strategy for the Well-being of Citizens in the Face of Automation

This article investigates the current and expected impact of automation technology in the well-being of European citizens. First, we explore the technical, social and economic factors that determine technological progress and the implementation of the new technologies. Second, we review the expected impact of automation on employment. Finally, we assess the impact that automation will have on the well-being of European citizens in light of the two first sections. To this end, we draw on the expected asymmetrical impact of automation in people with different education levels and on current inequality trends. Throughout the article, we use a normative approach, prescribing what European policy makers should take into account in light of our findings. We find that it is unclear what the net effect of technology on employment will be, but automation of non-routine manual and cognitive tasks will displace a significant percentage of workers. We find that current trends of increasing inequalities will intensify due to the fact that automation will affect more low-skilled workers. We find that the current institutional design of the European Union is unfit to tackle educational and social protection challenges. We can therefore expect social resistance to technological progress and political instability in the years to come.

Asymmetric Effect in the Relationship between Oil Prices and Activity: An Estimate of the VECM Model for Eight Emerging Countries

In this study, we attempt to study the impact of oil shocks on the economic activity of eight emerging countries with different importing and exporting profiles, targeting and non-targeting inflation and thus verify the hypothesis of non-linearity. To do this, we used the VECM methodology. In addition to oil prices (the linear variation and its volatility, positive and negative movements in prices), we introduced the interest rate and industrial production as a proxy variable of the activity. The result shows that the economies of these countries are generally more sensitive to net increases in oil prices than to their volatility. Thus, the asymmetrical impact is clearly proven in the results especially in the long run. If the rise in oil prices negatively affects production, the decline does not favor its reshuffle. Indeed, if increases in oil prices reduce economic growth, their declines have no expansionary effect. In addition, the distinction between exporting and importing countries is not obvious. Furthermore, the addition of interest rates indicates that the first prefigurations indicate a tightening of interest rates by the central banks of the target and non-target countries selected in our study.
