This book gives an up to date reference on the state of the art in this highly important methodological area, which is central both to theoretical models of party competition and to empirical accounts, whether these are case studies or comparative analyses. It looks at subjects including tracking estimates of public opinion and party policy intentions in Britain and the USA; the policy space of party manifestos; and party platforms and voters' perceptions. Its panel of respected contributors reviews the refinements which have been made to established techniques as well as considering the potential and early successes of computer coding.

Michael Laver examines how the giving of exotic gifts in early modern Japan facilitated Dutch trade by ascribing legitimacy to the shogunal government and by playing into the shogun's desire to create a worldview centered on a Japanese tributary state. The book reveals how formal and informal gift exchange also created a smooth working relationship between the Dutch and the Japanese bureaucracy, allowing the politically charged issue of foreign trade to proceed relatively uninterrupted for over two centuries. Based mainly on Dutch diaries and official Dutch East India Company records, as well as exhaustive secondary research conducted in Dutch, English, and Japanese, this new study fills an important gap in our knowledge of European-Japanese relations. It will also be of great interest to anyone studying the history of material culture and cross-cultural relations in a global context.

Although Japan had severely curtailed its political involvement with the wider world in the seventeenth century, the Japanese economic influence on Asia remained quite pronounced. Even when the Japanese government expelled the Spanish and Portuguese and limited the Dutch to a small outpost in Nagasaki, and also decided to prohibit its own citizens from traveling abroad, the Japanese economy remained a force in Asia and played a significant role in the world economy as well. The seventeenth-century economy of Japan, however, was an "economy by proxy" since the agents that exchanged Asian and European luxury goods for Japanese products and precious metals were not Japanese but rather Dutch, Chinese, Korean, and Ryukyu Islanders. These peoples moved in to fill the economic gap left by the forced exclusion of the native Japanese merchants from an active role in the foreign economy of Japan. This eloquently detailed account illuminates the tremendous impact that the Japanese economy had on Asia and on the foreigners trading in Japan in the seventeenth century. This is a valuable addition to all collections in Asian Studies and World History.

A new and wide-ranging empirical overview of party policy in 47 modern democracies, including all of the new democracies of Eastern Europe.

It updates and radically extends Policy and Party Competition (1992), which established itself as a key mainstream data source for all political scientists exploring the policy positions of political parties.

This essential text is divided into three clear parts:

Part I introduces the study, themes and methodology

Part II deals in depth with the wide range of issues involved in estimating and analyzing the policy positions of key political actors.

Part III is the key data section that identifies key policy dimensions across the 47 countries, detailing their party positions and median legislators, and is complemented by graphical representations of each party system.

This book is an invaluable reference for all political scientists, particularly those interested in party policy and comparative politics.

"Policy and Party Competition "(1992) established itself as one of the mainstream data sources used by political scientists, when exploring the policy positions of political parties and has become a standard data resource for comparative political science.
This new book updates and radically extends this work, providing a wide-ranging empirical overview of party policy in 47 modern democracies, including all of the new democracies of Eastern Europe. The book is divided into three parts:
- Part I introduces the study, themes and methodology

- Part II contains a set of substantive chapters dealing in depth with the wide range of issues involved in the estimating and analyzing the policy positions of key political actors.

- Part III is the data section identifying the key policy dimensions in each of the 47 countries, party positions and median legislators on each of these, and a two-dimensional representation of each party system.
This book will prove to be an invaluable reference for all political scientists, particularly those interested in party policy and comparative politics.

Parliamentary democracy involves a never-ending cycle of elections, government formations, and the need for governments to survive in potentially hostile environments. These conditions require members of any government to make decisions on a large number of issues, some of which sharply divide them. Officials resolve these divisions by 'logrolling'- conceding on issues they care less about, in exchange for reciprocal concessions on issues to which they attach more importance. Though realistically modeling this 'governance cycle' is beyond the scope of traditional formal analysis, this book attacks the problem computationally in two ways. Firstly, it models the behavior of "functionally rational" senior politicians who use informal decision heuristics to navigate their complex high stakes setting. Secondly, by applying computational methods to traditional game theory, it uses artificial intelligence to model how hyper-rational politicians might find strategies that are close to optimal.

Making and Breaking Governments offers a theoretical argument about how parliamentary parties form governments, deriving from the political and social context of such government formation its generic sequential process. Based on their policy preferences, and their beliefs about what policies will be forthcoming from different conceivable governments, parties behave strategically in the game in which government portfolios are allocated. The authors construct a mathematical model of allocation of ministerial portfolios, formulated as a noncooperative game, and derive equilibria. They also derive a number of empirical hypotheses about outcomes of this game, which they then test with data drawn from most of the postwar European parliamentary democracies. The book concludes with a number of observations about departmentalistic tendencies and centripetal forces in parliamentary regimes.

Social interactions are rich, complex, and dynamic. One way to understand these is to model interactions that fascinate us. Some of the more realistic and powerful models are computer simulations. Simple, elegant and powerful, tools are available in user-friendly free software to help you design, build and run your own models of social interactions that intrigue you, and do this on the most basic laptop computer. Focusing on a well-known model of housing segregation, this Element is about how to unleash that power, setting out the fundamentals of what is now known as 'agent based modeling'.

Building on the Cambridge Element Agent Based Models of Social Life: Fundamentals (Cambridge, 2020), we move on to the next level. We do this by building agent based models of polarization and ethnocentrism. In the process, we develop: stochastic models, which add a crucial element of uncertainty to human interaction; models of human interactions structured by social networks; and 'evolutionary' models in which agents using more effective decision rules are more likely to survive and prosper than others. The aim is to leave readers with an effective toolkit for building, running and analyzing agent based modes of social interaction.

One of the key constitutional features of a parliamentary democracy is that the political executive, or cabinet, derives its mandate from - and is politically responsible to - the legislature. What makes a parliamentary democracy democratic is that, once a legislative election has been held, the new legislature has the power to dismiss the incumbent executive and replace it with a new one. Moreover, it sits essentially as a court, passing continual judgement on the record of the executive, and continuous sentence on its future prospects. That is how citizens, indirectly, choose and control their government. But the relationship between legislature and executive is not one-sided. The executive typically has the authority to recommend dissolution of parliament and is usually drawn from the parliament. Executive personnel, therefore, have intimate familiarity with parliamentary practices; and for their part, parliamentary personnel aspire to executive appointments. Surprisingly little is known about the constitutional relationship between legislature and executive in parliamentary regimes; the present volume seeks to remedy this.

With a total population of some 500 million, the unified countries of modern Europe constitute the world's largest collection of successful capitalist democracies. Yet within it, there are distinct clusters of states, each with its own characteristics, historical allegiances and political processes.Combining superb scholarship and rigorous empirical data with an accessible and engaging writing style, Representative Government in Modern Europe remains the leading textbook on comparativeEuropean politics. The fifth edition reflects key events and changes including the impact of the world financial and economic crisis; the EU's adoption of the Lisbon Treaty; and the election of a centre-right governments in Germany and the UK. Retaining its comprehensive thematic approach to Europe as an integrated whole, while reflecting the continued importance of the EU, the new edition explores the key themes emerging in European politics: the importance of political leadership, the rise of the populist and extreme right, the personalisation of politics, ethnicity, citizen participation.

Making and Breaking Governments offers a theoretical argument about how parliamentary democracy works. The authors formulate a theoretical model of how parties create new governments and either maintain them in office or, after a resignation or no-confidence vote, replace them. The theory involves strategic interaction, derives consequences, formulates empirical hypotheses on the basis of these, and tests the hypotheses with data drawn from the postwar European experience with parliamentary democracy.

Private Desires, Political Action is an accessible overview of one of the most important approaches to the study of politics in the modern world - rational choice theory. Michael Laver does not set out to review this entire field, but rather to discuss how we might use rational choice theory to analyze the political competition that affects almost every aspect of our lives. The broad-ranging scope of the book introduces the theory at many levels of analysis, including: the private desires of individuals; the social context of how people fulfil their desires; and the problems of collective action. The discussion of these problems extends into the arena of politics, where the activities of `political entrepreneurs' or politicians and the formation of political parties and coalitions are addressed.

Party competition for votes in free and fair elections involves complex interactions by multiple actors in political landscapes that are continuously evolving, yet classical theoretical approaches to the subject leave many important questions unanswered. Here Michael Laver and Ernest Sergenti offer the first comprehensive treatment of party competition using the computational techniques of agent-based modeling. This exciting new technology enables researchers to model competition between several different political parties for the support of voters with widely varying preferences on many different issues. Laver and Sergenti model party competition as a true dynamic process in which political parties rise and fall, a process where different politicians attack the same political problem in very different ways, and where today's political actors, lacking perfect information about the potential consequences of their choices, must constantly adapt their behavior to yesterday's political outcomes.

"Party Competition" shows how agent-based modeling can be used to accurately reflect how political systems really work. It demonstrates that politicians who are satisfied with relatively modest vote shares often do better at winning votes than rivals who search ceaselessly for higher shares of the vote. It reveals that politicians who pay close attention to their personal preferences when setting party policy often have more success than opponents who focus solely on the preferences of voters, that some politicians have idiosyncratic "valence" advantages that enhance their electability--and much more.
