Partial Regulation in Vertically Differentiated Industries

We provide theoretical foundations for quality‐adjusted price‐cap regulation in industries where a regulated incumbent and an unregulated entrant offer vertically differentiated products competing in price and quality. We show that, whether or not the incumbent anticipates the reaction of the entrant, the optimal weights in the cap depend upon the market served by the entrant, despite the latter not being directly concerned by regulation. We further show that the cap is robust to small errors in the weights. Our findings point to the conclusion that, in partially regulated industries, regulators should use information about the whole sectors rather than on the sole regulated incumbents.     

Depression dynamics: a new estimate of the Anglo‐American manufacturing productivity gap in the interwar period1

During the interwar period the manufacturing productivity gap between the US and the UK became much larger than existing estimates suggest. In this article a new comparison of US/UK productivity levels for 1935 is presented, utilizing a more rigorous methodology to revise the widely used, but methodologically outdated, benchmark comparison by Rostas that was published in 1948. Secondly, the comparison is extended to take account of variations in input prices, and it is shown that double deflation has a substantial effect on the new benchmark, particularly at the industry level. Thirdly, labour input is adjusted for actual hours worked. US manufacturing displayed a much higher level of comparative productivity for the key industries of the second industrial revolution, such as chemicals and engineering. These results support revisionist accounts of the depression's strengthening of US productivity leadership.     

The rise and fall of Spain (1270–1850)1

Two distinctive regimes are distinguished in Spain over half a millennium. The first one (1270s–1590s) corresponds to a high land–labour ratio frontier economy, which is pastoral, trade‐oriented, and led by towns. Wages and food consumption were relatively high. Sustained per capita growth occurred from the end of the Reconquest (1264) to the Black Death (1340s) and resumed from the 1390s only broken by late fifteenth‐century turmoil. A second regime (1600s–1810s) corresponds to a more agricultural and densely populated low‐wage economy which, although it grew at a pace similar to that of 1270–1600, remained at a lower level. Contrary to pre‐industrial western Europe, Spain achieved its highest living standards in the 1340s, not by mid‐fifteenth century. Although its death toll was lower, the plague had a more damaging impact on Spain and, far from releasing non‐existent demographic pressure, destroyed the equilibrium between scarce population and abundant resources. Pre‐1350 per capita income was reached by the late sixteenth century but only exceeded after 1820.     

Do Consumers Care about Ethics? Willingness to Pay for Fair‐Trade Coffee

Consumers’ buying behavior is not consistent with their positive attitude toward ethical products. In a survey of 808 Belgian respondents, the actual willingness to pay for fair‐trade coffee was measured. It was found that the average price premium that the consumers were willing to pay for a fair‐trade label was 10%. Ten percent of the sample was prepared to pay the current price premium of 27% in Belgium. Fair‐trade lovers (11%) were more idealistic, aged between 31 and 44 years and less “conventional.” Fair‐trade likers (40%) were more idealistic but sociodemographically not significantly different from the average consumer.     

Central Bank Policy Paths and Market Forward Rates: A Simple Model

Increasingly many central banks announce likely paths for future policy rates. Recent experience suggests that market forward rates can differ substantially from those announced. Models commonly adopted in policy analysis ignore such differences. This paper studies a simple model that can capture deviations between announced paths and market forward rates. We detail the macroeconomic transmission of such deviations and show how the model can inform policy deliberations.     

环保约谈能否促进企业绿色投资

环保约谈制度是提高环境治理水平所实行的环境执法监督新方式,对于破解环境治理难题,提高环境治理绩效至关重要。本文利用环保约谈所产生的准自然实验变化,以2013—2019年我国重污染行业上市公司为研究样本,考察环保约谈对企业绿色投资的影响。双重差分法的检验结果表明：在环保约谈所涉及城市的上市公司中,环保约谈促进了企业绿色投资。在此基础上,进一步检验发现,环保约谈对绿色投资的促进效果较为明显的企业主要来自于全要素生产率较高,行业市场竞争程度低及融资约束低的企业。研究结论从企业加强环保绿色投资决策的角度为环保约谈的经济后果提供了微观的证据,这不仅对于我们了解环保约谈这一政策对微观主体企业的影响效应具有一定意义,同时,对国家在经济发展中,如何实施更好的环境治理政策具有一定的指导意义。
