The academic agenda for studying social media and politics has been somewhat haphazard. Thanks to rapid technological change, a cascade of policy-relevant crises, and sheer scale, we do not have a coherent framework for deciding what questions to ask. This Element articulates such a framework by taking existing literature from media economics and sociology and applying it reflexively, to both the academic agenda and to the specific case of politics on YouTube: the Supply and Demand Framework. The key mechanism, traced over the past century, is the technology of audience measurement. The YouTube audience comes pre-rationalized in the form of Likes, Views and Comments, and is thus unavoidable for all actors involved. The phenomenon of 'radicalization' is best understood as a consequence of accelerated feedback between audiences and creators, radicalizing each other. I use fifteen years of supply and demand data from YouTube to demonstrate how different types of producers respond more or less to this feedback, which in turn structures the ideological distribution of content consumed on the platform. This title is also available as Open Access on Cambridge Core.
A review of past research picking out common errors and problems and suggesting a fresh approach dealing with all news media sources, not one at a time, and avoiding speculation, plausible or otherwise. It points out how lack of information has resulted in speculation to fill the gap, some of it implausible, contradictory and highly imaginative, and it argues for a close study of how media and audiences interact to produce media effects.
Even if populism is not simply an illiberal ideology, it is bad for democracy. Because populists are not constrained by power-seeking party elites, they are more likely, on average, to erode civil liberties and judicial and legislative constraints on their authority. At the extreme, populists so erode these constraints that they cross the threshold into authoritarianism. The best defense against this democratic rollback is not to be found in policy alone. Rather, institutional changes are needed that incentivize power-seeking politicians to create and sustain bureaucratic parties. The conditions that produced the mass membership parties of the twentieth century have essentially passed. But a new generation of programmatic political organizations could sustain democracy well into the future, taking advantage of new tools to map how we live and work, integrating people across space, and forging new civil and political spaces.
Chapter 2 considers and critiques a number of rationalist explanations for these developments, including geopolitics, financial necessity, administrative capacity, principal-agent problems, and potential collective action issues. It argues, first, that some combination of these factors is largely capable of explaining the Qing’s approach to nonagricultural taxation, which grew whenever the state faced significant fiscal pressure, but was subject to a number of political economy and administrative constraints that became increasingly apparent in the nineteenth century. The chapter then argues that these rationalist theories are unable to fully explain the stagnation of agricultural taxes from the early eighteenth century to the end of the nineteenth century, which suggests that ideological factors should be brought in to complete the picture.
Microeconomics focuses on the mechanics of demand and supply and development of the argument that competitive markets achieve efficiency in the allocation of resources. The tools of microeconomics find application in macroeconomics for analyzing markets that pertain to the economy as a whole, specifically, the market for loanable funds in which the interest rate is determined and the market for foreign exchange in which the exchange rate is determined.
Markets are intersections of buyers and sellers brought together to exchange goods and services most efficiently, so the theory goes. In fact, markets are also connected to barter and exchange and to their underlying value: resourcefulness. We look at Nina Katchadourian and her artwork made on airplanes ("Seat Assignment") as an example of resourcefulness, Caroline Woolard’s Work Dress as an example of barter, and Elizabeth Cleland’s exhibition as an example of equivalencies created by markets. We introduce supply and demand, how the graphs are constructed, and how to think about shifts in supply and demand.
Chapter 2 examines Burke’s fundamental beliefs on market economies. I first provide an outline of the agricultural economy in late eighteenth-century England in order to draw a specific historical context for Burke’s economic thought during that period. Then I use Thoughts and Details to explain his commentary on market liberty. I discuss Burke’s support for a free domestic grain trade; government restraint; supply and demand laws; and the competitive price system. For Burke, the internal grain market should be largely protected from state intrusion. The silent efficiency of supply and demand laws channeled provisions to communities without requiring the hand of government. Prices of goods should be determined by the market, not by magistrates, who lacked the knowledge of local market conditions necessary to establish equitable prices and create fair labor contracts. I also investigate Burke’s firm defense of middlemen in Thoughts and Details, and describe his efforts in 1772 to repeal long-standing statutes that had banned the middlemen trading activities of forestalling, regrating, and engrossing. According to Burke, middlemen played a crucial role in the provisions trade by helping promote the smooth distribution of goods and lower prices.
This contribution takes a look back at the supply and demand model of selection and recruitment, developed by Joni Lovenduski and Pippa Norris in Political Recruitment: Gender, Race and Class in the British Parliament (1995). The core understanding of this model was that candidate selection was an interactive process in which both selectors and aspirants affected outcomes that were organized in several sets of institutions. The model illuminates power in particular institutions – British political parties – and was designed to examine the various effects of the selection process. This contribution reflects on the model and puts forward ideas and arguments about what might be done differently, taking into account the theoretical and methodological innovations of the succeeding generation of scholars who have used the model. It also identifies remaining challenges for research on candidate selection and suggests that the supply and demand model is sufficiently flexible that it can still travel across national, system and party boundaries.
This paper asks how much money Republican aristocrats could make from agriculture and approaches the question from the perspective of supply rather than demand. Potential growers of wheat, wine, and grain were so numerous in second- and first-century B.C. Italy that its urban population could not have provided a market large enough to enable each of them to derive a substantial income from meeting its demand for staple foods. Agriculture is not likely to have furnished the economic foundation for most senators' lavish life-styles. Instead, money-lending and other commercial activities were where the profits were, while prestige and similar non-economic factors guided their decisions about investments in land.
Models of the exchange process based on search theory can be used to
analyze the features of objects that make them more or less likely to
emerge as money in equilibrium. These models illustrate the
trade-off between endogenous acceptability (an equilibrium property)
and intrinsic characteristics of goods, such as storability or
recognizability. We look at how the relative
supply and demand for various goods affect their likelihood of
becoming money. Intuitively, goods in high demand and/or low supply
are more likely to appear as commodity money, subject to the
qualification that which object ends up circulating as a medium of
exchange depends at least partly on convention. Welfare properties
and fiat money are discussed.
The implications of world population growth for future fertilizer use and impact on the environment have scarcely been predicted. We investigated world protein production using a global nitrogen balance model. The model assumes that world population continues to grow and crop yield per unit area is closely related to nitrogen fertilizer use. About five times more cereal protein is needed to produce meat protein through farming. Advanced countries consume more meat than people in developing countries. Assuming the world's arable land remains constant in area in the next century, and if the meat consumption in advanced countries is matched by the rest of the world, the demand for fertilizer will increase and reach 220 Tg y-1 by the middle of the next century. This is approximately three times more fertilizer than is currently used, and would accelerate environmental deterioration. The world would be suffering from conflict between supplying sufficient protein and greater nitrogen pollution of the environment.
