We employ an empirical approach to analyse the data and complement the empirical findings with a theoretical framework. The results suggest a negative impact of BOT adoption on the employment of low-skilled workers, while skilled workers experience minimal effects. Interestingly, the study also finds a reduction in the wage gap between skilled and unskilled labour. A General Equilibrium framework underpins the theoretical explanation for these empirical observations. The model highlights the presence of a talent gap within the low skilled labourers within the manufacturing sector despite the continued demand for low-skilled labour. This gap impedes employment growth for low-skilled workers, even as their wages potentially increase. Thus, increased robot utilization may lead to higher wages but lower employment of the low skilled labourers within the industrial sector. Additionally, the paper incorporates secondary evidence from anecdotal surveys to bolster the research conclusions.</p>","PeriodicalId":42219,"journal":{"name":"JOURNAL OF QUANTITATIVE ECONOMICS","volume":"27 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141738582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Knowledge of these linkages is extremely important in creating renewable energy policies and accomplishing targets, as India chose an ambitious goal of 500 GW of renewable energy capacity (including 73 GW from hydro) by 2030. The findings reveal that although hydropower consumption and economic expansion contribute to reducing the ecological footprint, fossil fuel consumption accelerates environmental degradation. We find evidence of a long-run asymmetry relationship between hydropower consumption and ecological footprint.

In this paper we test the sustainability of Portuguese fiscal policy during this most recent period of Portuguese history – a time when the principle of sound finance is no longer proclaimed as a dogma. Using data taken from different sources, we conclude that, although Portugal has experienced very troubled periods throughout its Democracy, fiscal policy was sustainable during 1974–2020. This sustainability was, however, weak. Our conclusion is based on a difference stationary public debt ratio, on a stationary budget deficit as a percentage of GDP, and, also on the existence of a long-term relation between public revenues and expenditures ratios with a reduced cointegration coefficients.

This assumption allows one to utilize the link between the total variable cost and total revenue implied by profit maximization to recover the CES preference parameter. This paper explores the robustness of the constant MC assumption in Monte Carlo experiments, where the control group consists of simulated constant MC firms and the treatment group involves different degrees of violation of the assumption. The results of our experiments show that the constant MC assumption indeed has a high identification power. Nevertheless, researchers need to ensure that their samples contain a sufficient proportion of constant MC firms, which, in our experiments, must be around 20 percent. We also find that, irrespective of the actual proportion of constant MC firms in the sample, the constant MC assumption correctly identifies the CES preference parameter if the elasticity of substitution within the industry is 2.5 or lower.</p>","PeriodicalId":42219,"journal":{"name":"JOURNAL OF QUANTITATIVE ECONOMICS","volume":"51 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141196309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A percentage point increase in the weighted average overnight call money rate (WACR) is, on an average, associated with 36–37 basis points rise in g-sec yield, whereas a percentage point fall in WACR leads to decrease in g-sec yield by 29–30 basis points. In the short-run, the asymmetric impact of WACR on the g-sec yield, though less conclusive, ranges between 18 and 20 basis points when WACR increases and 14–18 basis points when WACR decreases.

The present study is based on time series data (i.e. from 1978 to 2014). Therefore, in the energy function, a dummy variable has also been included, which represents the possibility of the series discontinuity or structural break. The NARDL results reveal that the upside variations in national output (GDP) have amplified the scope of energy consumption in the long run, whereas the impact of downside variations is negative and substantial. Similarly, the study has separately captured the impact of upside and downside variations in the globalization index (i.e., economic and socio-political factors) on energy consumption in the country. It is evident from the results that improvement in these factors has intensified energy consumption in the long run, whereas the impact of decreased globalization index is found negative and significant. Further, the study confirms that the upside variation in capital formation has not significantly reduced energy utilization in the region. However, the downside movements (i.e., negative shocks in capital formation) have significantly increased the demand for energy in India. It is evident from the results that besides the increase in national output (GDP), the increase in the socio-political arena has also contributed to raising energy consumption in India. Contrarily, the downside movements in economic and socio-political factors have led to decreased energy consumption. The weak substitutability between upside movements in capital formation and energy consumption reveals that the country needs to generate energy-efficient production techniques. Based on the outcomes, it can be proposed that the government should promote research and development in all spheres of life (i.e., economic and socio-political) where energy is used as an input.</p>","PeriodicalId":42219,"journal":{"name":"JOURNAL OF QUANTITATIVE ECONOMICS","volume":"50 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2024-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140634753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
