Market reduction approach

Market reduction approach is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Market reduction approach rather than just read about it. In short: Market reduction approach (MRA) is an approach to reducing crime by reducing the opportunity for thieves to fence or resell what they have stolen. History Early In 1796, the London magistrate Patrick Colquhoun observed that "[i]t rarely happens that thieves go upon the highway, or commit burglaries, until the money they have previously acquired is exhausted," and that "...without a safe and ready market he [the thie…

Key takeaways

  • Market reduction approach belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Market reduction approach to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Market reduction approach from memory before moving on to harder problems.

Reference excerpt

Market reduction approach (MRA) is an approach to reducing crime by reducing the opportunity for thieves to fence or resell what they have stolen.

History

Early In 1796, the London magistrate Patrick Colquhoun observed that "[i]t rarely happens that thieves go upon the highway, or commit burglaries, until the money they have previously acquired is exhausted," and that "...without a safe and ready market he [the thief] is undone." Recognizing the key role played by dealers in stolen goods in facilitating profit from theft and motivation for offenders to steal and with an aim to influence harsher legislation and sentencing of professional fences, the American jurisprudentialist Jerome Hall emphasised the role of the professional fence in the marketing of stolen goods and created a typology that distinguished between professional fences, part-time dealers, and those who knowingly buy stolen goods for their own consumption. A number of ethnography studies (e.g. Klockars 1974; Henry 1977 and Steffensmeir 1986) hinted at the influence of the market for stolen goods upon levels of theft of certain goods. A systematic study of the various ways that stolen goods are stored, sold and bought – going beyond the previous focus upon the guilty mind and level of involvement of dealers and consumers – was conducted by Mike Sutton, who created a fivefold market typology based on his interviews with expert prolific thieves, inexperienced thieves, fences, drug dealers and stolen goods consumers. In 1998, the UK Home Office published Sutton's report proposing a systematic framework for researching and tackling local stolen goods markets.

Modern Current development of the market reduction approach (MRA) has its origins in a 1995 British Journal of Criminology paper: Supply by Theft that was followed by a 1998 United Kingdom Government Home Office research study entitled Handling Stolen Goods and Theft: A Market Reduction Approach, both written by Mike Sutton Further work on implementing and process evaluation of the MRA was conducted by Schneider. Described by Marcus Felson as "...a simple idea in an important article" and as classic research, Sutton's concept of MRA has had an influence upon theory and practice regarding stolen goods markets and markets for other illicit commodities. Some criminologists have incorporated Sutton's work on stolen goods markets to explain the issue of offenders’ capacity to commit crimes. The general MRA principles have influenced work beyond research into markets for theft of high volume consumer goods, since the MRA is described as underpinning recent research into illicit markets for cultural artefacts and as a useful method for tackling the trade in endangered species. Sutton's 1998 stolen goods Handling Report includes findings from the nationally representative British Crime Survey (1994). This revealed that 11 percent of those questioned had bought stolen goods in the preceding five years, and that 70 percent believed that some of their neighbours had stolen goods in their homes. The Handling Report was followed by a more comprehensive MRA policing guide to stolen goods markets.

Application Kent constabulary were the first to experiment with the MRA in Operation Radium. This experiment at systematically tackling stolen goods markets, along with another MRA initiative by the Greater Manchester Police, as routine policing (rather than merely cracking down from time to time) was independently evaluated by criminologists from The University of Kent. The evaluation found that while the MRA theory remains sound that the police forces experienced organisational difficulties implementing it correctly. Based on Situational Crime Prevention (SCP) "rational choice, opportunity reduction" principles, and employing philosophy from routine activity theory (RAT) the MRA is designed to reduce theft through reducing the demand for stolen goods that motivated thieves to steal. In addition it seeks to make handling stolen goods at least as difficult as it is to steal them and to increase the risks of detection for all those selling and buying stolen goods. In this way the MRA answered a long-standing academic criticism that SCP and RAT did not take account of offender motivation. MRA principles are now firmly established within both SCP RAT and Problem Oriented Policing (POP) key texts. The MRA has been implemented in the United Kingdom by Kent Constabulary, West Mercia Constabulary, Derby City Constabulary, Nottinghamshire Constabulary, and Greater Manchester Police. It is recommended crime reduction practice by the UK United States, and Australian governments. The New Zealand Ministry of Justice conducted a review of research focused on the MRA and identified eight areas of good practice in using it to tackle property crime. In 2008, the MRA has been applied to research focused upon tackling markets for endangered species.

The MRA and problem oriented policing Introducing a sixth market type, e-fencing, the MRA is used by the US Department of Justice, Office of Community Oriented Policing Services, to combat crime with the problem-oriented approach to policing.

Worked examples

Example 1 — a first encounter with Market reduction approach

Start with the simplest possible case. Write down what Market reduction approach claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Market reduction approach before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Market reduction approach ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Market reduction approach

In research
Market reduction approach appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Market reduction approach in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Market reduction approach is common in secondary-school and first-year university syllabi. It links to neighbouring topics Criminology, so understanding it makes those chapters shorter.
In everyday life
Look for Market reduction approach outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
