    Talouden kehitystä kuvaavat tilastoaineistot valmistuvat viiveellä, ja tilastojen lukuja tarkennetaan eli revisioidaan lähdeaineistojen täydentyessä ja tarkentuessa. Tässä artikkelissa tarkastellaan kansantalouden neljännesvuositilinpidon tavaroiden ja palveluiden tilin (entinen huoltotase) revisioita. Artikkelissa kuvaillaan Suomen bruttokansantuotteen kausitasoitetun volyymin ja sen kysyntäerien revisioita ja testataan mahdollisuuksia ennakoida revisioita. BKT:n kasvun estimaatit ovat tulosten mukaan hieman harhaisia tarkastelujakson aikana, ja revisiot ovat suurimmillaan suhdanteen käännepisteissä sekä kahdella ensimmäisellä vuosineljänneksellä. BKT:n neljännesvuosikasvun revisiot eivät ole ennakoitavissa pelkkää BKT-aineistoa käyttämällä, mutta tavaroiden ja palveluiden tilin tilastollisella erolla on jonkin verran ennustekykyä. Kysyntäeristä mittaluokaltaan suurimmat revisiot ovat voimakkaasti vaihtelevilla tuonnilla ja viennillä, mutta nettoviennin revisiot jäävät pieniksi tuonnin ja viennin tarkentuessatyypillisesti samaan suuntaan. Yksityisen kulutuksen revisiot ovat maltillisia, mutta erän suuresta koosta johtuen revisiot ovat merkittäviä kokonaiskysynnän kannalta.

    Indicators based on the ratio of credit to GDP have been found to be highly useful predictors of banking crises. We study the difference in this ratio as an early warning indicator. We test a large number of different versions of the differenced credit-to-GDP ratio with data on Euro area members. The optimal time interval of the difference is about two years. Using the moving average of GDP instead of the latest annual data has little impact on forecasting performance. The indicator is a particularly promising choice at relatively short forecasting horizons, such as two or three years.

    We provide preliminary evidence of potential risk reduction benefits from banks’ loan portfolio diversification cross-border within the Euro area. Using aggregate data on banking sector cor-porate loan losses for each Euro area member-state, our estimates suggest that the static diversification benefit could be substantial. The minimum capital needed to withstand the max-imum annual loss from a hypothetical fully diversified Euro area bank loan portfolio over the period 2001-2017 would have been only 40 % of the total capital needed to withstand the maximum losses on a country by country basis. We also calibrate the country-specific loan loss distributions and the Euro area portfolio’s loss distribution to the Vasicek (2002) model, which underlies the Basel framework’s Internal Ratings Based Approach. We find that the im-plied asset correlation parameter of a median country portfolio is about twice as large as that of the fully diversified Euro area portfolio.

    In this paper, we estimate a potential output model for Finland using an unobserved component model. The model builds on a production function approach, and features price and wage Phillips curves, Okun’s law and several resource-utilization indicators. We show that incorporating resource-utilization indicators, i.e. capacity utilization and long-term unemployment, improves real-time reliability of the output gap and NAWRU estimates. Our real-time estimate of the output gap is robust even in an event of a sudden turning point in the economy such as the global financial crisis. It also outperforms the HP filter estimate. Results suggest that Finland’s potential output growth slowed significantly in the aftermath of the financial crisis and that the output gap was negative for most of the subsequent decade. The slowdown in potential growth was due mainly to lackluster total factor productivity growth. The real-time results are broadly in line with the ex-post estimates of the IMF and the European Commission.

    The impact of digitalisation is not fully reflected in economic statistics. Even though commonly used economic metrics such as GDP are still relevant in assessing the state of the economy, the production of statistics should be developed to measure the digital economy better. The most significant measurement challenges caused by digitalisation relate to new goods, free services, changes in quality and the movement of intellectual capital between countries. Due to digitalisation, GDP and productivity growth may have been understated and the rate of price inflation overstated. Measurement errors alone do not explain the exceptionally weak development in recent years, nor do they eliminate the problems of the Finnish economy and the key challenges for economic policy. Digital technology has, however, improved our well-being in ways that are difficult to measure in money.
