Tax-benefit Model
A tax-benefit model is a form of microsimulation model. It is usually based on a representative or administrative data set and certain policy rules. These models are used to ''cost'' certain policy reforms and to determine the winners and losers of reform. One example is EUROMOD, which models taxes and benefits for 27 EU states, and its post-Brexit offshoot, UKMOD. Overview Tax-benefit models are used by policy makers and researchers to examine the effects of proposed or hypothetical policy changes on income inequality, poverty and government budget. Their primary advantage over conventional cross-country comparison method is that they are very powerful at evaluating policy changes not only ''ex post'', but also ''ex ante''. Generally, tax-benefit models can simulate income taxes, property taxes, social contributions, social assistance, income benefits and other benefits. The underlying micro-data are obtained mainly through household surveys. These data include information abo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsimulation
Microsimulation is the use of computerized analytical tools to perform analysis of activities such as highway traffic flowing through an intersection, financial transactions, or pathogens spreading disease through a population on the granularity level of individuals. Synonyms include microanalytic simulation and microscopic simulation. Microsimulation, with its emphasis on stochastic or rule-based structures, should not be confused with the similar complementary technique of multi-agent simulation, which focuses more on the behaviour of individuals. For example, a traffic microsimulation model could be used to evaluate the effectiveness of lengthening a turn lane at an intersection, and thus help decide whether it is worth spending money on actually lengthening the lane. Introduction Microsimulation can be distinguished from other types of computer modeling in looking at the interaction of individual ''units'' such as people or vehicles. Each unit is treated as an autonomous e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Set
A data set (or dataset) is a collection of data. In the case of tabular data, a data set corresponds to one or more table (database), database tables, where every column (database), column of a table represents a particular Variable (computer science), variable, and each row (database), row corresponds to a given Record (computer science), record of the data set in question. The data set lists values for each of the variables, such as for example height and weight of an object, for each member of the data set. Data sets can also consist of a collection of documents or files. In the open data discipline, a dataset is a unit used to measure the amount of information released in a public open data repository. The European data.europa.eu portal aggregates more than a million data sets. Properties Several characteristics define a data set's structure and properties. These include the number and types of the attributes or variables, and various statistical measures applicable to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reform
Reform refers to the improvement or amendment of what is wrong, corrupt, unsatisfactory, etc. The modern usage of the word emerged in the late 18th century and is believed to have originated from Christopher Wyvill's Association movement, which identified "Parliamentary Reform" as its primary aim. Reform is generally regarded as antithetical to revolution. Developing countries may implement a range of reforms to improve living standards, often with support from international financial institutions and aid agencies. This can involve reforms to macroeconomic policy, the civil service, and public financial management. In politics, there is debate over what constitutes reform vs. revolution, and whether all changes labeled "reform" actually represent progress. For example, in the United States, proponents of term limits or rotation in office consider it a revolutionary method (advocated as early as the Articles of Confederation) for rooting out government corruption by altering ...

Euromod
Euromod, officially stylised as EUROMOD, is a European Union-wide tax-benefit model originally maintained, developed and managed by the Institute for Social and Economic Research at the University of Essex. Since 2021 Euromod is maintained, developed and managed by the Joint Research Centre of the European Commission, in collaboration with Eurostat and national teams from the EU countries. It belongs to the class of static microsimulation Microsimulation is the use of computerized analytical tools to perform analysis of activities such as highway traffic flowing through an intersection, financial transactions, or pathogens spreading disease through a population on the granularity ... models and has modules for all 27 EU member states (and the UK until 2021).

European Union
The European Union (EU) is a supranational union, supranational political union, political and economic union of Member state of the European Union, member states that are Geography of the European Union, located primarily in Europe. The union has a total area of and an estimated population of over 449million as of 2024. The EU is often described as a ''sui generis'' political entity combining characteristics of both a federation and a confederation. Containing 5.5% of the world population in 2023, EU member states generated a nominal gross domestic product (GDP) of around €17.935 trillion in 2024, accounting for approximately one sixth of global economic output. Its cornerstone, the European Union Customs Union, Customs Union, paved the way to establishing European Single Market, an internal single market based on standardised European Union law, legal framework and legislation that applies in all member states in those matters, and only those matters, where the states ...

Brexit
Brexit (, a portmanteau of "Britain" and "Exit") was the Withdrawal from the European Union, withdrawal of the United Kingdom (UK) from the European Union (EU). Brexit officially took place at 23:00 GMT on 31 January 2020 (00:00 1 February 2020 Central European Time, CET). The UK, which joined the EU's precursors the European Communities (EC) on 1 January 1973, is the only member state to have withdrawn from the EU, although the territories of Greenland (part of the Kingdom of Denmark) previously left the EC in 1985 and Algeria (formerly French Algeria, part of France) left in 1976. Following Brexit, EU law and the Court of Justice of the European Union no longer have Primacy of European Union law, primacy over British laws but the UK remains legally bound by obligations in the various treaties it has with other countries around the world, including many with EU member states and indeed with the EU itself. The European Union (Withdrawal) Act 2018 retains relevant EU law as La ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agent-based Model
An agent-based model (ABM) is a computational model for simulating the actions and interactions of autonomous agents (both individual or collective entities such as organizations or groups) in order to understand the behavior of a system and what governs its outcomes. It combines elements of game theory, complex systems, emergence, computational sociology, multi-agent systems, and evolutionary programming. Monte Carlo methods are used to understand the stochasticity of these models. Particularly within ecology, ABMs are also called individual-based models (IBMs). A review of recent literature on individual-based models, agent-based models, and multiagent systems shows that ABMs are used in many scientific domains including biology, ecology and social science. Agent-based modeling is related to, but distinct from, the concept of multi-agent systems or multi-agent simulation in that the goal of ABM is to search for explanatory insight into the collective behavior of agents ...

Computational Resource
In computational complexity theory, a computational resource is a resource used by some computational models in the solution of computational problems. The simplest computational resources are computation time, the number of steps necessary to solve a problem, and memory space, the amount of storage needed while solving the problem, but many more complicated resources have been defined. A computational problem is generally defined in terms of its action on any valid input. Examples of problems might be "given an integer ''n'', determine whether ''n'' is prime", or "given two numbers ''x'' and ''y'', calculate the product ''x''*''y''". As the inputs get bigger, the amount of computational resources needed to solve a problem will increase. Thus, the resources needed to solve a problem are described in terms of asymptotic analysis, by identifying the resources as a function of the length or size of the input. Resource usage is often partially quantified using Big ''O'' notation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
