This paper develops a model based on Schumpeter's process of creative destruction. It departs from existing models of endogenous growth in emphasizing obsolescence of old technologies induced by the accumulation of knowledge and the resulting process or industrial innovations. This has both positive and normative implications for growth. In positive terms, the prospect of a high level of research in the future can deter research today by threatening the fruits of that research with rapid obsolescence. In normative terms, obsolescence creates a negative externality from innovations, and hence a tendency for laissez-faire economies to generate too many innovations, i.e too much growth. This "business-stealing" effect is partly compensated by the fact that innovations tend to be too small under laissez-faire. The model possesses a unique balanced growth equilibrium in which the log of GNP follows a random walk with drift. The size of the drift is the average growth rate of the economy and it is endogenous to the model ; in particular it depends on the size and likelihood of innovations resulting from research and also on the degree of market power available to an innovator.

Since the pioneering work of Donald and his first Lancet paper in 1958, the use of ultrasound in obstetrics and gynaecology has evolved rap idly. The introduction of grey scale techniques enhanced our ability to identify different tissues on the basis of their texture. However, it was the introduction of the linear array real-time scanner in the mid seven ties that changed ultrasound from being an "eccentric art form" to a readily available and usable technique. This led to the first reports of the diagnosis of neural tube defects using ultrasound by Campbell, as well as the establishment of fetal biometry. In the midst of this activity the parallel development of the transvaginal probe by Kratochwill went almost unnoticed by most gynaecologists. Yet the application of this technique has since had a major impact on many areas of gyna ecological practice, and on infertility in particular. Since the demon stration of transvaginal follicle aspiration, the vaginal route has become standard for most invasive ultrasound guided gynaecological procedures. The relatively new technical advance of transvaginal colour Doppler may potentially have just as great an impact. The introduction and use of transvaginal colour flow imaging has facili tated the study of vascular changes within the pelvis.

In 1517, Martin Luther nailed his 95 theses to the wall of Wittenberg church. He argued that the Church’s internally consistent but absurd doctrines had pickled into a dogmatic structure of untruth. It was time for a Reformation. Half a millennium later, Steve Keen argues that economics needs its own Reformation. In Debunking Economics, he eviscerated an intellectual church – neoclassical economics – that systematically ignores its own empirical untruths and logical fallacies, and yet is still mysteriously worshipped by its scholarly high priests. In this book, he presents his Reformation: a New Economics, which tackles serious issues that today's economic priesthood ignores, such as money, energy and ecological sustainability. It gives us hope that we can save our economies from collapse and the planet from ecological catastrophe. Performing this task with his usual panache and wit, Steve Keen’s new book is unmissable to anyone who has noticed that the economics Emperor is naked and would like him to put on some clothes.

New firm formation is a critical driver of job creation, and an important contributor to the responsiveness of the economy to aggregate shocks. In this paper we examine the characteristics of the individuals who become entrepreneurs when local opportunities arise due to an increase in local demand. We identify local demand shocks by linking fluctuations in global commodity prices to municipality level agricultural endowments in Brazil. We find that the firm creation response is almost entirely driven by young and skilled individuals, as measured by their level of experience, education, and past occupations involving creativity, problem-solving and managerial roles. In contrast, we find no such response within the same municipalities among skilled, yet older individuals, highlighting the importance of lifecycle considerations. These responsive individuals are younger and more skilled than the average entrepreneur in the population. The entrepreneurial response of young individuals is larger in municipalities with better access to finance, and in municipalities with more skilled human capital. These results highlight how the characteristics of the local population can have a significant impact on the entrepreneurial responsiveness of the economy.

We test the effect of foreign direct investment (FDI) on economic growth in a cross-country regression framework, utilizing data on FDI flows from industrial countries to 69 developing countries over the last two decades. Our results suggest that FDI is an important vehicle for the transfer of technology, contributing relatively more to growth than domestic investment. However, the higher productivity of FDI holds only when the host country has a minimum threshold stock of human capital. In addition, FDI has the effect of increasing total investment in the economy more than one for one, which suggests the predominance of complementarity effects with domestic firms.

Conventional theories of capitalism are mired in a deep crisis: after centuries of debate, they are still unable to tell us what capital is. Liberals and Marxists both think of capital as an ‘economic’ entity that they count in universal units of ‘utils’ or ‘abstract labour’, respectively. But these units are totally fictitious. Nobody has ever been able to observe or measure them, and for a good reason: they don’t exist. Since liberalism and Marxism depend on these non-existing units, their theories hang in suspension. They cannot explain the process that matters most – the accumulation of capital. This book offers a radical alternative. According to the authors, capital is not a narrow economic entity, but a symbolic quantification of power. It has little to do with utility or abstract labour, and it extends far beyond machines and production lines. Capital, the authors claim, represents the organized power of dominant capital groups to reshape – or creorder – their society. Written in simple language, accessible to lay readers and experts alike, the book develops a novel political economy. It takes the reader through the history, assumptions and limitations of mainstream economics and its associated theories of politics. It examines the evolution of Marxist thinking on accumulation and the state. And it articulates an innovative theory of ‘capital as power’ and a new history of the ‘capitalist mode of power’.

Abstract: We quantify the macroeconomic effects of COVID-19 for a small open economy by calibrating a SIR-multi-sector-macro model to Turkey. Sectoral supply shocks are based on the proximity requirements in each sector and the ability to work from home. Physical proximity determines the supply shock through its effect on infection rates. Sectoral demand shocks incorporate domestic and foreign demand, both of which adjust with infection rates. We calibrate demand shocks during COVID-19 using real-time credit card purchase data. Our results show that the optimal policy, which yields the lowest economic cost and saves the maximum number of lives, can be achieved under a full lockdown of 39 days. Economic costs are much larger for an open economy as the shocks are amplified through the international production network. A decline in foreign demand leads to losses in domestic sectors through international input-output linkages, accounting for a third of the total output loss. In addition, the reduction in capital flows deprives the network from its trade financing needs, where sectors with larger external finance needs experience larger losses. The policy options are limited given sparse fiscal resources to fight the pandemic domestically, while serving the external debt. We present historical evidence from 2001 crisis of Turkey, when fiscal, monetary and exchange rate policies were employed altogether to deal with a triple crisis of balance of payments, banking, and sovereign debt

The book provides a comprehensive overview of the latest econometric methods for studying the dynamics of macroeconomic and financial time series. It examines alternative methodological approaches and concepts, including quantile spectra and co-spectra, and explores topics such as non-linear and non-stationary behavior, stochastic volatility models, and the econometrics of commodity markets and globalization. Furthermore, it demonstrates the application of recent techniques in various fields: in the frequency domain, in the analysis of persistent dynamics, in the estimation of state space models and new classes of volatility models. The book is divided into two parts: The first part applies econometrics to the field of macroeconomics, discussing trend/cycle decomposition, growth analysis, monetary policy and international trade. The second part applies econometrics to a wide range of topics in financial economics, including price dynamics in equity, commodity and foreign exchange markets and portfolio analysis. The book is essential reading for scholars, students, and practitioners in government and financial institutions interested in applying recent econometric time series methods to financial and economic data.

Rigorous nonpartisan research on the effects of economic forces and public policy on entrepreneurship and innovation. Entrepreneurship and innovation are widely recognized as drivers of economic dynamics and long-term prosperity. This series communicates key findings about the implications of entrepreneurial and innovative activity across the economy. Entrepreneurship and Innovation Policy and the Economy, Volume 3, synthesizes key findings about entrepreneurial and innovative activity in the U.S. economy, conveying insights on contemporary challenges and providing an analytical base for policy design. In the first paper, Jorge Guzman, Fiona Murray, Scott Stern, and Heidi Williams examine regional innovation engines and highlight the place-specific actions, potential bottlenecks, and roles of different stakeholders in catalyzing entrepreneurship and innovation. Next, Lee Branstetter and Guangwei Li examine the challenges faced by the Chinese central government in implementing industrial policy to push the technology frontier while local governments and businesses deploy resources to advance their own, not necessarily aligned, interests. Turning to climate issues, James Sallee analyzes policies aimed at accelerating the energy transition by hastening the replacement of durable capital assets like automobiles and residential appliances that last for decades and slow the adoption of cleaner technologies. Joshua Gans studies cryptocurrencies and other crypto-token-based instruments and the broad range of government responses to them, particularly in the U.S. Finally, Ina Ganguli and Fabian Waldinger consider the effects of the Russian invasion of Ukraine on the human capital in the Ukrainian science community.

This paper provides estimates of output multipliers for spending in clean energy and biodiversity conservation, as well as for spending on non-ecofriendly energy and land use activities. Using a new international dataset, we find that every dollar spent on key carbon-neutral or carbon-sink activities can generate more than a dollar’s worth of economic activity. Although not all green and non-ecofriendly expenditures in the dataset are strictly comparable due to data limitations, estimated multipliers associated with spending on renewable and fossil fuel energy investment are comparable, and the former (1.1-1.5) are larger than the latter (0.5-0.6) with over 90 percent probability. These findings survive several robustness checks and lend support to bottom-up analyses arguing that stabilizing climate and reversing biodiversity loss are not at odds with continuing economic advances.
