The diagram shows what happened to the consumption of lamb in the UK over the period 1974– 2015. How can we explain this dramatic fall in consumption? One way of exploring this issue is to make use of a regression model, which should help us to see which variables are relevant and how they are likely to affect

UK consumption of lamb: 1974–2017
The following is an initial model fitted to annual data for the years 1974–2010.
QL = 144.0 – 0.137PL – 0.034PB + 0.214PP – 0.00513Y + e (1)
where:
QL is the quantity of lamb sold in grams per person per week; PL is the ‘real’ price of lamb (in pence per kg, 2000 prices); PB is the ‘real’ price of beef (in pence per…
10.14 Total economic output in three years. The n - vector xt denotes the economic output of a country in n different sectors, in yeart. An economist models the economic output using a linear dynamical system model xt+1 = Axt, where A is an n \times n matrix. Assuming her model is correct, find an expression for the total economic output in yeart + 3, in terms of xt and A. (The total economic output is the sum of the economic output in the n sectors.)
Refer to the statement below and answer the following questions:
Chief statistician Datuk Seri Dr Mohd Uzir Mahidin said Malaysia is expected to continue recording a slower economic growth in 2Q 2020 due to the Covid-19 pandemic, based on the near-term economic direction portrayed by the Leading Index (LI) for the reference month of February 2020.
Mohd Uzir said GDP growth for 1Q 2020, meanwhile, was dragged by negative growth across all sectors except for services and manufacturing which grew 3.1% and 1.5% respectively.
"Private final consumption expenditure in this quarter was on essential products such as food and non-alcoholic beverage, communication and housing, water, electricity and other fuels," he said in a statement on Malaysia's economic performance in 1Q 2020, today.
He added that the Movement Control Order (MCO), which began on March 18, has resulted in lower household expenditure, which in turn, directly affected the industries related to food and beverage,…

On an annualised basis, theeconomy grew 4.6% quarter-on-quarter. Following confusion caused by the annualisation of GDP data in 2020 – amid the Covid-19 pandemic andresulting lockdowns – Stats SA said it would no longer use the annualised data as the headline GDP statistic. During periods of steady economic growth, annualising is a useful way of expressing quarter-on-quarterperformance in annual terms, Stats SA said. However, during periods of economic instability, annualising can be misleading, because it exaggerates growth rates that are unlikely to be repeated.
